Urethral reconstruction for traumatic posterior urethral disruption: outcomes of a 25-year experience.
PurposeManagement of posterior urethral disruption due to pelvic trauma can be quite challenging and is the subject of ongoing controversy. This study presents an update of the University of California, San Francisco experience with delayed anastomotic posterior urethroplasty for management of these injuries.Materials and methodsSince 1979 all patients undergoing posterior urethroplasty by a single surgeon at University of California, San Francisco and its affiliated hospitals have been entered prospectively into a patient registry. For this cohort descriptive statistics were calculated and recurrence was analyzed with the Kaplan-Meier method. Success was defined as no recurrence (by symptoms and/or retrograde urethrogram) or a mild recurrence managed successfully with a single internal urethrotomy.ResultsA total of 134 male patients were analyzed with a mean of 32.9 and a median of 12 months followup. Mean patient age at surgery was 34.8 years. Of the patients 35% had undergone at least 1 prior procedure for stricture including prior urethroplasty in 16%. In addition, 22% required partial pubectomy and 4% a combined abdominal-perineal approach with total pubectomy. Of patients with a closed bladder neck on urethrography 34% vs 7% of those with an open bladder neck required pubectomy (p <0.001). Stricture length tended to be longer in pubectomy cases (mean 3.2 vs 2.1 cm by urethrography, p = 0.055). Of the patients 14% experienced recurrent stricture at a mean of 12 months, 42% of whom were treated successfully with a single urethrotomy. The overall success rate allowing 1 direct vision internal urethrotomy was 93%.ConclusionsAnastomotic urethroplasty offers excellent long-term results to patients with posterior urethral trauma and stricture disease even after multiple prior procedures

The "Fragile" Urethra as a Predictor of Early Artificial Urinary Sphincter Erosion.
ObjectivesTo identify predictors of early artificial sphincter (AUS) erosion among a cohort of men with erosion, who underwent AUS placement by either university or community-based surgeons.MethodsThe records of all patients with AUS erosions, including men who underwent AUS placement at outside facilities, were retrospectively reviewed. A Cox proportional-hazards model for time to erosion was performed with the predictors being the components of a fragile urethra (history of radiation, prior AUS, prior urethroplasty), androgen deprivation therapy (ADT), trans-corporal (TC), and 3.5 cm cuff, controlling for other risk factors. Kaplan-Meier survival curves and log-rank test compared "fragile" urethras with "not fragile" urethras. All statistical analysis was done using R version 3.5.2.ResultsOf the 156 men included, 36% had undergone AUS placement in the community. Median time to erosion was 16.0 months (1.0-240.0 months), and 122 (78%) met at least one fragility criteria. Radiation (HR 2.36, 95% CI 1.52-3.64) and prior urethroplasty (HR 2.12, 95% CI 1.18-3.80) were independently associated with earlier time to erosion. The Kaplan-Meier estimates demonstrate 1- and 5-year survival rates of 76.5% and 50.0%, respectively, for "non-fragile" and 44.1% and 14.8% for "fragile" urethras (P < .0001).ConclusionIn a diverse cohort of men with AUS erosion, men with "fragile" urethras eroded sooner. Radiation and prior urethroplasty were independent risk factors for earlier time to erosion, but prior AUS, ADT, TC and 3.5 cm cuff were not

Urinary and Sexual Function after Perineal Urethrostomy for Urethral Stricture Disease: An Analysis from the TURNS.
PurposePerineal urethrostomy is a viable option for many complex urethral strictures. However, to our knowledge no comparison with anterior urethroplasty regarding patient reported outcome measures has been published. We compared these groups using a large multi-institution database.Materials and methodsWe performed a retrospective study of anterior urethroplasty in the TURNS (Trauma and Urologic Reconstructive Network of Surgeons) database. The anterior urethroplasty cohort was defined by long strictures greater than 6 cm. We compared demographic, clinical, urinary and sexual characteristics using validated patient reported outcome measures between patients treated with long stricture anterior urethroplasty and those who underwent perineal urethrostomy.ResultsOf the 131 patients 92 treated with long stricture anterior urethroplasty and 39 treated with perineal urethrostomy met study inclusion criteria. The cumulative incidence of failure at 2 years was 30.2% (95% CI 18.3-47.3) for long stricture anterior urethroplasty and 14.5% (95% CI 4.8-39.1) for perineal urethrostomy (p = 0.09). Compared to baseline metrics, patients who underwent long stricture anterior urethroplasty and perineal urethrostomy had similar improvements in urinary function and stable sexual function after surgery.ConclusionsPatients reported improvement in urinary function after perineal urethrostomy with no deleterious effect on sexual function. These patient reported outcome measures were comparable to those of long stricture anterior urethroplasty. Perineal urethrostomy failure rates were similar to those of long stricture anterior urethroplasty

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

Association Between Ejaculatory Dysfunction and Post-Void Dribbling After Urethroplasty.
ObjectiveTo determine whether ejaculatory dysfunction (EjD) and post-void dribbling (PVD) after urethroplasty are associated, providing evidence for a common etiology.MethodsWe reviewed a prospectively maintained database for first-time, anterior urethroplasties. One item from the Male Sexual Health Questionnaire (MSHQ) assessed EjD: "How would you rate the strength or force of your ejaculation". One item from the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS-PROM) assessed PVD: "How often have you had slight wetting of your pants after you had finished urinating?". The frequency of symptoms was compared after penile vs. bulbar repairs, and anastomotic versus augmentation bulbar repairs. Associations were assessed with chi-square.ResultsA total of 728 men were included. Overall, postoperative EjD and PVD were common; 67% and 66%, respectively. There was a significant association between EjD and PVD for the whole cohort (p<0.0001); this association remained significant after penile repairs (p=0.01), bulbar repairs (p<0.0007), and bulbar anastomotic repairs (p=0.002), but not after bulbar augmentation repairs (p=0.052). EjD and PVD occurred at similar rates after penile and bulbar urethroplasty. The rate of EjD was similar after bulbar augmentation and bulbar anastomotic urethroplasties, but PVD was more common after bulbar augmentation (70% vs. 52%) (p = 0.0001).ConclusionEjD and PVD after anterior urethroplasty are significantly associated with one another, supporting the theory of a common etiology. High rates after penile repairs argue against a bulbospongiosus muscle damage etiology, and high rates after anastomotic repairs argue against graft sacculation. More work is needed to better understand and prevent symptoms

Minimizing Antibiotic Use in Urethral Reconstruction.
PurposeThere 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 methodsWe 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.ResultsThe 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.ConclusionsThe 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

Prevalence of Post-Micturition Incontinence before and after Anterior Urethroplasty.
PurposeIn this study we aimed to define the prevalence of preoperative and postoperative post-micturition incontinence or post-void dribbling after anterior urethroplasty for urethral stricture disease. We also sought to determine risk factors for its presence.Materials and methodsWe retrospectively reviewed a prospectively maintained, multi-institutional urethral stricture database to evaluate post-micturition incontinence using a single question from a validated questionnaire, "How often have you had a slight wetting of your pants a few minutes after you had finished urinating and had dressed yourself?" Possible answers were never-0 to all the time-3. The presence of post-micturition incontinence was defined as any answer greater than 0. Comparisons were made to stricture type and location, repair type and patient medical comorbidities.ResultsPreoperative and postoperative post-micturition incontinence questionnaires were completed by 614 and 331 patients, respectively. Patients without complete data available were excluded from study. Preoperative post-micturition incontinence was present in 73% of patients, of whom 44% stated that this symptom was present most of the time. Overall postoperative post-micturition incontinence was present in 40% of patients and again it was not predicted by stricture location or urethroplasty type. Of the 331 patients with followup questionnaires 60% reported improvement, 32% reported no change and 8% reported worsening symptoms. The overall rate of de novo post-micturition incontinence was low at 6.3%.ConclusionsThe prevalence of preoperative post-micturition incontinence is high and likely under reported. In most patients post-micturition incontinence improves after urethroplasty and the prevalence of de novo post-micturition incontinence is low. The presence of post-micturition incontinence was not predicted by stricture length or location, or urethroplasty repair type
