Postop delirium management proposed as hospital performance measure
A study suggests that
outcome measures, and assessment of hospital performance.Lead author Julia R. Berian, MD, of the University of Chicago Medical Center and her colleagues wrote, “Postoperative delirium has been associated with mortality, morbidity, prolonged length of stay, and increased costs of care. Furthermore, postoperative delirium may be associated with long-term cognitive and functional decline. However, postoperative delirium has not been incorporated as an outcome measure into major surgical quality registries. Approximately one-third of hospitalized delirium is believed to be preventable, making postoperative delirium an ideal target for surgical quality improvement efforts,” Dr. Berian and her colleagues reported in the Annals of Surgery.
The Geriatric Surgery Pilot data abstractors were instructed to assign postoperative delirium if the medical record words indicating an acute confusional stat such a mental status change, confusion, disorientation, agitation, delirium, and inappropriate behavior. Data were collected from the period 2 hours after surgery to exclude effects of the pharmacologic agents of anesthesia. Delirium status was ascertained as a binary outcome (Yes/No).
Postoperative delirium was observed in 2,427 patients for an average, unadjusted rate of 12.0%. Investigators identified 20 risk factors markedly associated with delirium. The strongest predictors included preoperative cognitive impairment, preoperative use of mobility aid, surrogate consent form, ASA class 4 or greater, age 80 years and older, preoperative sepsis, and fall history within 1 year. Patients with delirium generally were older than patients without delirium were and accounted for a greater proportion of emergency cases. Postoperative hospital length of stay was about 4 days longer on average for patients with delirium, compared with those without delirium.
By specialty, the highest rates of postoperative delirium occurred following cardiothoracic (13.7%), orthopedic (13.0%), and general surgeries (13.0%). Study authors found varied associated risk for postoperative delirium within each surgical specialty. For example, in general surgery, the risk for postoperative delirium with partial mastectomy was low, compared with a mid-level risk in the repair of a recurrent, incarcerated, or strangulated inguinal hernia and a high-level risk in Whipple operations.
The model developed to measure delirium management success in 30 hospitals found that adjusted delirium rates ranged from 3.2% to 27.5%, with eight poor- and five excellent-performing outliers. Authors noted that their model demonstrated good calibration and discrimination. Examination of changes in the Bayesian Information Criteria indicates that as few as 10-12 variables may suffice in building a parsimonious model with “an excellent fit.”
Study authors noted that screening for postoperative delirium in older adults is likely in the best interests of patients. However, they also mentioned that such screening may identify cases of postoperative delirium that were previously unrecognized, resulting in higher rates. In addition, the inclusion of only ACS NSQIP hospitals and the voluntary participation may mean a biased dataset. No one delirium prevention intervention was implemented across the hospitals and so the study doesn’t indicate why some hospitals are more successful than are others. Chart-based identification of patients who have delirium needs further study to assess validity.
Authors concluded that one solution may be to “standardize and consistently employ delirium screening in high-risk patients across hospitals, as has been advocated by a coalition of interdisciplinary experts in geriatric care.”

Fake medical news: The black salve and the black arts
Jake clearly needed a biopsy.
When I suggested that we find out what that new growth on his cheek was, he responded with fear. “Do you really need to test it?” he asked. Then he proposed an alternative.
“I had another spot last year,” he said. “This European doctor I saw in somebody’s home put a special black salve on it, and it went away.”
“Who was this doctor?” I asked.
“At the time, I was a raw vegan,” he said. “One of our group members gave me the doctor’s name. He has a big reputation in Europe. He treated people locally in people’s living rooms.”
“Do you recall his name?” I asked him.
Jake didn’t. But I did.
Three years ago, a frightened, middle-aged woman named Josie came to see me with ugly scarring all over her face.
Josie’s story was similar to Jake’s: A famous European doctor. Somebody’s living room.
“He had me lie on the floor,” she recalled, “and he put on some kind of salve. It burned horribly. I was screaming in pain. He washed it off, but it still burned for a long time. This is what it left,” she said, pointing to denting and discoloration on her cheeks and upper lip. She remembered the man’s name.
It took just a few clicks to find him. He wasn’t a licensed doctor and had fled his home country ahead of fraud charges for illegal and harmful practice.
I couldn’t offer Josie much, beyond advising her to avoid getting treated on living room floors by strange practitioners with painful salves.
If you don’t know about the treatment Josie and Jake underwent – it’s called “escharotic treatment” – you can look it up on Wikipedia. It’s also the topic of a case study in the May issue of JAMA Dermatology (2018;154[5]:618-9).
Escharotic treatment has been around a long time. It is used for cancers of the skin and cervix, among others. The principle behind The idea behind both is to apply something that blisters the skin and raises a scab. The eschar is supposed to draw the evil out of the body and bring cure.
Smile if you want, but this idea has been around forever and will likely outlast many treatments we now use. Fake news is old news, and does not need social media to spread (though Facebook helps).
Apparently ordinary people believe strange, irrational, harmful things. Why? Why on earth would Jake and Josie let somebody they don’t know put black goop that hurts like hell on their faces as they lie on a stranger’s carpet? Some thoughts:
- Fear. They think they have cancer and are afraid to find out.
- Suspicion. They don’t trust doctors.
- People they hang with tell them to. Some groups harbor a suspicious, even hostile stance toward conventional medicine, convinced that its principles are unnatural and its practitioners are more concerned with profit and prestige than with the good of their patients.
Those who hold such beliefs, like various conspiracy theorists, span the political and social spectrum, from left to right, and they’ve been around forever.
I don’t plan to try convincing them otherwise. No one can convince them. Citing facts and authority gets you nowhere. As Jonathan Swift said, “You cannot reason someone out of something they did not reason themselves into.”
Fake political news is a problem for society. Fake medical news can be a problem for doctors. A pediatrician confronting an antivaxer family must decide whether to try negotiating (giving their kid vaccines a little at a time) or to give up and send them elsewhere.
It takes effort for physicians to have patience with people who let unscrupulous strangers etch and mutilate their faces. As professionals, however, we doctors are obligated to care even for people we don’t like or agree with. We should therefore try to understand why people who undertake dangerous and irrational treatments think the way they do.
Often, what such patients mainly are is afraid. Still, the ones who actually show up in our offices are willing to at least consider medical opinion. Those who aren’t would never show up.
Jake had enough faith in me to let me calm him down enough to do the biopsy.
It was benign.

Study Reaffirms Tenofovir’s Safety for Pregnant Women
A reanalysis of 2 National Institutes of Health (NIH)-funded studies refutes the conclusions of PROMISE (Promoting Maternal and Infant Survival Everywhere), which found tenofovir disoproxil fumarate (TDF) combination treatment raised the risk of adverse outcomes.
The PROMISE study compared several treatments in pregnant women with HIV in India and Africa. According to those researchers, women on TDF regimens were twice as likely as those on zidovudine to have a very preterm infant, and their infants were more likely to die within the first 2 weeks.
Those results surprised the current researchers, given that other, earlier studies had found TDF combinations safe for use during pregnancy. In fact, the World Health Organization recommends that all adults with HIV, including pregnant women, receive TDF combination therapy.
In the current study, NIH researchers compared outcomes from 2 US studies, reviewing records on more than 4,600 infants born to 3,847 women. The women were on either a combination regimen including zidovudine or 1 containing TDF.
The researchers found no significant differences in the risk of preterm birth or low birth weight, nor did they find any significant difference in severe birth outcomes, including infant death, in the first 2 weeks. “Notably,” they add, comparing women on zidovudine combination treatment with TDF/emtricitabine/atazanavir/ritonavir, the researchers found the TDF group had a 10% lower chance of preterm birth, low birth weight, and infant death.

Erenumab May Control Migraines When Other Preventives Have Failed
LOS ANGELES—Patients who have tried and failed other preventive therapies may find that erenumab can prevent their migraines, according to a study presented at the 70th Annual Meeting of the American Academy of Neurology. Erenumab is a fully human monoclonal antibody that inhibits the calcitonin gene-related peptide (CGRP) receptor.
Current oral preventive therapies are associated with low adherence rates due to their lack of efficacy or poor tolerability. Therefore, researchers thought it important to assess the safety and efficacy of erenumab in patients who had failed multiple therapies. A previous post hoc analysis of the STRIVE study showed that patients who had failed two prior preventives responded to erenumab. “Their odds ratio was far greater than [that of] those who were previous preventive naïve,” said Peter J. Goadsby, MD, PhD, who presented the newest erenumab data in the Emerging Science plenary session. Dr. Goadsby is a Professor of Neurology at Kings College London and the University of California, San Francisco.
“The people we included in our study were considered more difficult to treat, meaning that up to four other preventive treatments had not worked for them,” said lead study author
The LIBERTY Study
The LIBERTY study was a phase IIIb, randomized, double-blind, placebo-controlled trial thta assessed erenumab in patients who had failed at least two and not more than four prior preventives. A total of 246 patients with episodic migraine were randomized one to one to an injection of erenumab (140 mg) or placebo once per month for three months. There were 125 patients in the placebo arm and 121 in the erenumab arm. The primary end point was the proportion of patients achieving a 50% or greater reduction in mean monthly migraine days (MMDs) during weeks nine to 12 (ie, month three) of the study. Secondary end points included change from baseline to month three in MMDs and monthly acute migraine-specific medication days (MSMDs) and safety and tolerability.
At baseline, 39% of participants had been treated unsuccessfully with two other medications, 38% with three medications, and 23% with four medications. On average, participants had nine migraine days per month and used an acute migraine drug to stop an attack five times per month.
At week 12, the proportion of patients achieving a 50% or greater reduction in MMDs was higher in those treated with erenumab versus placebo (30.3% vs 13.7%). At week 12, there were greater reductions in MMDs and MSMDs with erenumab versus placebo. The safety and tolerability of erenumab were comparable to those of placebo. No patients in the erenumab group discontinued treatment due to adverse events.
Hope for Refractory Patients?
LIBERTY is the first dedicated study to address a problem that is all too common in neurology, said Dr. Goadsby. “It is hard to deal with patients who have failed prior preventives.” Erenumab, he said, is the first of the CGRP monoclonal antibodies to “control migraine and prevent migraine in patients who are so disabled and whom we cannot treat with current medicine.”
“Our results show that people who thought their migraines were difficult to prevent may actually have hope of finding pain relief,” said Dr. Reuter. “More research is now needed to understand who is most likely to benefit from this new treatment.”

Dr. Goadsby is a Professor of Neurology at Kings College London and the University of California, San Francisco.
“The people we included in our study were considered more difficult to treat, meaning that up to four other preventive treatments had not worked for them,” said lead study author
The LIBERTY Study
The LIBERTY study was a phase IIIb, randomized, double-blind, placebo-controlled trial thta assessed erenumab in patients who had failed at least two and not more than four prior preventives. A total of 246 patients with episodic migraine were randomized one to one to an injection of erenumab (140 mg) or placebo once per month for three months. There were 125 patients in the placebo arm and 121 in the erenumab arm. The primary end point was the proportion of patients achieving a 50% or greater reduction in mean monthly migraine days (MMDs) during weeks nine to 12 (ie, month three) of the study. Secondary end points included change from baseline to month three in MMDs and monthly acute migraine-specific medication days (MSMDs) and safety and tolerability.
At baseline, 39% of participants had been treated unsuccessfully with two other medications, 38% with three medications, and 23% with four medications. On average, participants had nine migraine days per month and used an acute migraine drug to stop an attack five times per month.
At week 12, the proportion of patients achieving a 50% or greater reduction in MMDs was higher in those treated with erenumab versus placebo (30.3% vs 13.7%). At week 12, there were greater reductions in MMDs and MSMDs with erenumab versus placebo. The safety and tolerability of erenumab were comparable to those of placebo. No patients in the erenumab group discontinued treatment due to adverse events.
Hope for Refractory Patients?
LIBERTY is the first dedicated study to address a problem that is all too common in neurology, said Dr. Goadsby. “It is hard to deal with patients who have failed prior preventives.” Erenumab, he said, is the first of the CGRP monoclonal antibodies to “control migraine and prevent migraine in patients who are so disabled and whom we cannot treat with current medicine.”
“Our results show that people who thought their migraines were difficult to prevent may actually have hope of finding pain relief,” said Dr. Reuter. “More research is now needed to understand who is most likely to benefit from this new treatment.”

LOS ANGELES—Patients who have tried and failed other preventive therapies may find that erenumab can prevent their migraines, according to a study presented at the 70th Annual Meeting of the American Academy of Neurology. Erenumab is a fully human monoclonal antibody that inhibits the calcitonin gene-related peptide (CGRP) receptor.
Current oral preventive therapies are associated with low adherence rates due to their lack of efficacy or poor tolerability. Therefore, researchers thought it important to assess the safety and efficacy of erenumab in patients who had failed multiple therapies. A previous post hoc analysis of the STRIVE study showed that patients who had failed two prior preventives responded to erenumab. “Their odds ratio was far greater than [that of] those who were previous preventive naïve,” said Peter J. Goadsby, MD, PhD, who presented the newest erenumab data in the Emerging Science plenary session.

Genes, not adiposity, may be driving appetite differences in obesity
BOSTON – Evidence from a twin study points to genes, rather than just adiposity, as the underlying factor in differences in appetite and satiety that have been observed in obesity.

The work adds a new dimension – and some questions – to previous research, which suggested individuals with obesity show heightened brain activation to food cues, especially calorically dense food.
“We thought it was fat mass…but when we controlled for everything that monozygotic pairs have in common, that relationship went away, implicating something that the monozygotic twins have in common, i.e., genetics,” said first author Jennifer Rosenbaum, MD, in a video interview at the annual meeting of the American Academy of Clinical Endocrinologists.
Dr. Rosenbaum, a fellow in the department of metabolism, endocrinology, and nutrition at the University of Washington, Seattle, and her collaborators made use of a statewide twin registry to conduct an extensive investigation of subjective and objective measures of appetite and satiety in the 42 twin pairs.
Twins had a mean age of 31 years; 27 of the twin pairs were monozygotic, Dr. Rosenbaum said. At least one member of each twin pair met criteria for obesity, and participants had a mean body mass index of 32.8 kg/m2.
On the study day, participants arrived in fasting state, and had a fixed-calorie breakfast equivalent to 10% of their daily caloric needs. They then underwent dual-energy x-ray absorptiometry scanning to determine adiposity, and also filled out a behavioral questionnaire.
Then, participants received the first of two functional MRI scans; during the scan, they were shown images of high calorie foods, low calorie foods, and nonfood objects, completing ratings of how appealing they found each image. After consuming another standardized meal equivalent to 20% of daily caloric needs, the fMRI scan was repeated.
Finally, participants were given access to a buffet meal and allowed to eat as much as they chose; consumption was measured. Before and after each meal and scan, and at various points during the day, the investigators also obtained blood samples and asked participants to rate their hunger on a visual analog scale.
“When compared with how much fat mass they had, there was no relationship between how hungry or full they were when they were fasting, how hungry or full they were with a snack, or when they ate the buffet. It just didn’t matter how much fat mass they had” for subjective reporting of hunger and fullness, said Dr. Rosenbaum.
However, there was a direct correlation between fat mass and amount consumed at the ad libitum buffet. Additionally, the fMRI analysis showed that “the brain activation that we would expect to go down, didn’t seem to go down as much if you had more adiposity,” she said.
As fat mass went up, areas of the brain implicated in appetite and reward showed more activity when participants were presented with the tempting images of high calorie foods, regardless of the calories consumed. These areas include the ventral and dorsal striata, the amygdala, the insula, the ventral tegmental area, and the medial orbitofrontal cortex.
Next, the researchers looked for differences within the monozygotic twin pairs, who essentially share a genome. They compared the brain activation of the twin with the higher fat mass with that of the twin with lower fat mass. Instead of seeing the same correlation between higher adiposity and greater brain activation with tempting stimuli, “Suddenly, we lost that relationship between how many calories they would eat and how their brain activated with the food,” said Dr. Rosenbaum. This is a clue, she said, that genetics, rather than simple adiposity, is driving the different responses to food cues.
The study was funded by the National Institutes of Health. Dr. Rosenbaum reported no financial disclosures.

Experimental drug may help those living with celiac disease
“Contamination with gluten happens during food processing, food packaging, cooking, and [because of] inadequate labeling,” Francisco Leon, MD, a consultant for Amgen and former CEO of Celimmune, said in a media briefing in advance of the annual Digestive Disease Week® (DDW). “Gluten is [also] present in unsuspected places like lipstick, toothpaste, even medicines. It is virtually impossible for celiac patients to completely avoid gluten.”
The new drug, AMG 714, works by blocking interleukin 15, a known intestinal inflammatory mediator, and lowers inflammation, resulting in fewer symptoms for patients.
In a 12-week study, patients received either 150- or 300-mg doses of subcutaneous AMG 714, or placebo. All doses of AMG 714 were administered six times over the course of the study. From weeks 2 to 12, patients were challenged with a daily dose of 2.5 grams of gluten, which is considered a high dose.
The results showed that AMG 714 significantly reduced Celiac Disease Patient Reported Outcomes at the 300-mg dose (P = .02) compared with placebo. Similarly, AMG 714 decreased Celiac Disease Gastrointestinal Symptom Rating Scale scores at the 150-mg (P = .17) and 300-mg (P = .07) doses, compared with placebo.
Dr. Leon noted that there was another subset of patients who did not receive the gluten challenge because they were shown to have intestinal atrophy – marked by the presence of flat mucosa – because of contamination in their gluten-free diets. This was measured by way of a novel stool and urine detection test. This information will be presented at DDW.
AMG 714 also improved gluten-triggered diarrhea and physician assessments, according to Dr. Leon. In fact, using the Bristol Stool Form Scale, patients who received both the 150-mg (P = .01) and 300-mg (P = .0002) doses had substantially lower rates of diarrhea, compared with placebo.
These positive results were not isolated to the Bristol Stool Form Scale scores, but extended to the Physician Global Assessment as well.
“The proportion of subjects whom physicians evaluated as clinically active at week 12 was 0 in the high dose of AMG 714 while it was 33% in the placebo group,” stated Dr. Leon.
While AMG 714 has shown promise in alleviating celiac disease symptoms for patients inadvertently exposed to gluten, it is not intended to treat exposure to high amounts of gluten.
“It is important to note that AMG 714 is intended to protect against modest contamination [with] gluten and not against the effects of regularly eaten large amounts of gluten, like bread or pasta,” Dr. Leon cautioned. “But we know that people with celiac disease are inadvertently exposed to gluten. So it is our hope that AMG 714 will allow these patients to experience fewer gluten-triggered events.”
The information presented by Dr. Leon was only a taste of what will be presented at DDW®.
“At DDW, we will show you a reduction in inflammation, and we will also show you the safety profile. There were no serious adverse events.
“We are hopeful that this will become one of the tools to combat celiac disease.”

Ureteral reimplantation for injuries not easily managed with stenting
The risk of lower urinary tract injury (bladder or ureters) at the time of benign gynecologic surgery is estimated to be between 0.3% and 4%. The majority are bladder injuries, with ureteral injuries occurring in 0.3%-1.8% of hysterectomies. While urologic procedures account for the majority of iatrogenic ureteral injuries, gynecologic surgery is the second leading cause, followed by general surgery and colorectal surgery.
With respect to hysterectomy in particular, the risk of ureteral injury is less than 1%. In a large prospective cohort of women undergoing hysterectomy for benign indications in 53 hospitals in Finland, rates of ureteral injury varied based on the route of hysterectomy, with laparoscopic and abdominal routes having an injury rate of 0.3% and the vaginal route having an injury rate of 0.04% (Human Reprod. 2011;26[7]:1741-51). The risk generally is higher with procedures for endometriosis, large fibroids, cancer, or pelvic organ prolapse.
During hysterectomy and with gynecologic surgery overall, ureteral injuries occur most commonly at three locations: at the level of the infundibulopelvic ligament and ovarian vessels, at the level of the uterine artery, and near the vaginal cuff. Identification and knowledge of the course of the ureter at these three locations is essential in preventing ureteral injury during pelvic surgery.

SOURCE: DR. MUELLER AND DR. KENTON
Perioperative ureteral stenting has been proposed as a method of preventing iatrogenic injury by allowing surgeons to more easily identify the ureters during surgery. Available reports suggest, however, that the actual risk of injury is not decreased and may even be increased by placing prophylactic ureteral stents, and most surgeons have moved away from this practice. The use of lighted ureteral stents during complex laparoscopic endometriosis resections may be helpful.
Many health care systems recommend intraoperative cystoscopy with bladder and ureteral survey to evaluate the integrity of the lower urinary tract at the time of all hysterectomies. A recent study of nearly 3,000 women undergoing benign hysterectomies at the University of Michigan, Ann Arbor, showed a significant decrease in the rate of delayed diagnosis of urinary tract injuries with implementation of a universal cystoscopy policy. While the rate of lower urinary tract injury was fairly consistent before and after implementation of the policy (2.6% and 1.8%, respectively), the rate of delayed detection of a lower urinary tract injury decreased from 0.7% before the policy to 0.1% after implementation (Obstet Gynecol. 2016;127[2]:369-75). The study also showed that hospital costs nearly doubled with a delayed detection of a lower urinary tract injury.
Unfortunately, even a normal postoperative cystoscopy does not ensure there is no lower urinary tract injury, especially considering that thermal injuries resulting from the use of energy devices typically do not present until 7-14 days after surgery. Overall, however, ureteral injury detection rates with universal cystoscopy approach 97% (Obstet Gynecol. 2009;113:6-10).
Identifying injuries
Intraoperative recognition and repair always is preferred, and when ureteral injuries are discovered or suspected in the operating room, cystoscopy and retrograde pyelography is the most helpful imaging tool. Contrast dye is injected during cystoscopy directly into the renal collecting system through the ureteral orifices; with fluoroscopy, the surgeon can visualize the integrity of the ureter from the bladder to the renal pelvis to diagnosis a ureteral injury, including ureteral transection, kinking, or ligation caused by a suture or sealing device.
If retrograde pyelography shows a transection or injury from a crushing clamp or sealing device, we recommend ureteroureteral anastomosis or urethral neocystostomy depending on the extent and location of the injury. If the ureter just appears kinked, sometime simply releasing the cuff sutures or uterosacral ligament sutures will resolve the obstruction. If there is extravasation of contrast suggesting a partial tear, placing a double-J ureteral stent for 6-8 weeks is frequently sufficient.
Patients with delayed iatrogenic ureteral injuries present with symptoms that often are nonspecific and that include abdominal or flank pain, fever, nausea, vomiting, back pain, and leukocytosis.
We recommend that patients with a history of surgery and symptoms suggestive of a ureteral injury be initially evaluated with CT urography that images the renal collecting system both as contrast dye is instilled and again several minutes later as it has progressed through the entire urinary tract. Alternatively, if CT urography is unavailable, a retrograde pyelogram can be performed as an emergency procedure to determine the location of renal injury.
Surgical management
Delayed ureteral injuries resulting in partial ureteral obstruction or extravasation of urine into the pelvis can sometimes be managed conservatively though placement of an internalized double J stent. The stent can be placed in a retrograde fashion via cystoscopy by a
We typically manage delayed ureteral injuries that are not amenable to, or do not heal with, ureteral stenting with ureteroneocystotomy, or ureteral reimplantation, into the bladder. This technique is effective for distal ureteral injuries that result in obstruction or fistula and are in close proximity to the bladder (most iatrogenic gynecologic injuries). We perform ureteroneocystotomy via an open, robotic, or laparoscopic route of access depending on the circumstance.
Our preferred route of access is minimally invasive with the da Vinci robot. A camera port is placed at the umbilicus, two robotic ports are placed on the patient’s left side at the level of the umbilicus, and one is placed on the patient’s right side at the level of the umbilicus with an additional assistant port on the right side. It is helpful if each port is at least 8 cm apart. If obstruction or transection is suspected to be more proximal, the ports may have been shifted above the umbilicus to optimally mobilize the ureter.
First, the ureter is identified and dissected. Regardless of the site of injury, which is usually identifiable with inflammation and scar tissue, it is always easiest to identify the ureter at the bifurcation of the common iliac vessels. The isolated ureter is inspected proximally and above the area of injury, and we find it helpful to place a vessel loop around the ureter for easy manipulation and counter traction. Care must be taken not to disturb the adventitia and blood supply. We do not transect the ureter until we’re ready to reimplant it in the bladder.
To mobilize the bladder and prepare for a tension-free anastomosis, an adequate retropubic dissection is performed, starting with an incision in the anterior abdominal wall peritoneum and taking it down to the level of the pubic bone and into the retropubic space. It is important to be mindful of the location of the obturator neurovascular bundle when performing this dissection.
Achieving a tension-free and water-tight anastomosis of the ureter to the bladder is critical. The bladder should be mobilized such that it reaches to above the injured portion of the ureter. The bladder is retrograde filled with approximately 300 mL and a reimplantation site of the posterior bladder is identified. When there is concern about tension, a psoas hitch suture can be placed to keep the bladder in a superior position with reduced tension. Because of high rates of the congenital absence of the psoas tendon minor, we advocate direct visualization of the genitofemoral nerve by incising the peritoneum; this will avoid nerve entrapment.
Once the bladder is mobilized and the ureter isolated, we perform an intentional cystotomy in the posterior lateral aspect of the bladder. The ureter, which is on the vessel loop, must be transected proximal to the site of injury. To facilitate this, we spatulate the ureter, making a vertical incision of often about 5 mm in length to increase our surface area for anastomosis. Placement of a suture at the apex of the spatulated ureter helps us maintain orientation.
Anastomosis of the ureter and bladder is achieved in a mucosa-to-mucosa fashion using a series of interrupted monofilament fine absorbable sutures; we use a 3-0 monocryl suture. The most posterior anastomotic sutures are placed first to allow for optimal visualization, and prior to completing the anastomosis, a guide wire is placed through the open ureter and a double-J stent is introduced into the renal pelvis. The wire is then removed and the distal end of the stent coiled in the bladder. This stent will protect the ureter for about 6 weeks while it heals. The anastomosis is then completed on the anterior aspect, with a watertight closure ensured.
Postoperatively, we routinely perform an x-ray to ensure proper placement of the stent in the reimplanted ureter. To determine correct stent placement, the last rib is identified at T12 vertebrae. The renal pelvis is located at the level of the L2-L3 with the left being slightly higher than the right. A Foley catheter is maintained in the bladder for approximately 2 weeks, and the stent is maintained for approximately 6 weeks. Both the catheter and the stent can be removed in the office with cystoscopic guidance.
Imaging at 4-6 weeks after removal of the stent is performed to rule out development of an obstruction or a stricture. In patients who did not have a dilated ureter and renal collecting system prior to reimplantation, a renal ultrasound is sufficient to identify hydroureter/hydronephrosis or a urinoma. Many patients with a markedly dilated renal-collecting system prior to ureteral reimplantation will have persistent hydroureter/hydronephrosis (similar to a latex balloon that does not return to its original size after it is blown up) after reimplantation. A Lasix renal scan is a better imaging modality in these patients because it can differentiate a ureter that is dilated from one that is dilated and obstructed.
It is important to note that prompt ureteroneocystotomy is feasible only when the delayed ureteral injury presents within approximately 7 days of surgery. If the patient presents more than a week after surgery, inflammation is so significant that conservative management is necessary with reevaluation for reimplantation in another 6 weeks. Decompression of the system prior to reimplantation can be achieved through either stent placement or placement of a percutaneous nephrostomy tube. We prefer the latter because it reduces inflammation around the ureter that may make subsequent dissection and surgery more difficult.

The risk of lower urinary tract injury (bladder or ureters) at the time of benign gynecologic surgery is estimated to be between 0.3% and 4%. The majority are bladder injuries, with ureteral injuries occurring in 0.3%-1.8% of hysterectomies. While urologic procedures account for the majority of iatrogenic ureteral injuries, gynecologic surgery is the second leading cause, followed by general surgery and colorectal surgery.
With respect to hysterectomy in particular, the risk of ureteral injury is less than 1%. In a large prospective cohort of women undergoing hysterectomy for benign indications in 53 hospitals in Finland, rates of ureteral injury varied based on the route of hysterectomy, with laparoscopic and abdominal routes having an injury rate of 0.3% and the vaginal route having an injury rate of 0.04% (Human Reprod. 2011;26[7]:1741-51). The risk generally is higher with procedures for endometriosis, large fibroids, cancer, or pelvic organ prolapse.
During hysterectomy and with gynecologic surgery overall, ureteral injuries occur most commonly at three locations: at the level of the infundibulopelvic ligament and ovarian vessels, at the level of the uterine artery, and near the vaginal cuff. Identification and knowledge of the course of the ureter at these three locations is essential in preventing ureteral injury during pelvic surgery.

Perioperative ureteral stenting has been proposed as a method of preventing iatrogenic injury by allowing surgeons to more easily identify the ureters during surgery. Available reports suggest, however, that the actual risk of injury is not decreased and may even be increased by placing prophylactic ureteral stents, and most surgeons have moved away from this practice. The use of lighted ureteral stents during complex laparoscopic endometriosis resections may be helpful.
Many health care systems recommend intraoperative cystoscopy with bladder and ureteral survey to evaluate the integrity of the lower urinary tract at the time of all hysterectomies. A recent study of nearly 3,000 women undergoing benign hysterectomies at the University of Michigan, Ann Arbor, showed a significant decrease in the rate of delayed diagnosis of urinary tract injuries with implementation of a universal cystoscopy policy. While the rate of lower urinary tract injury was fairly consistent before and after implementation of the policy (2.6% and 1.8%, respectively), the rate of delayed detection of a lower urinary tract injury decreased from 0.7% before the policy to 0.1% after implementation (Obstet Gynecol. 2016;127[2]:369-75). The study also showed that hospital costs nearly doubled with a delayed detection of a lower urinary tract injury.
Unfortunately, even a normal postoperative cystoscopy does not ensure there is no lower urinary tract injury, especially considering that thermal injuries resulting from the use of energy devices typically do not present until 7-14 days after surgery. Overall, however, ureteral injury detection rates with universal cystoscopy approach 97% (Obstet Gynecol. 2009;113:6-10).
Identifying injuries
Intraoperative recognition and repair always is preferred, and when ureteral injuries are discovered or suspected in the operating room, cystoscopy and retrograde pyelography is the most helpful imaging tool. Contrast dye is injected during cystoscopy directly into the renal collecting system through the ureteral orifices; with fluoroscopy, the surgeon can visualize the integrity of the ureter from the bladder to the renal pelvis to diagnosis a ureteral injury, including ureteral transection, kinking, or ligation caused by a suture or sealing device.
If retrograde pyelography shows a transection or injury from a crushing clamp or sealing device, we recommend ureteroureteral anastomosis or urethral neocystostomy depending on the extent and location of the injury. If the ureter just appears kinked, sometime simply releasing the cuff sutures or uterosacral ligament sutures will resolve the obstruction. If there is extravasation of contrast suggesting a partial tear, placing a double-J ureteral stent for 6-8 weeks is frequently sufficient.
Patients with delayed iatrogenic ureteral injuries present with symptoms that often are nonspecific and that include abdominal or flank pain, fever, nausea, vomiting, back pain, and leukocytosis.
We recommend that patients with a history of surgery and symptoms suggestive of a ureteral injury be initially evaluated with CT urography that images the renal collecting system both as contrast dye is instilled and again several minutes later as it has progressed through the entire urinary tract. Alternatively, if CT urography is unavailable, a retrograde pyelogram can be performed as an emergency procedure to determine the location of renal injury.
Surgical management
Delayed ureteral injuries resulting in partial ureteral obstruction or extravasation of urine into the pelvis can sometimes be managed conservatively though placement of an internalized double J stent. The stent can be placed in a retrograde fashion via cystoscopy by a
We typically manage delayed ureteral injuries that are not amenable to, or do not heal with, ureteral stenting with ureteroneocystotomy, or ureteral reimplantation, into the bladder. This technique is effective for distal ureteral injuries that result in obstruction or fistula and are in close proximity to the bladder (most iatrogenic gynecologic injuries). We perform ureteroneocystotomy via an open, robotic, or laparoscopic route of access depending on the circumstance.
Our preferred route of access is minimally invasive with the da Vinci robot. A camera port is placed at the umbilicus, two robotic ports are placed on the patient’s left side at the level of the umbilicus, and one is placed on the patient’s right side at the level of the umbilicus with an additional assistant port on the right side. It is helpful if each port is at least 8 cm apart. If obstruction or transection is suspected to be more proximal, the ports may have been shifted above the umbilicus to optimally mobilize the ureter.
First, the ureter is identified and dissected. Regardless of the site of injury, which is usually identifiable with inflammation and scar tissue, it is always easiest to identify the ureter at the bifurcation of the common iliac vessels. The isolated ureter is inspected proximally and above the area of injury, and we find it helpful to place a vessel loop around the ureter for easy manipulation and counter traction. Care must be taken not to disturb the adventitia and blood supply. We do not transect the ureter until we’re ready to reimplant it in the bladder.
To mobilize the bladder and prepare for a tension-free anastomosis, an adequate retropubic dissection is performed, starting with an incision in the anterior abdominal wall peritoneum and taking it down to the level of the pubic bone and into the retropubic space. It is important to be mindful of the location of the obturator neurovascular bundle when performing this dissection.
Achieving a tension-free and water-tight anastomosis of the ureter to the bladder is critical. The bladder should be mobilized such that it reaches to above the injured portion of the ureter. The bladder is retrograde filled with approximately 300 mL and a reimplantation site of the posterior bladder is identified. When there is concern about tension, a psoas hitch suture can be placed to keep the bladder in a superior position with reduced tension. Because of high rates of the congenital absence of the psoas tendon minor, we advocate direct visualization of the genitofemoral nerve by incising the peritoneum; this will avoid nerve entrapment.
Once the bladder is mobilized and the ureter isolated, we perform an intentional cystotomy in the posterior lateral aspect of the bladder. The ureter, which is on the vessel loop, must be transected proximal to the site of injury. To facilitate this, we spatulate the ureter, making a vertical incision of often about 5 mm in length to increase our surface area for anastomosis. Placement of a suture at the apex of the spatulated ureter helps us maintain orientation.
Anastomosis of the ureter and bladder is achieved in a mucosa-to-mucosa fashion using a series of interrupted monofilament fine absorbable sutures; we use a 3-0 monocryl suture. The most posterior anastomotic sutures are placed first to allow for optimal visualization, and prior to completing the anastomosis, a guide wire is placed through the open ureter and a double-J stent is introduced into the renal pelvis. The wire is then removed and the distal end of the stent coiled in the bladder. This stent will protect the ureter for about 6 weeks while it heals.

A Foley catheter is maintained in the bladder for approximately 2 weeks, and the stent is maintained for approximately 6 weeks. Both the catheter and the stent can be removed in the office with cystoscopic guidance.

The diagnosis and treatment of ureteral injury
A gynecologic surgeon learns very early in his/her career to respect the ureter. Whether from the procedure being performed (endometriosis surgery, hysterectomy, myomectomy for ligamentous fibroids, salpingo-oophorectomy, excision of ovarian remnants, adhesiolysis), blood loss that obscures visualization and must be controlled, or use of energy for cutting, desiccation, and coagulation leading to potential lateral tissue damage, ureteral injury is a well-known complication. Even normal anatomic variations may put some women at greater risk; according to Hurd et al. (Am J Obstet Gynecol. 2001;184:336-9). In a small subset of women, the distance between the cervix and the ureter may be less than 0.5 cm.
As a practicing minimally invasive gynecologic surgeon for the past 30 years, and an early adapter to laparoscopic hysterectomy, I remember quite well the recommendation to always dissect out ureters at time of the procedure. At present, most will agree that selective dissection is safe and thus, more desirable, as bleeding, damage secondary to desiccation, and ureter devascularization with subsequent necrosis are all increased with ureterolysis.
I agree with Dr. Kenton and Dr. Mueller that ureteral stenting has not been shown to significantly decrease ureteral injury rates. Often times, with loss of peristalsis secondary to stent placement, locating the ureter may be even more difficult. Recent advances using lighted stents or indocyanine green, which fluoresces in response to near-infrared laser and can be injected into the ureter via the ureteral catheter tip, are still in the feasibility phase of evaluation and can be costly.
As most urogenital fistulae are secondary to unrecognized injuries at time of surgery, and due to the fact that intraoperative recognition of the injury allows for primary repair, thus, decreasing the rate of secondary surgery and the associated increased morbidity, I recommend cystoscopy to check for ureteral jets (ureteral efflux) be performed when there is concern regarding ureter compromise.
Currently, I utilize a 70° cystoscope to visualize the ureters. While in the past, I have used intravenous indigo carmine, methylene blue, or fluorescein sodium, I currently use Pyridium (phenazopyridine) 200 mg taken by mouth 1 hour prior to the procedure.
Unfortunately, ureteral jetting still may be noted despite partial ligation, laceration, or desiccation of the ureter.
If ureteral injury is not recognized at time of surgery, it can lead to various postoperative symptoms. If there is a ureteral defect, the patient may note profuse wound leakage, increased abdominal fluid, or a urinoma, ileus, fever, peritonitis, or hematuria. With ureteral obstruction, flank or abdominal pain or anuria can be noted; while, with fistula formation, the patient will likely present with urinary incontinence or watery vaginal discharge.

Conservative early approach likely best, RA expert says
SANDESTIN, FLA. – A conservative approach to early rheumatoid arthritis treatment has carried the day in the practice of Gerd R. Burmester, MD.
In a talk at the annual Congress of Clinical Rheumatology, Dr. Burmester said that, although there is room to argue for a more aggressive approach, with more intense treatment early, a less aggressive philosophy has worked well in his clinic.
Dr. Burmester, director of rheumatology and clinical immunology at Charite-University in Berlin and a past president of the European League Against Rheumatism (EULAR), said he drew inspiration from the results of the 2015 study CARE-RA, in which patients were treated with initial therapy of methotrexate plus sulfasalazine and a fairly high dose of 60 mg of prednisolone; methotrexate plus leflunomide plus 30 mg of prednisolone; or just methotrexate plus 30 mg of prednisolone that is quickly tapered down (Ann Rheum Dis. 2015 Jan;74[1]:27-34).
“Everyone would say, ‘Okay, this is quite easy – the more intensive drug regimen should give you better results,’ ” Dr. Burmester said. “But if you look at the data, there’s no difference.” And after just 8 weeks, the patients’ corticosteroid dose was down to 5 mg.
This, he said, “has changed my daily typical practice, quite a bit.”
“I start with, usually, 15 mg of methotrexate subcutaneously,” because of better efficacy and less liver toxicity than oral administration, he said, or an oral dose if a patient resists the subcutaneous administration or there is another reason to avoid it. “And I add 30 mg of prednisone and taper it down – 30, 20, 12.5 mg, and then down to 5 and eventually discontinued altogether.”
“This is an interesting scheme,” he said. “And this is exactly what I do with my patients.”
His approach might be worth noting not only for his leadership roles, but because of his fastidious approach to being a clinician – he said he still, personally, takes every patient’s 28-joint Disease Activity Score and Simple Disease Activity Index at every visit.
In a recent paper, he argued, along with prominent Canadian rheumatologist Janet Pope, both sides of the debate, for and against more aggressive treatment – methotrexate combined with conventional synthetic or biologic DMARDs – very early in the disease course (Lancet. 2017 Jun 10;389[10086]:2338-48).
“If you use a combination treatment with a biologic right away, what might be the advantages?” he said. “More patients would achieve rapid remission. It might result in long-term benefits, less joint damage, higher chance of reducing therapy in the future.”
On the other hand, he said, there are disadvantages.
“This is, of course, more expensive, if you use a biologic up front in early RA,” he said. “Not all patients of course need it, and some have also side effects.” He added that little time is lost if a treat-to-target principle is followed. Plus, patients tend to be more accepting of monotherapy than combination therapy at the start of treatment, and combination therapy might require more time spent in the clinic.
Data from German databases, dating back to 1997, show that far more patients are reaching remission today after several years of treatment (Z Rheumatol. 2017 Feb;76[1]:50-7). But, he added, “It’s not yet perfect. ... We still have quite a few patients who are in moderate disease activity” despite the availability of so many treatment options.
“There’s still, of course, a huge unmet need in this devastating disease if you don’t treat it correctly.”

SANDESTIN, FLA. – A conservative approach to early rheumatoid arthritis treatment has carried the day in the practice of Gerd R. Burmester, MD.
In a talk at the annual Congress of Clinical Rheumatology, Dr. Burmester said that, although there is room to argue for a more aggressive approach, with more intense treatment early, a less aggressive philosophy has worked well in his clinic.
Dr. Burmester, director of rheumatology and clinical immunology at Charite-University in Berlin and a past president of the European League Against Rheumatism (EULAR), said he drew inspiration from the results of the 2015 study CARE-RA, in which patients were treated with initial therapy of methotrexate plus sulfasalazine and a fairly high dose of 60 mg of prednisolone; methotrexate plus leflunomide plus 30 mg of prednisolone; or just methotrexate plus 30 mg of prednisolone that is quickly tapered down (Ann Rheum Dis. 2015 Jan;74[1]:27-34).
“Everyone would say, ‘Okay, this is quite easy – the more intensive drug regimen should give you better results,’ ” Dr. Burmester said. “But if you look at the data, there’s no difference.” And after just 8 weeks, the patients’ corticosteroid dose was down to 5 mg.
This, he said, “has changed my daily typical practice, quite a bit.”
“I start with, usually, 15 mg of methotrexate subcutaneously,” because of better efficacy and less liver toxicity than oral administration, he said, or an oral dose if a patient resists the subcutaneous administration or there is another reason to avoid it. “And I add 30 mg of prednisone and taper it down – 30, 20, 12.5 mg, and then down to 5 and eventually discontinued altogether.”
“This is an interesting scheme,” he said. “And this is exactly what I do with my patients.”
His approach might be worth noting not only for his leadership roles, but because of his fastidious approach to being a clinician – he said he still, personally, takes every patient’s 28-joint Disease Activity Score and Simple Disease Activity Index at every visit.
In a recent paper, he argued, along with prominent Canadian rheumatologist Janet Pope, both sides of the debate, for and against more aggressive treatment – methotrexate combined with conventional synthetic or biologic DMARDs – very early in the disease course (Lancet. 2017 Jun 10;389[10086]:2338-48).
“If you use a combination treatment with a biologic right away, what might be the advantages?” he said. “More patients would achieve rapid remission. It might result in long-term benefits, less joint damage, higher chance of reducing therapy in the future.”
On the other hand, he said, there are disadvantages.
