Multicenter analysis of posterior urethroplasty complexity and outcomes following pelvic fracture urethral injury.

PURPOSE: To analyze outcomes of posterior urethroplasty following pelvic fracture urethral injuries (PFUI) and to determine risk factors for surgical complexity and success. METHODS: Patients who underwent posterior urethroplasty following PFUI were identified in the Trauma and Urologic Reconstructive Network of Surgeons (TURNS) database. Demographics, injury patterns, management strategies, and prior interventions were evaluated. Risk factors for surgical failure and the impact of ancillary urethral lengthening maneuvers (corporal splitting, pubectomy and supracrural rerouting) were evaluated. RESULTS: Of the 436 posterior urethroplasties identified, 122 were following PFUI. 83 (68%) patients were acutely managed with suprapubic tubes, while 39 (32%) underwent early endoscopic realignment. 16 (13%) patients underwent pelvic artery embolization in the acute setting. 116 cases (95%) were completed via a perineal approach, while 6 (5%) were performed via an abdominoperineal approach. The need for one or more ancillary maneuvers to gain urethral length occurred in 4 (36%) patients. Of these, 44 (36%) received corporal splitting, 16 (13%) partial or complete pubectomy, and 2 (2%) supracrural rerouting. Younger patients, those with longer distraction defects, and those with a history of angioembolization were more likely to require ancillary maneuvers. 111 patients (91%) did not require repeat intervention during follow-up. Angioembolization (p = 0.03) and longer distraction defects (p = 0.01) were associated with failure. CONCLUSIONS: Posterior urethroplasty provides excellent success rates for patients following PFUI. Pelvic angioembolization and increased defect length are associated with increased surgical complexity and risk of failure. Surgeons should be prepared to implement ancillary maneuvers when indicated to achieve a tension-free anastomosis.

Robotic Davydov Peritoneal Flap Vaginoplasty for Augmentation of Vaginal Depth in Feminizing Vaginoplasty.

PURPOSE: Penile inversion vaginoplasty is the most common procedure for genital reconstruction in transwomen. While penile inversion vaginoplasty usually provides an excellent aesthetic result, the technique may be complicated by vaginal stenosis and inadequate depth, especially in transwomen with limited penile and scrotal tissue. We describe a technique of using peritoneal flaps to augment the neovaginal apex and canal in penile inversion vaginoplasty for transwomen. MATERIALS AND METHODS: Between 2017 and 2018 we identified 41 transwomen who underwent primary penile inversion and peritoneal flap vaginoplasty. Two approximately 6 cm wide by 8 cm long peritoneal flaps were raised from the anterior aspect of the rectum and the sigmoid colon, and the posterior aspect of the bladder to create the apex of the neovagina. RESULTS: Average ± SD age of the 41 patients was 34 ± 14 years. Average procedure duration was 262 ± 35 minutes and average length of stay was 5 days. Average followup was 114 ± 79 days. At the most recent followup vaginal depth and width were measured to be 14.2 ± 0.7 and 3.6 ± 0.2 cm, respectively. The peritoneal flap added an additional 5 cm of depth beyond the length of the skin graft, forming the vaginal canal in patients with limited scrotal skin. CONCLUSIONS: Penile inversion vaginoplasty remains the gold standard for primary genital reconstruction in transwomen. Peritoneal flaps provide an alternative technique for increased neovaginal depth, creating a well vascularized apex with acceptable anticipated complications.

Multi-Institutional Outcomes of Minimally Invasive Harvest of Rectal Mucosa Graft for Anterior Urethral Reconstruction.

PURPOSE: We report multi-institutional outcomes in patients who underwent urethroplasty with a rectal mucosa graft. MATERIALS AND METHODS: We used the TURNS (Trauma and Urologic Reconstructive Network of Surgeons) database to identify patients who underwent urethral reconstruction with transanal harvest of a rectal mucosa graft. We reviewed preoperative demographics, stricture etiology, previous management and patient outcomes. RESULTS: We identified 13 patients from April 2013 to June 2017. Median age at surgery was 54 years. The stricture etiology was lichen sclerosus in 6 of 13 patients (46%), idiopathic in 2 (15%), hypospadias in 1 (7%), prior gender confirming surgery in 3 (23%) and rectourethral fistula after radiation for prostate cancer in 1 (7%). Prior procedures included failed urethroplasty with a buccal mucosa graft in 9 of 13 patients (69%), direct vision internal urethrotomy in 2 (15%) and none in 2 (15%). Median stricture length was 13 cm. Stricture location in the 9 cisgender patients was panurethral in 5 (56%), bulbopendulous in 2 (22%) and bulbar in 2 (22%). It was located at the junction of the fixed urethra extending into the neophallus in all 3 patients (100%) who underwent prior gender confirming surgery. Mean rectal mucosa graft length for urethroplasty was 10.6 cm (range 3 to 16). Repair types included dorsal or ventral onlay, or 2-stage repair. Stricture recurred at a median followup of 13.5 months in 2 of 13 patients (15%). Postoperative complications included glans dehiscence, urethrocutaneous fistula and compartment syndrome in 1 patient each (7%). No rectal or bowel related complications were reported. CONCLUSIONS: Urethral reconstruction with a transanal harvested rectal mucosa graft is a safe technique when a buccal mucosa graft is unavailable or not indicated.

Contemporary analysis of management of isolated pendulous urethral strictures using pedicled skin flap urethroplasty repair.

OBJECTIVES: To evaluate contemporary outcomes of urethroplasty employing a pedicled skin flap for isolated pendulous urethral strictures. SUBJECTS/PATIENTS: Inclusion of males > 18 years of age with isolated pendulous urethral strictures treated between 1996 and 2012. RESULTS: A total of 81 patients with isolated pendulous urethral stricture were identified. Twenty-eight patients underwent repair with a pedicled skin flap during the study period. The median age of the patients treated with a pedicled skin flap was 47 years old (range 21-74). The etiology of the strictures was considered to be idiopathic in 10 patients (35.7%), iatrogenic in 9 patients (32.1%), as a complication of prior hypospadias repair in 6 patients (21.4%), infectious in 2 patients (7.1%), and traumatic in 1 patient (3.6%). The median follow-up was 27 months (range 1-214). Urethroplasty success was noted in 19/21 patients (90.5%). Urethral stricture recurrence occurred in 2 of the 21 patients (9.5%). CONCLUSIONS: The pedicled skin flap repair for pendulous urethral strictures remains a durable and safe technique in patients without LS.

A Critical Analysis of Bulbar Urethroplasty Stricture Recurrence: Characteristics and Management.

PURPOSE: We evaluated the management of recurrent bulbar urethral stricture disease after urethroplasty at our institution. MATERIALS AND METHODS: We performed an institution review board approved, retrospective case study of our urethroplasty database to collect stricture related and postoperative information with an emphasis on bulbar urethral stricture disease recurrence after urethroplasty between 1996 and 2012. Repair types included primary anastomotic, augmented anastomotic and onlay repair. Recurrence, which was defined as the need for intervention, was diagnosed with cystoscopy or retrograde urethrogram. RESULTS: We identified 437 men who underwent urethroplasty of bulbar urethral stricture disease as performed by 2 surgeons from January 1996 to December 2012. Of the men 395 had available followup data. Recurrence was identified in 25 men (6.3%), of whom all presented with symptoms, including a weak stream in 23, urinary tract infection in 1 and pyelonephritis in 1. Median time to recurrence was 10 months. Recurrence was initially treated endoscopically in 23 of 25 cases (92%), dilatation in 12 and visual urethrotomy in 11. In 5 patients (22%) further recurrence developed after endoscopic treatment, which was managed by repeat urethroplasty in 2, self-calibration only in 2 and visual urethrotomy with subsequent self-calibration in 1. We identified 2 distinct phenotypes of recurrent stricture, including type A-short focal recurrence, which may be salvaged with an endoscopic procedure, and type B-the long graft length type, which is less likely to be salvaged with endoscopy. CONCLUSIONS: Recurrence after urethroplasty is most likely to develop within the first 12 months. Type A short focal recurrence may be managed by a salvage endoscopic procedure, including dilation or visual urethrotomy. These data on the phenotype of recurrence may be useful for patient treatment.

Survey on the Contemporary Management of Intraoperative Urethral Injuries During Penile Prosthesis Implantation.

BACKGROUND: Intraoperative urethral injury is an uncommon event during the placement of a penile prosthesis, and alternative management strategies have been proposed with continuation of implantation after urethral injury. AIM: To evaluate surgeon practices in the management of intraoperative urethral injury. METHODS: An online survey was sent to the society listservs of the Genitourinary Reconstructive Surgeons (GURS) and the Sexual Medicine Society of North America (SMSNA). Physicians were queried on their fellowship training, experience with penile prosthesis implantation, and management of urethral injuries during prosthesis placement. The response data were analyzed using SAS 9.4 (SAS Institute, Cary, NC, USA). The χ2 test and Fisher exact test were used to determine associations between variables. OUTCOMES: Survey responses. RESULTS: 131 survey responses were analyzed. Of the responders, 41.2% were GURS fellowship trained, 19.1% were SMSNA trained, 30.5% were non-fellowship trained, and 9.2% were trained in other fellowships. 25.4% of participants performed more than 50 implantations per year, 37.7% performed 20 to 50 per year, and 36.9% performed fewer than 20 per year. Urethral injury during prosthesis implantation was uncommon, with 26.2% reporting 0 injury, 58.5% reporting 1 to 3 injuries, and 15.4% reporting more than 3 career injuries. Injuries were most commonly encountered during corporal dilation (71.1%) compared with corporal exposure (12.5%) or penile straightening maneuvers (7.0%). There was no statistically significant difference with aborting or continuing implantation among GURS-trained, SMSNA-trained, other fellowship-trained, and non-fellowship-trained surgeons. Of all responders, 55% would abort the procedure after distal urethral injury, whereas 45% would continue the procedure with unilateral or bilateral insertion of cylinders. Patient factors that increased likelihood of terminating the procedure in the case of urethral injury included immunosuppression, spinal cord injury, and clean intermittent catheterization dependence. CLINICAL IMPLICATIONS: A urethral injury during penile prosthesis implantation might not mandate termination of the procedure despite classic teaching. STRENGTHS AND LIMITATIONS: The strength of this study is that it provides difficult to obtain epidemiologic data on the frequency and management of this clinically significant injury. Limitations include the inherent biases from a survey-based study including response bias and recall bias. The survey response rate could not be obtained. CONCLUSION: Urethral injury during penile prosthesis implantation is a rare but clinically significant risk of the procedure, with many variations in management of the injury. Termination and delayed implantation might not be necessary after injury, although long-term outcome data are difficult to obtain. Sexton SJ, Granieri MA, Lentz AC.

Reconstructive Management Pearls for the Transgender Patient.

PURPOSE OF REVIEW: A growing number of transgender patients are seeking gender-affirming genital reconstructive surgery (GRS). These complex procedures have high complication rates. We describe common surgical pitfalls in GRS and approaches for minimizing complications. RECENT FINDINGS: Penile inversion vaginoplasty has been associated with excellent cosmetic and functional outcomes. A robotic-assisted dissection may minimize risk of rectal injury. As a younger transgender population chooses pubertal suppression, alternative sources for lining the vaginal canal, such as enteric vaginoplasties, may be more widely utilized. Since adoption of microvascular techniques in phalloplasty, transmasculine individuals have potential for a sensate neophallus and penetrative intercourse. Urethral complications are common and challenging to manage; techniques using flap coverage may minimize ischemia-related strictures. Innovations in prosthesis placement require adaptations to neophallus anatomy. A growing number of transgender individuals are seeking genital reconstruction. Ongoing innovation in surgical technique is needed to improve patient outcomes.

The evolution of urethroplasty for bulbar urethral stricture disease: lessons learned from a single center experience.

PURPOSE: We reviewed the evolution of repairs for bulbar urethral stricture disease and analyzed changes in outcomes. MATERIALS AND METHODS: We retrospectively reviewed the records of 429 men who underwent urethroplasty for bulbar urethral stricture disease from January 1996 to September 2011. Patient demographics, stricture related details, and intraoperative and postoperative information were collected. We used 1-way ANOVA for differences in age and stricture length, the Fisher exact test for differences in recurrence rates, and the t-test and chi-square test with the Bonferroni correction for subgroup analysis. RESULTS: Of the 429 men 384 (90%) had followup data available. Buccal mucosa surpassed penile skin as our preferred tissue for augmented anastomotic repairs by 1999. It was accompanied by an improved recurrence rate (21.6% vs 5.8%, p = 0.002). The average length of strictures treated with excision and primary anastomosis increased after 2004 (1.29 vs 1.54 cm, p = 0.05) but this was not associated with a significant change in the recurrence rate (3.0% vs 6.9%, p = 0.27). CONCLUSIONS: The transition from penile skin to buccal mucosa for augmented anastomotic repair was relatively abrupt. We have become more aggressive when performing excision and primary anastomosis with respect to stricture length. These changes resulted in improved outcomes. Continuing review of our practices, awareness of results reported by others and intuition contributed to our changes but prospective analysis will be the best way to continually improve outcomes.

Lichen sclerosus in men is associated with elevated body mass index, diabetes mellitus, coronary artery disease and smoking.

PURPOSE: To elucidate disease associations and possible etiology of lichen sclerosus (LS), we identified comorbidities present in men with LS. LS is a chronic inflammatory disease of unknown etiology affecting genitals and urethra of men commonly resulting in strictures. METHODS: Men with LS of the urethra, penis, prepuce and scrotum were identified. A control population was generated from men seen in the Department of Urology matched by age and race in a 5:1 ratio. A case-control study was performed and comorbidities identified by ICD9, CPT codes and medication use via systematic electronic medical record review. Subgroup analysis of men with urethral strictures was performed based on their LS status. RESULTS: Men with LS had a significantly higher mean body mass index [31.0 (range 18.9-52.6)] compared to controls [28.1 (16.8-64.1), p = 0.001], significantly increased rate of coronary artery disease (CAD) (15.3 vs. 8.9%, p = 0.05) as well as a twofold higher rate of diabetes mellitus (15.5 vs. 8.3%, p = 0.02). Of men with LS and stricture disease, 11/19 (58%) were current or former smokers, compared to 28% of men with strictures without LS (p = 0.006). No association of LS with other morbidities like hyperlipidemia, hypertension, cerebrovascular disease, peripheral vascular disease or dermatologic disorders was found. CONCLUSIONS: Men suffering from LS have an increased BMI and a higher prevalence of concomitant CAD, diabetes mellitus and tobacco use. Development and chronicity of LS may not be a purely dermatologic condition, but be associated or confounded by systemic or vascular compromise from disorders of CAD, DM and smoking.

Presenting symptoms of anterior urethral stricture disease: a disease specific, patient reported questionnaire to measure outcomes.

PURPOSE: We evaluated the spectrum of symptoms in men with urethral stricture presenting for urethroplasty. MATERIALS AND METHODS: We identified 214 men who underwent anterior urethroplasty by a single surgeon (CMG) from March 2001 to June 2010. We retrospectively reviewed the initial patient history. All voiding and sexual dysfunction symptoms were recorded. RESULTS: The most common presenting voiding complaints were weak stream in 49% of cases and incomplete emptying in 27%. Overall 21% of men did not present with voiding symptoms specifically addressed by the American Urological Association symptom index. The most common of these symptoms were spraying of urinary stream in 13% of men and dysuria in 10%. No symptoms were reported in 10% of men. Men with lichen sclerosus were more likely to present with obstructive symptoms (76% vs 55%) while men with penile urethral stricture were more likely to present with urinary stream spraying (17% vs 6%, each p <0.05). Sexual dysfunction was reported by 11% of men, most commonly in those with failed hypospadias repair (23% vs 9%) and lichen sclerosus (24% vs 10%, each p <0.05). CONCLUSIONS: While the American Urological Association symptom index captures the most common voiding complaints of men with urethral stricture, 21% of those who presented for urethroplasty did not have voiding symptoms assessed by the index. A validated, disease specific instrument is needed to fully capture the presenting voiding symptoms and sexual dysfunction complaints of men with urethral stricture disease.

Distal urethroplasty for isolated fossa navicularis and meatal strictures.

OBJECTIVE: • Urethral strictures located in the fossa navicularis are common and are often managed with meatotomy or meatoplasty. • Few data have described the outcomes for men after urethroplasty or patient satisfaction following these procedures. METHODS: • In all, 93 men at two different institutions underwent surgical repair of distal urethral stricture disease using meatotomy (73) or meatoplasty (20), with 13/20 (65%) of the latter group undergoing substitution urethroplasty. • In patients with lichen sclerosus (LS), all involved tissue was excised prior to reconstruction. • In a subset of men undergoing meatotomy, patient satisfaction was evaluated by questionnaire. RESULTS: • Average clinical follow-up for men undergoing distal urethroplasty was 61 months. • Successful reconstruction requiring no further intervention occurred in 84% of men overall. Subgroup analysis revealed success in 87% of men with meatotomy, 75% with meatoplasty and 66% with substitution urethroplasty. • Men with LS had a significantly greater rate of stricture recurrence (20.5% vs 7.5%, P= 0.04). • Of the subset of men who completed a patient-based questionnaire 84% reported they were either satisfied or very satisfied with the results of their meatotomy. CONCLUSIONS: • We report the success of distal urethral stricture management. • Meatal strictures may be approached successfully in a stepwise manner progressing from meatotomy to meatoplasty for longer recurrent strictures, with a high overall success rate for meatotomy. • Although substitution grafts may be useful for men with longer distal strictures and those with LS, the risk of recurrence was significantly higher in this cohort.

Urethroplasty for radiotherapy induced bulbomembranous strictures: a multi-institutional experience.

PURPOSE: Radiotherapy induced urethral strictures are often difficult to manage due to proximal location, compromised vascular supply and poor wound healing. To determine the success of urethroplasty for radiation induced strictures we performed a multi-institutional review of men who underwent urethroplasty for urethral obstruction. MATERIALS AND METHODS: A total of 30 men (mean age 67 years) underwent urethroplasty at 3 separate institutions. Excision with primary anastomosis was used in 24 of 30 patients (80%), with 4 of 30 requiring a genital fasciocutaneous skin flap and 2 a buccal graft. Hospitalization was less than 23 hours for 70% of the patients. Recurrence was defined as cystoscopic identification of urethral narrowing to less than 16Fr in diameter. RESULTS: All strictures were located in the bulbomembranous region. Mean stricture length was 2.9 cm (range 1.5 to 7). External beam radiotherapy for prostate cancer was the etiology of stricture disease in 15 men (50%), with brachytherapy in 7 (24%) and a combination of the 2 modalities in 8 (26%). Successful urethral reconstruction was achieved in 22 men (73%) at a mean of 21 months. Mean time to stricture recurrence was 5.1 months (range 2 to 8). Two men required balloon dilation after stricture recurrence and none required urinary diversion. Incontinence was transient in 10% and persistent in 40%, with 13% requiring an artificial urinary sphincter. The rate of erectile dysfunction was unchanged following urethroplasty (47% preoperative, 50% postoperative). CONCLUSIONS: Urethroplasty for radiation induced strictures has an acceptable rate of success and can be performed without tissue transfer techniques in most cases. Almost half of men will experience some degree of incontinence as a result of surgery but erectile function appears to be preserved.

Prospective analysis of ejaculatory function after anterior urethral reconstruction.

PURPOSE: Urethral reconstruction may improve ejaculatory function by relieving urethral obstruction but could worsen it by disrupting the bulbocavernosus muscle. We prospectively evaluated the effects of urethral reconstruction on ejaculatory function. MATERIALS AND METHODS: All men who underwent anterior urethroplasty from September 2006 to June 2009 were asked to complete the ejaculatory function component of the Male Sexual Health Questionnaire (7 questions with a total of 35 points) preoperatively and postoperatively after resuming sexual activity. Postoperatively decreased and improved ejaculation was defined as an increase and a decrease of 5 or more points, respectively. RESULTS: A total of 43 men were included in the study. The overall ejaculatory score did not change postoperatively (25.54 vs 26.94 points, p = 0.17) at a mean +/- SD followup of 8.1 +/- 6.0 months but men with poor preoperative function had significant improvement (15.27 vs 21.22 points, p = 0.01). Overall ejaculatory vigor (3.19 vs 3.56 points, p = 0.25) and volume (3.49 vs 3.88, p = 0.19) did not change significantly. Postoperative function was stable in 30 men (70%), improved in 8 (19%), including 7 with bulbar and 1 with penile urethroplasty, and worse in 5 (11%), including 4 with bulbar and 1 with penile urethroplasty. CONCLUSIONS: Urethral reconstruction appears to have a minimal effect on ejaculatory function when evaluated by the Male Sexual Health Questionnaire. More objective testing may be necessary to fully assess the effect of urethroplasty on ejaculatory function.

Prospective analysis of erectile dysfunction after anterior urethroplasty: incidence and recovery of function.

PURPOSE: Anterior urethroplasty has been shown to negatively impact erectile function. Recovery of function is common but the likelihood and extent of recovery have not been fully elucidated. MATERIALS AND METHODS: Between October 2006 and May 2008 men undergoing anterior urethroplasty were enrolled in a prospective study to evaluate the effects of urethroplasty on erectile function. The International Index of Erectile Function was completed preoperatively and on all subsequent postoperative visits. Preoperative and postoperative erectile function was compared. RESULTS: A total of 52 patients who underwent anterior urethroplasty were included in the study. Repair locations were bulbar (35) and penile (17). Of the patients undergoing bulbar urethroplasty 20 had excision and primary anastomosis, and 15 had augmented anastomotic repair. All penile repairs were ventral onlay repair (11) or inlay repair in 2 stages (6). Postoperative erectile dysfunction was noted in 20 (38%) men, of whom 18 recovered fully at a mean postoperative period of 190 days (range 92 to 398). In patients with normal preoperative erectile function bulbar urethroplasty was more likely than penile urethroplasty to cause erectile dysfunction (76% vs 38%, p = 0.05). Within the bulbar urethra excision and primary anastomosis repairs led to slightly higher erectile dysfunction rates than augmented anastomotic repairs (50% vs 26%, p = 0.16). CONCLUSIONS: Anterior urethroplasty caused erectile dysfunction in approximately 40% of patients, although recovery was seen in most by 6 months. Bulbar urethroplasty appears to affect erectile function to a greater extent than penile urethroplasty, which may be explained by the proximity of the bulbar urethra to the nerves responsible for erection.

Stricture recurrence after urethroplasty: a systematic review.

PURPOSE: Urethroplasty remains the gold standard for the management of urethral stricture disease with acceptable long-term success. However, the standard by which stricture recurrence is defined and evaluated after urethral reconstruction remains widely variable. We conducted a systematic review of the urological literature to determine how stricture recurrence is defined and evaluated. MATERIALS AND METHODS: A systematic review was conducted on all contemporary urethroplasty articles published between 2000 and 2008. Using the term "urethroplasty" 302 articles were identified and evaluated. A total of 86 articles were included in the analysis. RESULTS: The overall recurrence rate for all reconstructive procedures was 15.6%, which remained stable between 2000 and 2008. Stricture recurrence was determined by a mean of 3 (range 1 to 8) different diagnostic tests. The most common primary diagnostic tests for recurrence were uroflowmetry (56% of articles) and retrograde urethrography (51%). Cystourethroscopy was used as a primary screen to identify stricture recurrence in 25% of articles, and as a secondary procedure in another 21%. Recurrence was defined as the need for an additional surgical procedure or dilation in 75% and 52% of articles, respectively. CONCLUSIONS: The methods used to determine stricture recurrence after urethroplasty remain widely variable. The use of a standardized surveillance protocol to define stricture recurrence after urethral reconstruction may allow more effective comparison of urethroplasty outcomes across institutions.

Presenting Complications to a Reconstructive Urologist After Masculinizing Genital Reconstructive Surgery.

OBJECTIVE: To evaluate the presenting complications of patients to reconstructive urologists after masculinizing gender affirming genital reconstructive surgery (GRS) performed elsewhere. METHODS: We identified patients who underwent revision surgery by one of the co-authors for sequelae of masculinizing GRS. We reviewed patient demographics, medical history, details of prior GRS, and complications from GRS. Specific attention was paid to the presence of the following: suprapubic tube dependence, vaginal remnant, urethrocutaneous fistula (UCF) within the fixed urethra (pars fixa), UCF in the phallic urethra, phallic urethral stricture, meatal stenosis, and anastomotic urethral stricture. Statistical analysis was performed using the Fisher's exact test to determine differences in presenting symptoms by GRS. RESULTS: Fifty-five patients who had reconstructive surgery for complications from masculinizing GRS from September 2004 to September 2017 were identified. The median age at surgical correction was 33 years. Fifteen (27%) patients had prior metoidioplasty and 40 (73%) had prior phalloplasty. The median time from date of GRS to presentation to a reconstructive urologist was 4 months. Urethral strictures (n = 47, 86%) were the most common indication for subsequent surgery, followed by urethrocutaneous fistulae (n = 31, 56%) and vaginal remnant (n = 26, 47%). The majority of patients presented with 2 or more simultaneous complications (n = 40, 73%). CONCLUSION: There are several common presenting urologic complications after masculinizing GRS. Patients may present to reconstructive urologists early after GRS performed elsewhere. The long-term outcomes of GRS deserve further study.

Robotics and urologic reconstructive surgery.

Minimally invasive surgery has made a profound impact on how urologists approach the challenges in reconstruction of the urinary tract. The advent of laparoscopic approaches to reconstructive urology have demonstrated comparable outcomes to open surgery with improved morbidity. The recent adoption of robotic surgery has seen further advancements such as improved visibility and, freedom of movement, and an easier technical learning curve. With these advantages, more reconstructive urology procedures are being performed robotically. Herein, we review reconstructive urology procedures for which robotics have been applied.

Robotic Y-V Plasty for Recalcitrant Bladder Neck Contracture.

OBJECTIVE: To demonstrate the technique and the outcomes of robot assisted Y-V plasty bladder neck reconstruction (RYVBNR). METHODS: We present our technique for treatment of recalcitrant bladder neck contracture (BNC) in 7 patients who underwent RYVBNR at our institution between March 2016 and September 2017. Indication for the procedure was incomplete emptying, recurrent urinary tract infections, and dysuria. On follow-up, patients were assessed for clinical success by absence of infections, symptoms, and cystoscopic evaluation. Robotic assisted dissection is performed to open the space of Retzius and mobilize the bladder. The cystoscope is passed to the level of the BNC, and Firefly technology is used to localize the BNC. The BNC is incised anteriorly, and a V-shaped bladder flap is advanced into the BNC in a Y-V plasty fashion. We place a perioperative closed suction drain, which is removed before discharge, and a 22 Fr catheter, which that will be removed in the office at approximately 2 weeks. RESULTS: Six men developed recalcitrant BNCs and 1 developed a recalcitrant vesicourethral anastomotic stenosis. All patients had previously undergone an endoscopic procedure. Median time for last attempt at endoscopic management to robot-assisted bladder neck repair was 4.7 months. The average number of prior attempts at endoscopic management was 2. All patients underwent RYVBNR without conversion to open surgery. The median operative time was 240 minutes, estimated blood loss was 67 mL, and length of stay was 1 day. There were no intraoperative complications. Catheters were removed in the office at a median time of 15 days. At a median follow-up of 8 months, all cases were successful with no evidence of recurrence. Only 2 patients had persistent urinary incontinence at 1 pad per day. CONCLUSION: RYVBNR with a Y-V plasty is a feasible and effective technique for managing a difficult reconstructive problem.

Patency and Incontinence Rates After Robotic Bladder Neck Reconstruction for Vesicourethral Anastomotic Stenosis and Recalcitrant Bladder Neck Contractures: The Trauma and Urologic Reconstructive Network of Surgeons Experience.

OBJECTIVE: To review a robotic approach to recalcitrant bladder neck obstruction and to assess success and incontinence rates. MATERIALS AND METHODS: Patients with a recalcitrant bladder neck contracture or vesicourethral anastomotic stenosis who underwent robotic bladder neck reconstruction (RBNR) were identified. We reviewed patient demographics, medical history, etiology, previous endoscopic management, cystoscopic and symptomatic outcomes, urinary continence, and complications. Stricture success was anatomic and functional based upon atraumatic passage of a 17 Fr flexible cystoscope or uroflowmetry rate >15 ml/s. Incontinence was defined as the use of >1 pad per day or procedures for incontinence. RESULTS: Between 2015 and 2017, 12 patients were identified who met study criteria and underwent RBNR. Etiology of obstruction was endoscopic prostate procedure in 7 and radical prostatectomy in 5. The mean operative time was 216 minutes (range 120-390 minutes), with a mean estimated blood loss of 85 cc (range 5-200 cc). Median length of stay was 1 day (range 1-5 days). Three of 12 patients had recurrence of obstruction for a 75% success rate. Additionally, 82% of patients without preoperative incontinence were continent with a median follow-up of 13.5 months (range 5-30 months). There was 1 Clavien IIIb complication of osteitis pubis and pubovesical fistula that required vesicopubic fistula repair with pubic bone debridement. CONCLUSION: RBNR is a viable surgical option with high patency rates and favorable continence outcomes. This is in contrast to perineal reconstruction, which has high incontinence rates. If future incontinence procedures are needed, outcomes may be improved given lack of previous perineal dissection.
