Excision and Primary Anastomosis for Isolated, Short, Anastomotic Strictures in Transmen

Urethroplasty Methods for Stricture Repair After Gender Affirming Phalloplasty: High Failure Rates in a Hostile Surgical Field

OBJECTIVE

To report our experience with 71 postphalloplasty urethral strictures in order to discuss the performance characteristics of different urethroplasty techniques in urethral stricture after phalloplasty.

METHODS

We conducted a retrospective chart review of 85 urethroplasties performed for stricture repair in 71 patients with phalloplasty for gender affirmation between August 2017 and May 2020. Stricture location, urethroplasty type, complication rate, and recurrence rate were recorded.

RESULTS

The most common stricture type was distal anastomotic (40/71, 56%). The most common initial repair type was excision and primary anastomosis (EPA) (33/85, 39%), followed by first-stage Johanson urethroplasty (32/85, 38%). The stricture recurrence rate after initial repair of all types was 52% (44/85). The recurrence rate of stricture after EPA was 58% (19/33). The recurrence rate after staged urethroplasty was 25% (2/8) for patients who successfully completed a first and second stage. 30% (3/10) of patients who completed a first stage and opted out of a second stage required a revision to achieve successful lifetime voiding from the surgical urethrostomy.

CONCLUSION

EPA after phalloplasty has a high failure rate. Nontransecting anastomotic urethroplasty has slightly lower failure rate, and staged Johanson-type surgeries have the highest success rates after phalloplasty.

Determining the outcomes of urethral construction in phalloplasty

OBJECTIVE

To evaluate the surgical and functional outcomes of urethral reconstruction associated with phalloplasty, depending on the surgical techniques and patient history.

MATERIALS AND METHODS

We conducted a single-centre retrospective study including 89 patients who underwent phalloplasty with urethral reconstruction between 2007 and 2018. Patients included were trans-male patients undergoing gender-affirming surgery and cis-male patients undergoing penile reconstruction after trauma, congenital malformation, or cancer. Urethral reconstructions were performed by free flap or skin graft (total or thin). Secondary urethroplasty may include direct vision urethrotomy, excision-anastomosis, or augmentation urethroplasty (skin graft, buccal mucosa graft). Patient demographics, medical history, peri- and postoperative data were collected from patient files. Functional results were evaluated using individual questionnaires.

RESULTS

The mean (±sd) follow-up duration was 5.5 (±3.7) years. No significant difference was found for total urethral complication rate (fistula and/or stricture) according to type of urethral construction (70.9% for free flap urethra vs 73.5% for skin graft urethra; P = 0.911), nor according to the patient's grounds for surgery (72.7% for cis-male vs 71.8% for trans-male patients; P = 1). A total of 36 patients (40.5%) answered the functional questionnaire, of whom 80.5% reported usually voiding while standing and 47.5% were comfortable with urinating in public.

CONCLUSIONS

Urethral construction in phalloplasty is associated with a high complication and revision rate regardless of the type of urethral reconstruction. Voiding in a standing position is generally possible but should not conceal feeble functional results.

Comparative study between thulium laser and cold knife visual urethrotomy for treatment of short bulbomembranous urethral stricture

INTRODUCTION

The classical way to treat urethral stricture is the direct vision cold knife internal urethrotomy (DVIU). Along with advances in laser technology, laser urethrotomy is widely used, such as neodymium-doped yttrium aluminum garnet, argon, potassium titanyl phosphate, and thulium laser. We aimed to compare thulium laser urethrotomy (TLU) and cold knife visual urethrotomy (CKVU) in terms of short bulbomembranous urethral stricture management.

MATERIALS AND METHODS

This prospective interventional study was conducted for 24 months, from January 2018 to January 2020, on 60 patients with primary short bulbo-membranous urethral stricture who came to the Department of Urology of Al-Azhar University Hospital, New Damietta, Egypt. We divided these patients into 2 age-matched groups; 30 patients treated with CKVU and 30 patients with TLU.

RESULTS

Regarding efficacy, postvoid residual urine volume (PVR) was reduced significantly in both groups (P < .001) after 6 months of follow-up; however, the reduction in TLU was greater than CKVU (P = .008). The improvement of Qmax after 6 months was significant and comparable in both groups. Regarding the quality of life, both groups showed a significant (<0.05) improvement in international prostate symptom score (IPSS) and the Male Sexual Health Questionnaire (MSHQ) scale, without no significant difference between both groups (>0.05). TLU showed a significantly (P = .038) shorter operative duration (24 ± 4.17 min) than CKVU duration (33 ± 4.86 min). Compared with CKVU, TLU was associated with less blood loss during surgery (P = .001), lower recurrence rate (46.7% vs. 19.97%, respectively), and lower frequencies of urethral dilatation (P = .001).

CONCLUSION

TLU is an effective and safe therapy for managing bulbomembranous urethral strictures, with a relatively low recurrence rate. Further investigations of other techniques are recommended to look for the most appropriate procedure to combat the urethral stricture problem.

Treatment of Urethral Strictures in Transmasculine Patients

Background: Urethral strictures are a common complication after genital gender-affirming surgery (GGAS) in transmasculine patients. Studies that specifically focus on the management of urethral strictures are scarce. The aim of this systematic review is to collect all available evidence on the management of urethral strictures in transmasculine patients who underwent urethral lengthening. Methods: We performed a systematic review of the management of urethral strictures in transmasculine patients after phalloplasty or metoidioplasty (PROSPERO, CRD42021215811) with literature from PubMed, Embase, Web of Science and Cochrane. Preferred Reporting Items for Systematic reviews and Meta-Analysis-(PRISMA) guidelines were followed, and risk of bias was assessed for every individual study using the 5-criterion quality appraisal checklist. Results: Eight case series were included with a total of 179 transmasculine patients. Only one study discussed the management of urethral strictures after metoidioplasty. Urethral strictures were most often seen at the anastomosis between the fixed and pendulous urethra. For each stricture location, different techniques have been reported. All studies were at a high risk of bias. The current evidence is insufficient to favor one technique over another. Conclusions: Different techniques have been described for the different clinical scenarios of urethral stricture disease after GGAS. In the absence of comparative studies, however, it is impossible to advocate for one technique over another. This calls for additional research, ideally well-designed prospective randomized controlled trials (RCTs), focusing on both surgical and functional outcome parameters.

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.

Surgical outcomes and proposal for a treatment algorithm for urethral strictures in transgender men

OBJECTIVES

To assess our results of surgical treatment for urethral strictures in transgender men, and to provide a surgical treatment algorithm.

PATIENTS AND METHODS

A single centre, retrospective cohort study was conducted of transgender men who underwent surgical correction of their urethral stricture(s) between January 2013 and March 2020. The medical charts of 72 transgender men with 147 urethral strictures were reviewed. The primary outcomes were the success and recurrence rates after surgical treatment for urethral strictures.

RESULTS

The median (interquartile range [IQR]) follow-up was 61 (25-202) months. At last follow-up, 50/72 (69%) were able to void while standing (after one [60%], two [20%], three [6%], four [8%], five [4%], or seven [2%] procedures), 10/72 (14%) await further treatment, two of the 72 (3%) sat to void despite good urodynamic function, and 10/72 (14%) had a definitive urethrostomy. Of 104 surgical treatments included in separate success rate analysis, 65 (63%) were successful (43/75 [57%] after phalloplasty, 22/29 [76%] after metoidioplasty). The highest success rates in short urethral strictures were seen after a Heineke-Mikulicz procedure (six of seven cases), and in longer or more complicated urethral strictures after two-stage with graft (four of six), two-stage without graft (10/12), pedicled flap (11/15, 73%), and single-stage graft (seven of seven) urethroplasties. Grafts used were buccal mucosa or full-thickness skin grafts. Success rates improved over time, with success rates of 38% and 36% in 2013 and 2014, to 71% and 73% in 2018 and 2019, respectively. We concluded with a surgical treatment algorithm based on previous literature, stricture characteristics, and our surgical outcomes.

CONCLUSION

The highest success rates were seen after a Heineke-Mikulicz procedure in short urethral strictures; and after graft, pedicled flap, or two-stage urethroplasties in longer or more complicated urethral strictures. Finally, most of the transgender men were able to void while standing, although in some multiple surgical procedures were necessary to accomplish this.
