The Impact of Social Deprivation on Anterior Urethral Stricture Recurrence After Urethroplasty - A Trauma and Urologic Reconstructive Network of Surgeons (TURNS) Analysis.

INTRODUCTION AND OBJECTIVES: Several factors influence recurrence after urethral stricture repair. The impact of socioeconomic factors on stricture recurrence after urethroplasty is poorly understood. This study aims to assess the impact that social deprivation, an area-level measure of disadvantage, has on urethral stricture recurrence after urethroplasty. METHODS: We performed a retrospective review of patients undergoing urethral reconstruction by surgeons participating in a collaborative research group. Home zip code was used to calculate Social Deprivation Indices (SDI; 0-100), which quantifies the level of disadvantage across several sociodemographic domains collected in the American Community Survey. Patients without zip code data were excluded from the analysis. The Cox Proportional Hazards model was used to study the association between SDI and the hazard of functional recurrence, adjusting for stricture characteristics as well as age and body mass index. RESULTS: Median age was 46.0 years with a median follow up of 367 days for the 1452 men included in the study. Patients in the fourth SDI quartile (worst social deprivation) were more likely to be active smokers with traumatic and infectious strictures compared to the first SDI quartile. Patients in the fourth SDI quartile had 1.64 times the unadjusted hazard of functional stricture recurrence vs patients in the first SDI quartile (95% CI 1.04-2.59). Compared to anastomotic ± excision, substitution only repair had 1.90 times the unadjusted hazard of recurrence. The adjusted hazard of recurrence was 1.08 per 10-point increase in SDI (95% CI 1.01-1.15, P = .027). CONCLUSIONS: Patient social deprivation identifies those at higher risk for functional recurrence after anterior urethral stricture repair, offering an opportunity for preoperative counseling and postoperative surveillance. Addressing these social determinants of health can potentially improve outcomes in reconstructive surgery.

Grade V renal trauma management: results from the multi-institutional genito-urinary trauma study.

PURPOSE: To investigate management trends for American Association for the Surgery of Trauma (AAST) grade V renal trauma with focus on non-operative management. METHODS: We used prospectively collected data as part of the Multi-institutional Genito-Urinary Trauma Study (MiGUTS). We included patients with grade V renal trauma according to the AAST Injury Scoring Scale 2018 update. All cases submitted by participating centers with radiology images available were independently reviewed to confirm renal trauma grade. Management was classified as expectant, conservative (minimally invasive, endoscopic or percutaneous procedures), or operative (renal-related surgery). RESULTS: Eighty patients were included, 25 of whom had complete imaging and had independent confirmation of AAST grade V renal trauma. Median age was 35 years (Interquartile range (IQR) 25-50) and 23 (92%) had blunt trauma. Ten patients (40%) were managed operatively with nephrectomy. Conservative management was used in nine patients (36%) of which six received angioembolization and three had a stent or drainage tube placed. Expectant management was followed in six (24%) patients. Transfusion requirements were progressively higher with groups requiring more aggressive treatment, and injury characteristics differed significantly across management groups in terms of hematoma size and laceration size. Vascular contrast extravasation was more likely in operatively managed patients though a statistically significant association was not found. CONCLUSION: Successful use of nonoperative management for grade V injuries is used for a substantial subset of patients. Lower transfusion requirement and less severe injury radiologic phenotype appear to be important characteristics delineating this group.

Urethroscopic Findings following Urethroplasty Predict the Need for Secondary Intervention in the Long Term: A Multi-Institutional Study from Trauma and Urologic Reconstructive Network of Surgeons.

PURPOSE: Postoperative surveillance urethroscopy has been shown to be an effective tool to predict reoperation within 1 year after urethroplasty. We aimed to evaluate early surveillance urethroscopy findings and long-term outcomes among urethroplasty patients in order to define the value of surveillance urethroscopy to predict failure. MATERIALS AND METHODS: We evaluated 304 patients with at least 4 years of followup after urethroplasty performed at 10 institutions across the United States and Canada. All patients were surveilled using a flexible 17Fr cystoscope and were categorized into 3 groups: 1) normal lumen, 2) large-caliber stricture (≥17Fr) defined as the ability of the cystoscope to easily pass the narrowing and 3) small-caliber stricture (<17Fr) that the cystoscope could not be passed. Failure was stricture recurrence requiring a secondary intervention. RESULTS: The median followup time was 64.4 months (range 55.3-80.6) and the time to initial surveillance urethroscopy was 3.7 months (range 3.1-4.8) following urethroplasty. Secondary interventions were performed in 29 of 194 (15%) with normal lumens, 11 of 60 (18.3%) with ≥17Fr strictures and 32 of 50 (64%) with <17Fr strictures (p <0.001). The 1-, 3- and 9-year cumulative probability of intervention was 0.01, 0.06 and 0.23 for normal, 0.05, 0.17 and 0.18 for ≥17Fr, and 0.32, 0.50 and 0.73 for <17Fr lumen groups, respectively. Patient-reported outcome measures performed poorly to differentiate the 3 groups. CONCLUSIONS: Early cystoscopic visualization of scar recurrence that narrows the lumen to <17Fr following urethroplasty is a significant long-term predictor for patients who will eventually undergo a secondary intervention.

Minimizing Antibiotic Use in Urethral Reconstruction.

PURPOSE: There are no established guidelines regarding management of antibiotics for patients specifically undergoing urethral reconstruction. Our aim was to minimize antibiotic use by following a standardized protocol in the pre-, peri- and postoperative setting, and adhere to American Urological Association antibiotic guidelines. We hypothesized that prolonged suppressive antibiotics post-urethroplasty does not prevent urinary tract infection and/or wound infection rates. MATERIALS AND METHODS: We prospectively treated 900 patients undergoing urethroplasty or perineal urethrostomy at 11 centers over 2 years. The first-year cohort A received prolonged postoperative antibiotics. Year 2, cohort B, did not receive prolonged antibiotics. A standardized protocol following the American Urological Association guidelines for perioperative antibiotics was used. The 30-day postoperative infectious complications were determined. We used chi-square analysis to compare the cohorts, and multivariate logistic regression to identify risk factors. RESULTS: The mean age of participants in both cohorts was 49.7 years old and the average stricture length was 4.09 cm. Overall, the rate of postoperative urinary tract infection and wound infection within 30 days was 5.1% (6.7% in phase 1 vs 3.9% in phase 2, p=0.064) and 3.9% (4.1% in phase 1 vs 3.7% in phase 2, p=0.772), respectively. Multivariate logistic regression analysis of patient characteristics and operative factors did not reveal any factors predictive of postoperative infections. CONCLUSIONS: The use of a standardized protocol minimized antibiotic use and demonstrated no benefit to prolonged antibiotic use. There were no identifiable risk factors when considering surgical characteristics. Given the concern of antibiotic over-prescription, we do not recommend prolonged antibiotic use after urethral reconstruction.

Defining Success after Anterior Urethroplasty: An Argument for a Universal Definition and Surveillance Protocol.

PURPOSE: A successful urethroplasty has been defined in different ways across studies. This variety in the literature makes it difficult to compare success rates and techniques across studies. We aim to evaluate the success of anterior urethroplasty based on different definitions of success in a single cohort. MATERIALS AND METHODS: Data were collected from a multi-institutional, prospectively maintained database. We included men undergoing first-time, single-stage, anterior urethroplasty between 2006 and 2020. Exclusion criteria included lack of followup, hypospadias, extended meatotomy, perineal urethrostomy, posterior urethroplasty and staged repairs. We compared 5 different ways to define a "failed" urethroplasty: 1) stricture retreatment, 2) anatomical recurrence on cystoscopy, 3) peak flow rate <15 ml/second, 4) weak stream on questionnaire and 5) failure by any of these measures. Kaplan-Meier survival curves were generated for each of the definitions. We also compared outcomes by stricture length, location and etiology. RESULTS: A total of 712 men met inclusion criteria, including completion of all types of followup. The 1- and 5-year estimated probabilities of success were "retreatment," 94% and 75%; "cystoscopy," 88% and 71%; "uroflow," 84% and 58%; "questionnaire," 67% and 37%; and "any failure," 57% and 23%. This pattern was inconsistent across stricture length, location and etiology. CONCLUSIONS: The estimated probability of success after first-time, anterior urethroplasty is highly dependent on the way success is defined. The variability in definitions in the literature has limited our ability to compare urethroplasty outcomes across studies.

Urotrauma Guideline 2020: AUA Guideline.

PURPOSE: The authors of this guideline reviewed the urologic trauma literature to guide clinicians in the appropriate methods of evaluation and management of genitourinary injuries. MATERIALS AND METHODS: The Panel amended the Guideline in 2020 to reflect additional literature published through February 2020. When sufficient evidence existed, the Panel assigned the body of evidence a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, the Panel provided additional information as Clinical Principles and Expert Opinions (See table 1[Table: see text]). RESULTS: The Panel updated a total of six existing statements on renal, ureteral, bladder, urethra, and genital trauma. Additionally, four new statements were added based on literature released since the 2017 amendment. Statement 5b was added based on new evidence for treatment of hemodynamically unstable patients with renal trauma. Statement 20b was added based on new literature for percutaneous or open suprapubic tube placement following pelvic fracture urethral injury. Statements 30a and 30b were also added to provide guidance on ultrasonography for blunt scrotal injuries suggestive of testicular rupture and for performing surgical exploration with repair or orchiectomy for penetrating scrotal injuries respectively. CONCLUSIONS: These evidence-based updates to the AUA Guidelines further inform the treatment of urotrauma.

The American Association for the Surgery of Trauma Renal Grading System-Should Segmental Kidney Infarction be Classified as a Grade IV Injury?

PURPOSE: In 2018 the American Association for the Surgery of Trauma revised renal injury grading. One change was inclusion of segmental kidney infarction under grade IV injuries. We aimed to assess how segmental kidney infarction will change the scope of grade IV injuries and compare bleeding control interventions in those with and without isolated segmental kidney infarction. METHODS: We used high grade renal trauma data from 7 level 1 trauma centers from 2013 to 2018 as part of the Multi-institutional Genito-Urinary Trauma Study. Initial computerized tomography scans were reviewed to regrade the injuries. Injuries were categorized as isolated segmental kidney infarction if segmental parenchymal infarction was the only reason for inclusion under grade IV injury. All other grade IV injuries (including combined injury patterns) were categorized as without isolated segmental kidney infarction. Bleeding interventions were compared between those with and without isolated segmental kidney infarction. RESULTS: From 550 patients with high grade renal trauma and available computerized tomography, 250 (45%) were grade IV according to the 2018 American Association for the Surgery of Trauma grading system. Of these, 121 (48%) had isolated segmental kidney infarction. The majority of patients with isolated segmental kidney infarction (88%) would have been assigned a lower grade using the original 1989 grading system. Rate of bleeding control interventions was lower in isolated segmental kidney infarction compared to other grade IV injuries (7% vs 21%, p=0.002). Downgrading all patients with isolated segmental kidney infarction to grade III did not change the grading system's associations with bleeding interventions. CONCLUSIONS: Approximately half of the 2018 American Association for the Surgery of Trauma grade IV injuries have isolated segmental kidney infarction. Including isolated segmental kidney infarction in grade IV injuries increases the heterogeneity of these injuries without increasing the grading system's ability to predict bleeding interventions. In future iterations of the American Association for the Surgery of Trauma renal trauma grading isolated segmental kidney infarction could be reclassified as grade III injury.

Outcomes and Risk Factors of Revision and Replacement Artificial Urinary Sphincter Implantation in Radiated and Nonradiated Cases.

PURPOSE: Risk factors for complications after artificial urinary sphincter surgery include a history of pelvic radiation and prior artificial urinary sphincter complication. The survival of a second artificial urinary sphincter in the setting of prior device complication and radiation is not well described. We report the survival of redo artificial urinary sphincter surgery and identify risk factors for repeat complications. MATERIALS AND METHODS: A multi-institutional database was queried for redo artificial urinary sphincter surgeries. The primary outcome was median survival of a second and third artificial urinary sphincter in radiated and nonradiated cases. A Cox proportional hazards survival analysis was performed to identify additional patient and surgery risk factors. RESULTS: Median time to explantation of the initial artificial urinary sphincter in radiated (150) and nonradiated (174) cases was 26.4 and 35.6 months, respectively (p=0.043). For a second device median time to explantation was 30.1 and 38.7 months (p=0.034) and for a third device it was 28.5 and 30.6 months (p=0.020), respectively. The 5-year revision-free survival for patients undergoing a second artificial urinary sphincter surgery with no risk factors, history of radiation, history of urethroplasty, and history of radiation and urethroplasty were 83.1%, 72.6%, 63.9% and 46%, respectively. CONCLUSIONS: Patients without additional risk factors undergoing second and third artificial urinary sphincter surgeries experience revision-free rates similar to those of their initial artificial urinary sphincter devices. Patients who have been treated with pelvic radiation have earlier artificial urinary sphincter complications. When multiple risk factors exist, revision-free rates decrease significantly.

Current Management of Extraperitoneal Bladder Injuries: Results from the Multi-Institutional Genito-Urinary Trauma Study (MiGUTS).

PURPOSE: We studied the current management trends for extraperitoneal bladder injuries and evaluated the use of operative repair versus catheter drainage, and the associated complications with each approach. MATERIALS AND METHODS: We prospectively collected data on bladder trauma from 20 level 1 trauma centers across the United States from 2013 to 2018. We excluded patients with intraperitoneal bladder injury and those who died within 24 hours of hospital arrival. We separated patients with extraperitoneal bladder injuries into 2 groups (catheter drainage vs operative repair) based on their initial management within the first 4 days and compared the rates of bladder injury related complications among them. Regression analyses were used to identify potential predictors of complications. RESULTS: From 323 bladder injuries we included 157 patients with extraperitoneal bladder injuries. Concomitant injuries occurred in 139 (88%) patients with pelvic fracture seen in 79%. Sixty-seven patients (43%) initially underwent operative repair for their extraperitoneal bladder injuries. The 3 most common reasons for operative repair were severity of injury or bladder neck injury (40%), injury found during laparotomy (39%) and concern for pelvic hardware contamination (28%). Significant complications were identified in 23% and 19% of the catheter drainage and operative repair groups, respectively (p=0.55). The only statistically significant predictor for complications was bladder neck or urethral injury (RR 2.69, 95% 1.21-5.97, p=0.01). CONCLUSIONS: In this large multi-institutional cohort, 43% of patients underwent surgical repair for initial management of extraperitoneal bladder injuries. We found no significant difference in complications between the initial management strategies of catheter drainage and operative repair. The most significant predictor for complications was concomitant urethral or bladder neck injury.

A Retrospective Cohort Study Evaluating Surgical Aptitude Over Time in a New Male-To-Female Penoscrotal Vaginoplasty Program.

BACKGROUND: Given the burgeoning demand for gender affirmation surgery, there are few studies examining both surgical process variables and patient outcome variables. Knowing the learning curve for surgical teams who are beginning to perform this procedure will be important for patient safety and presurgical patient counseling as more institutions open transgender surgical programs. AIM: The purpose of this study was to determine the demographics of patients pursuing penoscrotal vaginoplasty, to determine their postoperative course, and to determine a learning curve for the surgical team performing penoscrotal vaginoplasty. METHODS: We retrospectively reviewed charts of all 43 patients who underwent penoscrotal vaginoplasty from the commencement of a new male-to-female penoscrotal vaginoplasty program in March 2018 through July 2019. OUTCOMES: Primary outcomes included mean hemoglobin decrease from surgery and operative time. Mean time to neoclitoral sensation, length of hospital admission, complication rates, reoperation rates, length of narcotic use after surgery, and demographics were also evaluated. Associations between surgical team experience and outcomes were assessed with Spearman's rho and Cox regression, and curve-fitting procedures were applied to determine the relationship. RESULTS: The mean operative time from initial incision to procedure finish was 225 minutes, and the mean decrease in hemoglobin was 3.3 g/dL. The mean time to neoclitoral sensation was 0.72 months. The time until neoclitoral sensation decreased as the surgical cases performed increased (Spearman's rho, -0.577 [P < .001]), with a power function best describing the learning curve. Operative time did not change with case number (Spearman's rho, 0.062 [P = .698]) but overall time in the operating room did (Spearman's rho, 0.631 [P < .001]). Mean length of hospital admission was 2.9 days. There were no intraoperative complications. 18 patients (42%) experienced a postoperative complication. 8 of 43 patients underwent reoperation (20%). Narcotics were used a mean of 9.5 days after surgery. CLINICAL IMPLICATIONS: A learning curve can be demonstrated in penoscrotal vaginoplasty for time to neoclitoral sensation and overall time in the operating room, plateauing between 30 and 40 cases. STRENGTHS AND LIMITATIONS: Strengths include assessing a learning curve for time to neoclitoral sensation, length of hospital stay, and length of postoperative narcotic use after penoscrotal vaginoplasty, which, to our knowledge, has not been reported elsewhere. Limitations include our overall low number of patients. CONCLUSION: Despite a low number of cases, length of hospital stay was short and the postoperative complication rate was similar to that of long-standing penoscrotal vaginoplasty programs.

Prior Radiation Therapy Decreases Time to Idiopathic Erosion of Artificial Urinary Sphincter: A Multi-Institutional Analysis.

PURPOSE: Substantial controversy and conflicting data exist regarding the survival of the artificial urinary sphincter in patients with prior radiation therapy. We present data from a multi-institutional analysis examining the effect of prior radiation for prostate cancer on device survival. MATERIALS AND METHODS: A database was compiled of patients with artificial urinary sphincter cuff erosion, which included demographic and comorbid patient characteristics, functional analyses and interventions. We identified 80 patients with iatrogenic or idiopathic artificial urinary sphincter erosion. Idiopathic erosion cases were further analyzed to determine factors influencing device survival with specific stratification for radiation therapy. RESULTS: A total of 56 patients were identified with idiopathic artificial urinary sphincter erosion. Of those men 33 (58.9%) had not undergone radiation treatment while 23 (41.1%) had a history of brachytherapy or external beam radiotherapy. In patients without radiation erosion-free median device survival was 3.15 years (95% CI 1.95-5.80), in contrast to the median device survival of only 1.00 year (95% CI 0.36-3.00) in irradiated patients. The erosion-free survival experience of patients with vs without radiation differed significantly (Wilcoxon-Breslow test for equality of survivor functions p = 0.03). CONCLUSIONS: Radiation therapy in patients with known idiopathic cuff erosion in this contemporary analysis correlated with significantly increased time to erosion. Mean time to idiopathic cuff erosion was accelerated by approximately 2 years in irradiated cases. To our knowledge these data represent the first demonstration of substantial outcome differences associated with radiation in patients with an artificial urinary sphincter who present specifically with cuff erosion.

Impact of Radiation and Transcorporeal Artificial Sphincter Placement in Patients with Prior Urethral Cuff Erosion: Results from a Retrospective Multicenter Analysis.

PURPOSE: Many providers elect to use a transcorporeal approach for artificial urinary sphincter placement in an attempt to minimize risks, given the increased risk of complications in revision cases. We present outcomes in a multicenter retrospective analysis of artificial urinary sphincter cuff reimplantation in patients with prior cuff erosion with special consideration given to the transcorporeal approach. MATERIALS AND METHODS: We compiled a multi-institutional database of patients who underwent artificial urinary sphincter reimplantation after prior urethral erosion. Of the 34 identified patients 24 underwent transcorporeal cuff replacement. Patients with transcorporeal cuff replacement were further analyzed with specific stratification for radiation therapy. RESULTS: The rate of subsequent complications after eroded cuff reimplantation was 32.4% (11 of 34 patients). The most frequent complication was recurrent erosion, which developed in 9 of the 34 patients (26.4%). Repeat artificial urinary sphincter complications developed more frequently in patients with history of radiation compared to nonirradiated patients (8 of 16 or 50% vs 3 of 18 or 16.7%). However, this difference was not statistically significant (p = 0.066). The transcorporeal technique was applied in 24 of 33 patients (70.5%) and relative to the nontranscorporeal group there was no difference in the complication rate (p = 0.438). On subgroup analysis of the transcorporeal group there was a higher rate of repeat complications in irradiated patients (p = 0.006). CONCLUSIONS: These data suggest that transcorporeal cuff reimplantation may not decrease the incidence of repeat complications after prior cuff erosion. However, radiation therapy is associated with a worse outcome even when transcorporeal cuff placement is performed.

Urethral lichen sclerosus under the microscope: a survey of academic pathologists.

INTRODUCTION: Given the poor understanding of the pathophysiology of genital lichen sclerosus (GLS) and a lack of accepted definitive diagnostic criteria, we proposed to survey pathologists regarding their understanding of GLS. We hypothesized that significant disagreement about GLS will exist. MATERIALS AND METHODS: All urologists participating in the Trauma and Urologic Reconstruction Network of Surgeons identified genitourinary (GUP) and dermatopathologists (DP) at their respective institutions who were then invited to participate in an online survey regarding their experience with diagnosing GLS, GLS pathophysiology and its relationship to urethral stricture disease. RESULTS: There were 23 (12 DP, 11 GUP) pathologists that completed the survey. The most agreed upon criteria for diagnosis were dermal collagen homogenization (85.7%), loss of the normal rete pattern (33.3%) and atrophic epidermis (28.5%). No pathologists believed GLS had an infectious etiology (19% maybe, 42% unknown) and 19% believed GLS to be an autoimmune disorder (42% maybe, 38% unknown); 19% believed LS to be premalignant, but 52% believed it was associated with cancer; 80% believed that LS could involve the urethra (DP (92%) versus GUP (67%); p = 0.272). Of those diagnosing urethral GLS, 80% of DUP believed that GLS must first involve the glans/prepuce before involving the urethra, while all GUP believed that urethral disease could exist in isolation (p = 0.007). CONCLUSIONS: There was significant disagreement in this specialized cohort of pathologists when diagnosing GLS. A logical first step appears to be improving agreement on how to best describe and classify the disease. This may lead to improve treatments.

Urinary Diversion for Severe Urinary Adverse Events of Prostate Radiation: Results from a Multi-Institutional Study.

PURPOSE: We evaluated the short and long-term surgical outcomes of urinary diversion done for urinary adverse events arising from prostate radiation therapy. We hypothesized that patient characteristics are associated with complications after urinary diversion. MATERIALS AND METHODS: We performed a retrospective cohort study of 100 men who underwent urinary diversion (urinary conduit or continent catheterizable pouch) due to urinary adverse events after prostate radiotherapy from 2007 to 2016 from 9 academic centers in the United States. Outcome measurements included predictors of short and long-term complications, and readmission after urinary diversion of patients who had prostate cancer treated with radiotherapy. The data were summarized using descriptive statistics and univariate associations with complications were identified with logistic regression controlling for center. RESULTS: Mean patient age was 71 years and median time from radiotherapy to urinary diversion was 8 years. Overall 81 (81%) patients had combined modality therapy (radical prostatectomy plus radiotherapy or various combinations of radiotherapy). Grade 3a or greater Clavien-Dindo complications occurred in 31 (35%) men, including 4 deaths (4.5%). Normal weight men had more short-term complications compared to overweight (OR 4.9, 95% CI 1.3-23.1, p=0.02) and obese men (OR 6.3, 95% CI 1.6-31.1, p=0.009). Hospital readmission within 6 weeks of surgery occurred for 35 (38%) men. Surgery was needed to treat long-term complications after urinary diversion in 19 (22%) patients with a median followup of 16.3 months. CONCLUSIONS: Urinary diversion after prostate radiotherapy has a considerable short and long-term surgical complication rate. Urinary diversion most often cannot be avoided in these patients but appreciation of the risks allows for informed shared decision making between surgeons and patients.

Radiation-induced complex anterior urinary fistulation for prostate cancer: a retrospective multicenter study from the Trauma and Urologic Reconstruction Network of Surgeons (TURNS).

PURPOSE: To characterize anterior urinary fistulae following radiotherapy for prostate cancer. METHODS: Over 10 years, 31 men were identified to have an anterior urinary fistula. A retrospective database was created to evaluate patient demographics, presentation, diagnostic procedures, operative interventions, outcomes, and complications. Comparisons between men who underwent cystectomy versus bladder-sparing surgeries were performed. RESULTS: At a median age of 73 (interquartile range (IQR) 68.5, 79) years, presenting symptoms included as follows: pubic pain (19/31, 61%), urine drainage via fistula (10/31, 32%), or a superficial wound infection (6/31, 19%). Recent instrumentation prior to diagnosis of anterior urinary fistula was reported by 18/31 (58%) at a median of 14.9 months (IQR 7.9, 103.8) after manipulation. Anterior fistula formation was either isolated to the pubic symphysis (19/31, 61%) or the thigh (12/31, 38%). Nineteen men underwent a cystectomy, whereas 12 men underwent a fistula repair. Excluding grades 1 and 2, 30- and 90-day postoperative complications were limited to four and two men, respectively, all of whom had a grade 3 complication. At 6-month follow-up, 26/31 (84%) men reported their pain had resolved. There was one fistula recurrence managed with subsequent cystectomy. CONCLUSIONS: Complex anterior urinary fistulae to the pubic symphysis and thigh are devastating yet treatable conditions. Universally, these men have a history of radiotherapy and repeated endoscopic interventions. Surgical intervention with either cystectomy or primary repair was highly successful.

Understanding the Relationship between Chronic Systemic Disease and Lichen Sclerosus Urethral Strictures.

PURPOSE: Lichen sclerosus is a chronic, inflammatory skin condition of the genitalia of unknown origin that accounts for nearly 10% of urethral stricture disease. In this study we determine systemic comorbidities associated with lichen sclerosus in men. MATERIALS AND METHODS: We analyzed data from 1,151 men who were enrolled in a multi-institutional prospective urethroplasty outcomes database. Individuals were grouped by stricture etiology, and baseline demographics, medical histories and patient reported outcome measures were retrospectively compared across groups. RESULTS: Of the 1,151 men in the database 81 (7.0%) were noted to have lichen sclerosus related urethral stricture disease. Average patient age was 46.06 ± 16.52 years, with those with lichen sclerosus being significantly older than those without lichen sclerosus (51.26 ± 13.84 vs 45.68 ± 16.64, p = 0.0011). Men with lichen sclerosus were more likely to have hypertension, hyperlipidemia and diabetes, and to use tobacco products. Controlling for age, men with lichen sclerosus related urethral stricture disease had a higher body mass index (aOR 1.089, 95% CI 1.050-1.130), and were more likely to have hypertension (aOR 2.028, 1.21-3.41) and be active tobacco users (aOR 2.0, 1.36-3.40). Mean preoperative patient reported outcome measures scores for urinary and sexual function were similar. Controlling for stricture length and location, the adjusted odds of surgical failure were higher for lichen sclerosus related urethral stricture disease (aOR 1.9, 95% CI 0.9-4.2). CONCLUSIONS: Lichen sclerosus related urethral stricture disease is associated with chronic systemic diseases. This association may implicate a systemic inflammatory and/or autoimmune pathophysiology. A 2-hit mechanism implicating local and systemic factors for lichen sclerosus related urethral stricture disease development and progression is hypothesized.

Genitourinary trauma in geriatric patients.

PURPOSE OF REVIEW: The geriatric population is the fastest growing segment of the population, and geriatric trauma patients are increasingly common. Caring for this population has unique challenges. The goal of the review is to identify factors that may help in the care of geriatric patients suffering from genitourinary trauma. RECENT FINDINGS: Multiple factors lead to inferior outcomes in patients with geriatric trauma including failure to rescue, treatment in lower volume trauma centers, and undertriage of geriatric patients. Improvement in geriatric trauma outcomes occurs with the use of dedicated geriatric consult teams. The surgical management of genitourinary injuries in the geriatric population remains unchanged. SUMMARY: Interventions for geriatric patients differ from younger populations. Direct changes in overall management of the geriatric population lead to improved outcomes. The treatment of geriatric trauma patients with genitourinary injuries is similar to a younger cohort. The lack of recent studies in clinical outcomes in this population has been identified as a gap in knowledge that will require future research to answer.

Intralesional injection of mitomycin C at transurethral incision of bladder neck contracture may offer limited benefit: TURNS Study Group.

PURPOSE: Injection of mitomycin C may increase the success of transurethral incision of the bladder neck for the treatment of bladder neck contracture. We evaluated the efficacy of mitomycin C injection across multiple institutions. MATERIALS AND METHODS: Data on all patients who underwent transurethral incision of the bladder neck with mitomycin C from 2009 to 2014 were retrospectively reviewed from 6 centers in the TURNS. Patients with at least 3 months of cystoscopic followup were included in the analysis. RESULTS: A total of 66 patients underwent transurethral incision of the bladder neck with mitomycin C and 55 meeting the study inclusion criteria were analyzed. Mean ± SD patient age was 64 ± 7.6 years. Dilation or prior transurethral incision of the bladder neck failed in 80% (44 of 55) of patients. Overall 58% (32 of 55) of patients achieved resolution of bladder neck contracture after 1 transurethral incision of the bladder neck with mitomycin C at a median followup of 9.2 months (IQR 11.7). There were 23 patients who had recurrence at a median of 3.7 months (IQR 4.2), 15 who underwent repeat transurethral incision of the bladder neck with mitomycin C and 9 of 15 (60%) who were free of another recurrence at a median of 8.6 months (IQR 8.8), for an overall success rate of 75% (41 of 55). Incision with electrocautery (Collins knife) was predictive of success compared with cold knife incision (63% vs 50%, p=0.03). Four patients experienced serious adverse events related to mitomycin C and 3 needed or are planning cystectomy. CONCLUSIONS: The efficacy of intralesional injection of mitomycin C at transurethral incision of the bladder neck was lower than previously reported and was associated with a 7% rate of serious adverse events.

Urotrauma: AUA guideline.

PURPOSE: The authors of this guideline reviewed the urologic trauma literature to guide clinicians in the appropriate methods of evaluation and management of genitourinary injuries. MATERIALS AND METHODS: A systematic review of the literature using the MEDLINE® and EMBASE databases (search dates 1/1/90-9/19/12) was conducted to identify peer-reviewed publications relevant to urotrauma. The review yielded an evidence base of 372 studies after application of inclusion/exclusion criteria. These publications were used to inform the statements presented in the guideline as Standards, Recommendations or Options. When sufficient evidence existed, the body of evidence for a particular treatment was assigned a strength rating of A (high), B (moderate) or C (low). In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. RESULTS: Guideline statements were created to inform clinicians on the initial observation, evaluation and subsequent management of renal, ureteral, bladder, urethral and genital traumatic injuries. CONCLUSIONS: Genitourinary organ salvage has become increasingly possible as a result of advances in imaging, minimally invasive techniques, and reconstructive surgery. As the field of genitourinary reconstruction continues to evolve, clinicians must strive to approach clinical problems in a creative, multidisciplinary, evidence-based manner to ensure optimal outcomes.
