One or Two Stage Buccal Augmented Urethroplasty has a High Success Rate in Treating Post Phalloplasty Anastomotic Urethral Stricture.

OBJECTIVE: To describe the outcomes of single-stage and staged repairs in properly selected patients with phalloplasty anastomotic strictures. METHODS: A bi-institutional retrospective review was performed of all patients who underwent anastomotic stricture repairs between 7/2014-8/2020. Those who had prior augmented urethroplasties or poorly vascularized tissue underwent two-stage repairs (Group-2), all others underwent single-stage repair with a double-face (dorsal inlay and ventral onlay) buccal mucosal graft urethroplasty (Group-1). Postoperatively, urethral patency and patient reported outcome measures (PROMs) were assessed. RESULTS: Twenty-three patients with anastomotic strictures were identified. Fourteen patients met inclusion criteria and had 1-year follow-up (9 in Group-1; 5 in Group-2). Nine patients (64%) had prior failed interventions (56% Group-1; 80% Group-2). At a mean follow-up of 33.9 (Group-1) and 35.2 months (Group-2) there were two stricture recurrences in Group-1 (22%) and none in Group-2. PROMs were completed by 12 patients. All patients reported the ability to void standing. Post-void dribbling was present in the majority of patients (7/7 Group-1; 2/4 in Group-2). Mean IPSS was 3.9 (0-14) for Group-1 and 1 (0-3) for Group-2. All reported at least a moderate improvement in their condition on GRA (Group-1 +3 71%, +2 29%; Group-2 +3 100%). CONCLUSION: Single-stage repairs are feasible for patients with anastomotic strictures who have well vascularized tissue and no prior single-stage buccal mucosa augmented urethroplasty failures. Staged repairs are feasible for patients with poor tissue quality. Proper patient selection is important for successful reconstruction.

Robotic-assisted Vaginectomy During Staged Gender-affirming Penile Reconstruction Surgery: Technique and Outcomes.

OBJECTIVE: To report our novel technique and mid-term follow-up for robotic-assisted laparoscopic vaginectomy (RALV), a component procedure of staged gender-affirming penile reconstructive surgery. MATERIALS AND METHODS: The records of patients seeking gender-affirming penile reconstructive surgery who underwent RALV, performed by a single surgeon at our institution, between May 2016 and January 2020 were reviewed retrospectively for demographic and perioperative data. Patients were included irrespective of history of previous phalloplasty. A subset of these patients elected to have urethral lengthening during second stage phalloplasty for which an anterior vaginal mucosa flap urethroplasty was performed. Postoperative complications and outcomes and most recent follow-up were obtained. RESULTS: A total of 42 patients were reviewed, of whom 19 (45%) patients ultimately had radial forearm free flap, 15 (41%) had anterolateral thigh flap, 5 (12%) had metoidioplasty, and 1 (2.4%) had abdominal phalloplasty. A vaginal mucosa and gracilis flap was used in all of 36 (86%) patients in whom a pars fixa was created. Average operative time was 299 minutes (range 153-506). Median estimated blood loss was 200 mL (range 100-400). Median length of stay was 3 days (range 1-7). Complications within 30 days from surgery occurred in 15 patients (36%), of whom 12/15 were Clavien-Dindo grade 1 or 2, and 11/15 had complications unrelated to vaginectomy. Of the 4 patients who had vaginectomy-related complications, all resolved with conservative management. Median overall follow-up was 15.8 months. CONCLUSION: RALV offers a safe and efficient approach during staged gender-affirming penile reconstruction and may mitigate the subsequent risk of urethral complications.

Outcomes of Gender Affirming Peritoneal Flap Vaginoplasty Using the Da Vinci Single Port Versus Xi Robotic Systems.

BACKGROUND: Robotic-assisted peritoneal flap gender-affirming vaginoplasty (RPGAV) with the da Vinci Xi system has been reported to be a safe alternative to traditional penile inversion vaginoplasty. Utilizing the Single Port (SP) robot system, our surgical approach has evolved. OBJECTIVE: To describe a step-by-step technique for RPGAV using the SP robot and to compare outcomes between Xi and SP systems. DESIGN, SETTING, AND PARTICIPANTS: A total of 145 transgender women underwent RPGAV between September 2017 and December 2019. We retrospectively reviewed data for patients with a minimum 6 mo of follow-up. SURGICAL PROCEDURE: Peritoneal flaps are harvested from the posterior bladder and pararectal fossa. The vaginal space is dissected transabdominally. Inverted penile flap with or without scrotal graft is sutured to the peritoneal flaps, which form the neovaginal apex. MEASUREMENTS: Demographics, perioperative data, and clinical outcomes were evaluated. RESULTS AND LIMITATIONS: A total of 100 (Xi = 47; SP = 53) patients had a minimum 6 mo of follow-up. The mean age was 36.2 (range 16.1-71.4) yr. Average procedure times were 4.2 and 3.7 h in Xi and SP cohorts, respectively (p <0.001). At the mean follow-up of 11.9 (range 6.0-25.4) mo, vaginal depth and width were 13.6 (range 9.7-14.5) and 3.7 (range 2.9-3.8) cm in the Xi group, and 14.1 (range 9.7-14.5) and 3.7 (range 3.5-3.8) cm in the SP group (p =0.07 and 0.04, respectively). Complications included transfusion (6%), rectovaginal fistula (1%), bowel obstruction (2%), pelvic abscess (1%), and vaginal stenosis (7%). CONCLUSIONS: RPGAV using the SP robot reduces operative time by facilitating a dual-surgeon abdominal-perineal approach. There is no difference in complication rates between the two approaches. PATIENT SUMMARY: We studied the outcomes of robotic peritoneal flap vaginoplasty with two robot systems. With both systems, patients had good vaginal depth and width at an average follow-up of 1 yr. Surgery time was shorter with the Single Port (SP) robot.

Robotic Ureteral Reconstruction.

Robotically assisted laparoscopic techniques may be used for proximal and distal ureteral strictures. Distal strictures may be approached with ureteroneocystotomy, psoas hitch, and Boari flap. Ureteroureterostomy, buccal mucosa graft ureteroplasty, and appendiceal flap ureteroplasty are viable techniques for strictures anywhere along the ureter. Ileal ureteral substitution is reserved for more extensive disease, and autotransplantation is reserved for salvage situations.

A Multi-Institutional Experience With Robotic Appendiceal Ureteroplasty.

OBJECTIVE: To report a multi-institutional experience with robotic appendiceal ureteroplasty. METHODS: This is a retrospective review of 13 patients undergoing right appendiceal flap ureteroplasty at 2 institutions between April 2016 and October 2019. The primary endpoint was surgical success defined by the absence of flank pain and radiographic evidence of ureteral patency. RESULTS: Eight of 13 (62%) underwent appendiceal onlay while 5/13 (38%) underwent appendiceal interposition. Mean length of stricture was 6.5 cm (range 1.5-15 cm) affecting anywhere along the right ureter. Mean operative time was 337 minutes (range 206-583), mean estimated blood loss was 116 mL (range 50-600), and median length of stay was 2.5 days (range 1-9). Balloon dilation was required in 1/12 (8%). One patient died on postoperative day 0 due to a sudden cardiovascular event. Otherwise, there were no complications (Clavien-Dindo > 2) within 30 days from surgery. At a mean follow up of 14.6 months, 11/12 (92%) were successful. CONCLUSION: Robotic appendiceal ureteroplasty for right ureteral strictures is a versatile technique with high success rates across institutions.

Multi-institutional Experience Comparing Outcomes of Adult Patients Undergoing Secondary Versus Primary Robotic Pyeloplasty.

OBJECTIVE: To describe surgical techniques and peri-operative outcomes with secondary robotic pyeloplasty (RP), and compare them to those of primary RP. METHODS: We retrospectively reviewed our multi-institutional, collaborative of reconstructive robotic ureteral surgery (CORRUS) database for all consecutive patients who underwent RP between April 2012 and September 2019. Patients were grouped according to whether they underwent a primary or secondary pyeloplasty (performed for a recurrent stricture after previously failed pyeloplasty). Perioperative outcomes and surgical techniques were compared using nonparametric independent sample median tests and chi-square tests; P < .05 was considered significant. RESULTS: Of 158 patients, 28 (17.7%) and 130 (82.3%) underwent secondary and primary RP, respectively. Secondary RP, compared to primary RP, was associated with a higher median estimated blood loss (100.0 vs 50.0 milliliters, respectively; P < .01) and longer operative time (188.0 vs 136.0 minutes, respectively; P = .02). There was no difference in major (Clavien >2) complications (P = .29). At a median follow-up of 21.1 (IQR: 11.8-34.7) months, there was no difference in success between secondary and primary RP groups (85.7% vs 92.3%, respectively; P = .44). Buccal mucosa graft onlay ureteroplasty was performed more commonly (35.7% vs 0.0%, respectively, P < .01) and near-infrared fluorescence imaging with indocyanine green was utilized more frequently (67.9% vs 40.8%, respectively; P < .01) for secondary vs primary repair. CONCLUSION: Although performing secondary RP is technically challenging, it is a safe and effective method for recurrent ureteropelvic junction obstruction after a previously failed pyeloplasty. Buccal mucosa graft onlay ureteroplasty and utilization of near-infrared fluorescence with indocyanine green may be particularly useful in the re-operative setting.

Urethral stricture after phalloplasty.

Phalloplasty is a critical step for many transgender men who seek relief from gender dysphoria; however, phalloplasty is a difficult and complex surgery with many potential complications. The most common complications are urinary, mostly comprised of urethrocutaneous (UC) fistulas and urethral strictures. Improvements in surgical technique have driven down complication rates over the past few decades. Despite these innovations, complication rates remain high, and transgender surgeons must be well versed in their diagnosis and treatment. Over the same time period, gender affirming surgery has seen unprecedented growth in the United States. Transgender surgeons are few, and their patients often travel great distances for their index surgery. As such, locally available reconstructive urologists will be called upon to treat these complications with greater frequency and must be proficient in diagnosis and treatment to help these patients achieve a good outcome.

Total Phalloplasty With Latissimus Dorsi Musculocutaneous Flap in Female-to-male Transgender Surgery.

OBJECTIVE: To present our technique of musculocutaneous latissimus dorsi (MLD) free-flap total phalloplasty. This technically demanding female-to-male gender reassignment surgery consists of creating a neophallus from extragenital tissue. METHODS: The presented technique included: removal of internal and/or external female genitalia, creation of neophallus using latissimus dorsi free flap, clitoral incorporation into the neophallus, urethral lengthening, and insertion of testicular implants into the newly created scrotum. The MLD flap with proper dimension is harvested from nondominant side and tubularized. Microvascular anastomosis is done between thoracodorsal vessels and femoral artery and saphenous vein. Neophallus is positioned in adequate place. Urethroplasty is performed by combining different genital flaps that are harvested from anterior vaginal wall, urethral plate, and both labia minora and clitoral skin. Scrotoplasty is done by joining both labia majora with implantation of testicular implants. RESULTS: Operative time was 427 minutes with minimal blood loss. Both donor site and graft healed well, and the patient reports voiding well while standing. Penile prosthesis implantation as well as neophallic urethroplasty are planned for the second stage. CONCLUSION: Total MLD flap phalloplasty with urethral lengthening is a challenging and complex surgical procedure. This technique presents good variant for female transgenders with acceptable cosmetic outcome and enables good volume of neophallus, sexual arousal, and voiding while standing.
