Abstract

Hypothesis / aims of study
Phalloplasty with concomitant vaginectomy is an increasingly common gender-affirming procedure. Given the complexity and high urologic complication profile, recent studies have begun to examine rates of post-phalloplasty voiding dysfunction – with urethral stricture, meatal stenosis, and urethral fistula being the most commonly documented [1]. Although the complications of this surgery have been well documented, there have been limited investigations specifically on management of post-operative urinary incontinence (UI) [1-3].
Study design, materials and methods
We offer a review of current literature on incontinence after phalloplasty and present the key steps and novel decision-making process in a 30-year-old transgender male who developed significant stress-predominant UI after phalloplasty and vaginectomy.
Results
Informed consent was obtained prior to each procedure. A 30-year-old transgender male initially underwent a radial forearm free flap phalloplasty with concomitant urethral lengthening, vaginectomy, scrotoplasty, and perineoplasty. Post operatively, he developed a urethral stricture of the pars pendulans followed by a non-fistulous fluid collection in the vaginal cavity remnant. He subsequently underwent a drainage and sharp excision of this remnant vaginal cavity lining with a concomitant first stage Johansen urethroplasty and perineal urethrostomy. Immediately post-procedure, he developed new, significant, stress-predominant mixed UI. Video urodynamics demonstrated large volume stress UI with an abdominal leak point pressure of 0. Cystogram showed an open bladder neck at rest [Figure 1]. His UI was suspected to be due to lack of anterior vaginal wall support with subsequent ‘dropping’ of the bladder neck and proximal urethra. Given patient desire to avoid any major surgery, urethral bulking with polyacrylamide gel was initially employed with very minor improvement. 4-months later he underwent urethral mobilization and urethropexy. This provided only transient symptom relief. After careful consideration, 4-months after urethropexy, the patient underwent a pubovaginal sling via a perineal approach with autologous rectus fascia without complication.
Interpretation of results
Current literature on the development and management of UI after phalloplasty is scarce with only two prior studies identified [2,3]. Hoebeke et al and Zhang et al reported rates of UI ranging from 50-59%. However, unlike our patient, both studies reported only mild UI or post void dribbling, related to lack of neourethra musculature, which did not warrant further intervention.
Concluding message
Our study is the first to report on a comprehensive review and utilization of an autologous pubovaginal facia sling in the management of severe UI after phalloplasty. Despite the absence of a vaginal cavity, a pubovaginal sling can be performed in transgender males for stress UI. Perineal urethrostomy is helpful, but may not be necessary. This case highlights the need for further research in this growing, complex, patient population with altered anatomy and significant disparities to care. At present date, the patient is doing well with notable improvement in his continence and has normal bladder emptying.
