Genital Hypoplasia before Gender-Affirming Vaginoplasty: Does the Robotic Peritoneal Flap Method Create Equivalent Vaginal Canal Outcomes?

BACKGROUND: Insufficient genital tissue has been reported as a barrier to achieving depth in gender-affirming vaginoplasty. The authors sought to characterize vaginal depth and revision outcomes in patients with genital hypoplasia undergoing robotic peritoneal flap vaginoplasty. METHODS: Retrospective case-control analysis of patients undergoing robotic peritoneal vaginoplasty between September of 2017 and August of 2020 was used. All 43 patients identified as having genital hypoplasia (genital length <7 cm) were included with 49 random controls from the remaining patients with greater than 7 cm genital length. Baseline clinical characteristics and perioperative variables were recorded to identify potential confounders. Outcomes measured included vaginal size reported at last visit and undergoing revision surgery for depth or for vulvar appearance. RESULTS: Patients were well matched other than median body mass index at the time of surgery, which was greater in the hypoplasia cohort by 3.6 kg/m 2 ( P < 0.0001). Patients had a median of 1-year of follow-up, with a minimum follow-up of 90 days. No significant differences in outcomes were observed, with a median vaginal depth of 14.5 cm (interquartile range, 13.3 to 14.5 cm), and a median width of dilator used of 3.8 cm (interquartile range, 3.8 to 3.8 cm). No depth revisions were observed, and an 11% ( n = 10) rate of external revision occurred. CONCLUSIONS: Patients with genital hypoplasia had equivalent dilation outcomes in a case-control analysis with consistent follow-up past 90 days. The robotic peritoneal flap vaginoplasty technique provides vaginal depth of 14 cm or greater regardless of genital tissue before surgery. Further investigation with patient-reported outcome measures is warranted. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Does Genital Self-image Correspond with Sexual Health before and after Vaginoplasty?

Patient-reported outcomes regarding sexual health are lacking or have not been validated for transgender patients following vaginoplasty. The aim of this study is to further characterize the difference in sexual health, genital self-image, and the relationship between them for patients who were pre- and postvaginoplasty. Methods: A community advisory board informed an anonymous online survey utilizing patient-reported outcomes. Pre- and postvaginoplasty respondents were recruited online. Survey measures included the Female Genital Self-Image Scale (FGSIS) and the Patient-Reported Outcomes Measurement Information System sexual health measures. Welch approximation t tests were performed for FGSIS and Patient-Reported Outcomes Measurement Information System questions, using Bonferroni correction. Results: A total of 690 respondents prevaginoplasty (n = 525; 76%) and postvaginoplasty (n = 165; 24%) participated. The postoperative cohort, compared with the preoperative cohort, reported higher scores for orgasm (P = 0.0003), satisfaction (P = 0.001), and pleasure (P = 0.002). FGSIS total score was higher among postoperative respondents (79.4% ± 17.1%) than preoperative respondents (50.6% ± 15.1%) (P < 0.0001). Using Spearman rho, no significant correlation between FGSIS total score and any Patient-Reported Outcomes Measurement Information System subsectional measures was observed for the postoperative cohort, but a correlation (P <0.001) was observed for the preoperative cohort. Conclusions: Individuals who are contemplating vaginoplasty have worse sexual health and genital self-image than those who underwent vaginoplasty, yet genital self-image does not correlate directly with sexual health. Sexual health is multimodal for each person.

Perioperative Hormone Management in Gender-Affirming Mastectomy: Is Stopping Testosterone before Top Surgery Really Necessary?

BACKGROUND: Gender-affirming mastectomy, or "top surgery," has become one of the most frequently performed procedures for transgender and nonbinary patients. However, management of perioperative testosterone therapy remains controversial. Despite a lack of supporting evidence, many surgeons require cessation of testosterone before top surgery. This is the first study to compare complication rates in patients undergoing gender-affirming mastectomy with and without discontinuation of perioperative testosterone. METHODS: This retrospective review included patients undergoing top surgery by the senior author between 2017 and 2020. Reflecting a change in the senior author's practice, before May of 2019, all patients were required to discontinue testosterone before surgery; all patients treated after this point continued their testosterone regimens throughout the perioperative period. Patients were stratified according to testosterone regimen and perioperative hormone management, with demographic characteristics and postoperative outcomes compared among groups. RESULTS: A total of 490 patients undergoing gender-affirming mastectomy during the study period were included. Testosterone was held perioperatively in 175 patients and continued in 211 patients; 104 patients never received testosterone therapy. Demographic characteristics were similar among groups and there was no difference in rates of hematoma (2.9% versus 2.8% versus 2.9%, respectively; P = 0.99), seroma (1.1% versus 0% versus 1%, respectively; P = 0.31), venous thromboembolism (0% versus 0.5% versus 0%, respectively; P = 0.99), or overall complications (6.9% versus 4.3% versus 5.8%, respectively; P = 0.54). CONCLUSIONS: Our results demonstrate no difference in postoperative complication rates among groups. Whereas further investigation is warranted, our data suggest that routine cessation of testosterone in the perioperative period is not necessary for patients undergoing gender-affirming mastectomy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Durable Treatment of Refractory Vesicourethral Anastomotic Stenosis via Robotic-assisted Reconstruction: A Trauma and Urologic Reconstructive Network of Surgeons Study.

BACKGROUND: Refractory vesicourethral anastomotic stenosis (VUAS) after radical prostatectomy poses challenges distinct from bladder neck contracture, due to close proximity to the sphincter mechanism. Open reconstruction is technically demanding, risking de novo stress urinary incontinence (SUI) or recurrence. OBJECTIVE: To demonstrate patency and continence outcomes of robotic-assisted VUAS repair. DESIGN, SETTING AND PARTICIPANTS: Patients with VUAS underwent robotic-assisted reconstruction from 2015 to 2020 in the Trauma and Urologic Reconstructive Network of Surgeons (TURNS) consortium of institutions. The minimum postoperative follow-up was 3 mo. SURGICAL PROCEDURE: The space of Retzius is dissected and fibrotic tissue at the vesicourethral anastomosis is excised. Reconstruction is performed with either a primary anastomotic or an anterior bladder flap-based technique. MEASUREMENTS: Patency was defined as either the passage of a 17 French flexible cystoscope or a peak flow on uroflowmetry of >15 ml/s. De novo SUI was defined as either more than one pad per day or need for operative intervention. RESULTS AND LIMITATIONS: A total of 32 patients met the criteria, of whom 16 (50%) had a history of pelvic radiation. Intraoperatively, 15 (47%) patients had obliterative VUAS. The median length of hospital stay was 1 d. At a median follow-up of 12 mo, 24 (75%) patients had patent repairs and 26 (81%) were voiding per urethra. Of five men with 30-d complications, four were resolved conservatively (catheter obstruction and ileus). In eight patients, recurrent stenoses were managed with redo robotic reconstruction (in two), endoscopically (in four), or catheterization (in two). Of 13 patients without preexisting SUI, 11 (85%) remained continent at last follow-up. No patients underwent urinary diversion. CONCLUSIONS: Robotic-assisted VUAS reconstruction is a viable and successful management option for refractory anastomotic stenosis following radical prostatectomy. The robotic transabdominal approach demonstrates high patency and continence rates. PATIENT SUMMARY: We studied the outcomes of robotic-assisted repair for vesicourethral anastomotic stenosis. Most patients, after the procedure, were able to void per urethra and preserve existing continence.

Single-Port Robotic Posterior Urethroplasty Using Buccal Mucosa Grafts: Technique and Outcomes.

OBJECTIVE: To describe the technique, feasibility and short-term outcomes of buccal mucosa grafts in robotic lower urinary tract reconstruction. METHODS: We reviewed 9 patients who underwent single-port robotic posterior urethroplasty with buccal mucosa graft from May-December 2019. Variables included patient demographics, diagnosis/etiology, and intraoperative parameters. Intraabdominal or extraperitoneal transvesical approaches are used for the stricture via supraumbilical access, and if necessary, perineal dissection is performed. Cystoscopy identifies the extent of stenosis. Anastomosis is completed with buccal mucosal graft and rectus abdominis, omental or gracilis flaps as needed. RESULTS: The mean age was 65.4 years. Robotic urethroplasty with buccal mucosa graft was performed for vesicourethral anastomotic strictures (n = 7), urethral strictures (n = 4), pubic fistula after robotic posterior urethroplasty (n = 1), and anastomotic distraction (n = 1). Strictures occurred after prostate cancer treatments (n = 8) and trauma (n = 1). All patients had prior failed endoscopic interventions: balloon dilatation, resection/incision of bladder neck, internal urethrotomy under direct vision, urethral stents, and posterior urethroplasty. Mean defect length was 3.9 cm. Five of 9 patients had ancillary procedures including rectus abdominis (n = 3), omental or gracilis (both n = 1) flap harvests. No intraoperative complications occurred. Median operative time was 377 minutes, blood loss was 200 mL, and length of stay was 2 days. Postoperative 30-day complications included urinary tract infection, epididymitis, anemia, recurrent stricture, and small bowel obstruction requiring surgery (all n = 1). Median follow-up was 11.7 months. CONCLUSION: Buccal mucosa grafts with ancillary maneuvers such as flap interposition or adjacent tissue transfer in robotic lower tract reconstruction is durable, safe, and comparable to open approaches.

"Postulating Penis: What Influences the Interest of Transmasculine Patients in Gender Affirming Penile Reconstruction Techniques?"

BACKGROUND: The limitations of metoidioplasty and phalloplasty have been reported as deterrents for transgender and other gender expansive individuals (T/GE) desiring gender affirming surgery, and thus penile transplantation, epithesis, and composite tissue engineering (CTE) are being explored as alternative interventions. AIM: We aim to understand the acceptability of novel techniques and factors that may influence patient preferences in surgery to best treat this diverse population. METHODS: Descriptions of metoidioplasty, phalloplasty, epithesis, CTE, and penile transplant were delivered via online survey from January 2020 to May 2020. Respondents provided ordinal ranking of interest in each intervention from 1 to 5, with 1 representing greatest personal interest. Demographics found to be significant on univariable analysis underwent multivariable ordinal logistic regression to determine independent predictors of interest. OUTCOMES: Sexual orientation, gender, and age were independent predictors of interest in interventions. RESULTS: There were 965 qualifying respondents. Gay respondents were less likely to be interested in epithesis (OR: 2.282; P = .001) compared to other sexual orientations. Straight individuals were the least likely to be interested in metoidioplasty (OR 3.251; P = .001), and most interested in penile transplantation (OR 0.382; P = .005) and phalloplasty (OR 0.288, P < .001) as potential interventions. Gay and queer respondents showed a significant interest in phalloplasty (Gay: OR 0.472; P = .004; Queer: OR 0.594; P = .017). Those who identify as men were more interested in phalloplasty (OR 0.552; P < .001) than those with differing gender identities. Older age was the only variable associated with a decreased interest in phalloplasty (OR 1.033; P = .001). No demographic analyzed was an independent predictor of interest in CTE. CLINICAL IMPLICATIONS: A thorough understanding of patient gender identity, sexual orientation, and sexual behavior should be obtained during consultation for gender affirming penile reconstruction, as these factors influence patient preferences for surgical interventions. STRENGTHS AND LIMITATIONS: This study used an anonymous online survey that was distributed through community channels and allowed for the collection of a high quantity of responses throughout the T/GE population that would otherwise be impossible through single-center or in-person means. The community-based methodology minimized barriers to honesty, such as courtesy bias. The survey was only available in English and respondents skewed young and White. CONCLUSION: Despite previously reported concerns about the limitations of metoidioplasty, participants ranked it highly, along with CTE, in terms of personal interest, with sexual orientation, gender, and age independently influencing patient preferences, emphasizing their relevance in patient-surgeon consultations.

Robotic-Assisted Testicular Autotransplantation.

Silber and Kelly first described the successful autotransplantation of an intra-abdominal testis in 1976. Subsequent authors incorporated laparoscopy and demonstrated the viability of transplanted testes based on serial postoperative exams. We sought to extend this experience with use of the da Vinci surgical robot, thereby demonstrating a novel robotic technique for the management of cryptorchidism. The procedure was performed for an 18-year-old male with a solitary left intra-abdominal testis. Following establishment of pneumoperitoneum, the robot is docked with four trocars oriented towards the left lower quadrant. Testicular dissection is carried out as shown. The gonadal and inferior epigastric vessels are isolated and mobilized; once adequate length is achieved, the former is clipped and transected, and the testicle and inferior epigastric vessels are delivered out of the body. The robot is then undocked and exchanged for the operating microscope. Arterial and venous anastomoses are completed with interrupted and running 9-0 Nylon, respectively, and satisfactory re-anastomosis is confirmed visually and with Doppler. The transplanted testicle is then fixed inferiorly and laterally within the left hemiscrotum, and all incisions are closed. We note that intraoperative testicular biopsy was not performed, for three reasons: (1) to avoid further risk to an already tenuous, solitary organ, (2) because our primary aim was to preserve testicular endocrine function, and (3) because the presence of ITGCN would neither prompt orchiectomy nor obviate the need for ongoing surveillance via periodic self-examination and ultrasonography. The patient is maintained on bed rest for two days and discharged on postoperative day seven in good condition. Over one year since autotransplantation, his now intra-scrotal testicle remains palpable and stable in size. Serum testosterone is unchanged from preoperative measurements. Robotic-assisted testicular autotransplantation is a feasible and efficacious management option for the solitary intra-abdominal testis.

Robotic Assisted Repair of Post-Ileal Conduit Parastomal Hernia: Technique and Outcomes.

OBJECTIVE: To describe a novel method of robotic assisted laparoscopic parastomal hernia repair (RAL-PHR), including the evolving use of the Da Vinci Single Port (SP) robotic system. METHODS: Demographic, intraoperative, and postoperative variables were collected for patients who underwent RAL-PHR. The technique for RAL-PHR utilizes a 3 cm incision in the contralateral upper quadrant for the robotic trocar and a 12 mm assistant port. The hernia sac is freed from the fascial defect. Dual Surface Mesh is approximated to the fascial edges with a portion excised to tailor the conduit. RESULTS: Four patients underwent RAL-PHR and three utilized the SP robot. Median age was 74.4 (range: 69.0-76.9) and median BMI 28.6 (26.5-43.2). All patients underwent cystectomy for bladder cancer and median time from index operation to parastomal hernia repair was 47.3 (40.4-11.48) months. Concurrent operations to hernia repair included ureteroenteric stricture repair, panniculectomy, abdominal wall reconstruction, stoma revision, and incisional hernia repair. Median operative time was 3.9 (2.6-8.7) hours including concurrent operations, median EBL was 50 (10-100) cc, mesh used in 3 cases, with no intraoperative complications reported. Median length of stay was 1 day and 1 post-operative complication greater than Clavien 2 reported. At median follow up of 18.3 (3.63-38.3) months, no recurrences were reported and 1 patient had undergone stoma dilation in the OR. CONCLUSION: RAL-PHR using the SP system maximizes advantages of laparoscopic repair while allowing for flexibility to perform concurrent procedures and safer takedown of adhesions through just two incisions. RAL-PHR is a safe and effective alternative to open and laparoscopic parastomal hernia repair with several additional benefits.

Robotic-assisted genitourinary reconstruction: current state and future directions.

With the widespread dissemination of robotic surgical platforms, pathology previously deemed insurmountable or challenging has been treated with reliable and replicable outcomes. The advantages of precise articulation for dissection and suturing, tremor reduction, three-dimensional magnified visualization, and minimally invasive trocar sites have allowed for the management of such diverse disease as recurrent or refractory bladder neck stenoses, and radiation-induced ureteral strictures, with excellent perioperative and functional outcomes. Intraoperative adjuncts such as near-infrared imaging aid in identification and preservation of healthy tissue. More recent developments include robotics via the single port platform, gender-affirming surgery, and multidisciplinary approaches to complex pelvic reconstruction. Here, we review the recent literature comprising developments in robotic-assisted genitourinary reconstruction, with a view towards emerging technologies and future trends in techniques.

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.

Bladder management in children with transverse myelitis.

BACKGROUND: Patients with transverse myelitis (TM) often present with urinary retention. While many recover their bladder function, some have persistent voiding dysfunction, and both intermediate and long-term outcomes are variable. OBJECTIVE: In patients who develop urinary retention requiring clean intermittent catheterization (CIC) at onset of TM, we sought to assess factors associated with improved voiding function and the risk of requiring persistent CIC over time. STUDY DESIGN: We reviewed children evaluated at our institution for TM from April 1998 to October 2018. Patients were included if they required CIC at initial presentation of TM. Demographics, initial and follow up neurologic exams were evaluated for their association with a return to baseline volitional voiding after requiring catheterization upon diagnosis of TM, with or without medical therapy. RESULTS: Among the 78 patients who presented with TM during the study period, 43 patients required CIC, with median follow up of 2.7 years. When evaluating for demographic or sensorimotor features associated with improvement to baseline voiding function in patients who initially required CIC, preserved lower extremity reflexes at presentation was the only significant prognostic factor (p < 0.05). Additionally, having complete lower motor neurologic recovery was associated with volitional voiding (p < 0.05). Among the 43 patients who were initially catheterizing, 27/43 (62%) were volitionally voiding at median follow up of 7 months from initial presentation, while the remaining 16/43 remained on CIC for a median follow up of 3.6 years. The cumulative risk of remaining on CIC was 60%, 47%, and 42% at 1, 5, and 10 year follow up, respectively, though there was not a significant difference in the rate of bladder recovery if patients had preserved reflexes. DISCUSSION: In children with TM who initially developed urinary retention, intact reflexes at presentation were associated with urologic recovery. Additionally, complete neurologic recovery was associated with volitional voiding. While 62% were volitionally voiding at most recent follow-up, the cumulative incidence of dependence on CIC within the first year of diagnosis was 60%, with a relatively few patients regaining volitional voiding by 10 years of follow-up. CONCLUSION: Among those initially evaluated for urinary retention in the setting of transverse myelitis, intact lower extremity reflexes on physical exam was associated with improved voiding function at most recent follow-up. However, more than half the patients on CIC at initial presentation required CIC at one year of follow-up. Careful, long-term monitoring of voiding status in patients with TM is recommended, even with improvement of neurological status.

Robotic Peritoneal Flap Revision of Gender Affirming Vaginoplasty: a Novel Technique for Treating Neovaginal Stenosis.

OBJECTIVES: To present the technique and early outcomes of salvage neovaginal reconstruction using robotic dissection and peritoneal flap mobilization. METHODS: Twenty-four patients underwent robotic peritoneal flap revision vaginoplasty from 2017 to 2020. A canal is dissected between the bladder and rectum towards the stenosed vaginal cavity, which is incised and widened. Peritoneal flaps from the posterior bladder and pararectal fossa are advanced and sutured to edges of the stenosed cavity. Proximal peritoneal flap edges are approximated to form the neovaginal apex. Patient demographics, comorbidities, surgical indications, and operative details are described. Outcome measures include postoperative neovaginal dimensions and complications. RESULTS: Mean age at revision was 39 years (range 27-58). All patients had previously undergone PIV, with revision surgery occurring at a median 35.3 months (range 6-252) after primary vaginoplasty. Surgical indications included short or stenotic vagina or absent canal. Average procedure length was 5 hours. At mean follow up of 410 days (range 179-683), vaginal depth and width were 13.6 cm (range 10.9-14.5) and 3.6 cm (range 2.9-3.8), respectively. There were no immediate or intraoperative complications related to peritoneal flap harvest. No patient had rectal injury. One patient had post-operative canal bleeding requiring return to the operating room for hemostasis. CONCLUSIONS: Robotic peritoneal flap vaginoplasty is a safe, novel approach to canal revision after primary PIV with minimal donor site morbidity.

Clinical Outcomes of a Combined Robotic, Transabdominal, and Open Transperineal Approach for Anastomotic Posterior Urethroplasty.

Background: Robotic pelvic surgery is being increasingly utilized for reconstruction proximal to the genitourinary diaphragm. We describe a combined robotic, transabdominal, and open transperineal approach for complex anastomotic posterior urethroplasty. Materials and Methods: We performed a multi-institutional retrospective study of patients who underwent anastomotic posterior urethroplasty by a combined robotic, transabdominal, and open transperineal approach between January 2012 and December 2018. Patient demographics; preoperative, intraoperative, and postoperative clinical data; and complications were reviewed. Urethroplasty success, de novo stress urinary incontinence (SUI), and de novo erectile dysfunction (ED) were evaluated. Results: Twelve patients were identified with a mean follow-up of 596 (range 73-1618) days. Mean patient age was 65.9 (range 53.4-76.8). Reconstruction required corporal splitting, prostatectomy, and gracilis muscle flap use in one (8.3%), eight (66.7%), and four (33.3%) patients, respectively. Postoperative urinary leak, thromboembolic event, and wound abscess occurred in one (8.3%), one (8.3%), and two (16.7%) patients, respectively. Stenosis recurrence occurred in two patients (16.7%) at a mean 187.5 (20-355) postoperative days. De novo ED and de novo SUI were reported in two (16.7%) and four (33.3%) patients, respectively. Nine patients (75.0%) underwent placement of an artificial urinary sphincter at a mean interval of 359.2 (111-1456) days after the index procedure, with no subsequent erosion. Conclusions: Complex posterior urethroplasty by a combined robotic, transabdominal and open transperineal approach is associated with success and complications rates that are comparable to open techniques and may allow for adjunctive procedures such as prostatectomy. This technique allows for the reconstruction of posterior urethral stenoses that would otherwise have been managed conservatively or with urinary diversion.

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.

Propeller Flap Perineal Urethrostomy Revision.

OBJECTIVE: To describe a technique for perineal urethrostomy (PU) revision using a posterior thigh propeller flap for a complex repair at high risk for stenosis. METHODS: Our technique utilizes the consistent posterior thigh perforators for a local flap with ideal length and thickness for repair. The stenotic PU is incised. Potential flaps are marked around a perforator blood supply closest to the defect. The flap is then elevated and rotated on its pedicle with its apex placed directly in the defect. Absorbable sutures partially tubularize the flap apex at the level of the urethrotomy which is calibrated to 30 Fr. We subsequently monitored the patient's clinical progress. RESULTS: With 17 months of follow-up the patient is voiding well without complaint, reports improved quality of life with a patent PU. Post void residuals have been less than 100cc. The patient, who has had a long history of urinary tract infections requiring hospitalization, has only reported one infection during follow up which was treated as an out-patient. CONCLUSION: For challenging PU revisions a distant local propeller flap of healthy tissue outside the zone of injury is the ideal choice for length, thickness, and minimal morbidity resulting in excellent clinical results for our patient.

Balloon dilation performs poorly as a salvage management strategy for recurrent bulbar urethral strictures following failed urethroplasty.

BACKGROUND: The optimal management strategy for recurrent urethral stricture disease (USD) following urethroplasty remains undefined. We aim to evaluate the role and efficacy of endoscopic urethral balloon dilation in temporizing recurrent USD after failed urethroplasty. METHODS: Between 2007-2018 at our institution, 80 patients underwent balloon dilation procedures for bulbomembranous urethral strictures. Balloon dilation was performed with an 8-cm, 24-French UroMax Ultra™ balloon dilator, under direct vision, guided by a 16-French flexible cystoscope. Patients who underwent concomitant open or endoscopic urethral procedures were excluded. Treatment failure was defined as the need for subsequent surgical intervention for stricture recurrence. Stricture characteristics including etiology, length, location, severity stage, and prior surgical procedures were compared between patients with and without treatment failure. RESULTS: Failure cases were more likely to have strictures following urethroplasty (21/27, 78%) [vs. the no-failure group (27/53, 51%)]. Among the 27/80 (33.8%) failures with a median follow-up of 8.4 months (IQR, 3.9-22.5 months), median time to recurrence was 4 months (IQR, 2-12 months). These patients had a greater incidence of prior stricture intervention in general (P=0.01) and prior urethroplasty specifically (P=0.03). On multivariable analysis, the number of prior treatments specifically independently remained associated with treatment failure. Complications of balloon dilation were uncommon (6/80, 7.5%) and minor in nature. CONCLUSIONS: Endoscopic balloon dilation performs poorly as a salvage strategy after failed open urethral reconstruction in addition to prior urethral dilations.

An update on oxidized regenerated cellulose (fibrillar™) in reducing postoperative corporal bleeding following inflatable penile prosthesis surgery.

BACKGROUND: Scrotal hematoma formation is a dreaded complication of penile prosthesis surgery that increases patient pain and healthcare costs, as well the risk for eventual device infection and failure. The efficacy of hemostatic agents in reducing the incidence of scrotal hematoma development has not been extensively studied in urologic prosthetic surgery. In this paper we further evaluate our experience with oxidized regenerated cellulose (ORC; Surgicel Fibrillar™) as an adjunct to standard hemostatic practices in inflatable penile prosthesis (IPP) implantation. METHODS: From April 2016 onward, intracorporal ORC pledgets were placed during corporotomy closure in all patients undergoing IPP implantation or revision by a single surgeon using an identical surgical technique. Perioperative parameters and outcomes-primarily postoperative cumulative drain output, secondarily patient phone calls in the postoperative period-were compared among successive cases with ORC (April 2016 to February 2019) and without ORC (April 2013 to March 2016). RESULTS: A total of 274 men underwent IPP implantation during the study period; 175 (64%) had ORC included in their corporotomy closures. Median drain output was significantly reduced in the ORC patients relative to the non-ORC group (50 vs. 65 mL; P=0.0001). A significant reduction in patient-initiated phone calls regarding scrotal pain, swelling, or discomfort in the first 4 weeks following surgery was also observed in the ORC group (average 0.69 vs. 1.1 calls per patient; P=0.03). A total of 9 patients underwent IPP explantation during the study period, all due to device infection; 5 of these were in the ORC group, while 4 were in the non-ORC group (P=0.73). ORC use did not constitute any additional infection risk. CONCLUSIONS: Bilateral incorporation of ORC pledgets during corporotomy closure in IPP surgery significantly decreases postoperative scrotal drain output, a well-documented risk factor for scrotal hematoma formation.

Comparison of 3.5 cm and transcorporal cuffs in high-risk artificial urinary sphincter populations.

BACKGROUND: The transcorporal (TC) artificial urinary sphincter (AUS) has traditionally been utilized in high-risk patients with urethral atrophy or prior urethral erosion. The 3.5 cm AUS cuff has been developed for use in a similar population. We compared the outcomes of TC AUS and 3.5 cm cuff patients to assess whether the TC approach was protective against urethral complications. METHODS: We performed a retrospective review for all men who underwent TC AUS and 3.5 cm AUS implantation by a single surgeon from 2007 to 2018 at a tertiary medical center. Demographic and outcomes data were collected and analyzed after database review to evaluate for rates of urethral erosion. Multivariate logistic regression was performed to identify co-morbid factors associated with urethral erosion. RESULTS: In our database of 625 AUS patients, we identified 59 (9%) men with TC AUS and 168 (27%) having a 3.5 cm cuff. Over a median follow-up time of 49 months, 28 (47%) men with TC cuffs developed urethral erosion compared with 25 (15%) men with a 3.5 cm cuff. On univariate analysis, a TC cuff was associated with increased odds of erosion (OR 6.65, 95% CI: 3.20-14.4, P<0.0001) when compared with a 3.5 cm cuff. On multivariate analysis, TC cuffs continued to portend significantly increased odds of cuff erosion. CONCLUSIONS: With longer follow up, TC AUS may not be as protective against urethral complications as previously described.
