Abstract

Objective: To assess the presenting features and medium-term symptomatic outcomes in women having excision of urethral diverticulum with Martius labial fat pad (MLFP) interposition.

Patients and methods: We reviewed our prospective database of all female patients having excision of a symptomatic urethral diverticulum between 2007 and 2015. Data on demographics, presenting symptoms and clinical features were collected, as well as postoperative outcomes.

Results: In all, 70 women with a mean (range) age of 46.5 (24-77) years underwent excision of urethral diverticulum with MLFP interposition. The commonest presenting symptoms were a urethral mass (69%), urethral pain (61%), and dysuria (57%). Pre-existing stress urinary incontinence (SUI) was present in 41% (29) of the women. After surgery, at a mean (SD) of 18.9 (16.4) months follow-up (median 14 months), complete excision of urethral diverticulum was achieved in all the women, with resolution of urethral mass, dysuria and dyspareunia in all, and urethral pain in 81%. Immediately after surgery, 10 (24%) patients reported de novo SUI, which resolved with time and pelvic floor muscle training such that at 12 months only five (12%) reported continued SUI. There was one symptomatic diverticulum recurrence (1.4%).

Conclusions: The commonest presenting symptom of a female urethral diverticulum is urethral pain followed by dysuria and dyspareunia. Surgical excision with MLFP interposition results in complete resolution of symptoms in most women. The incidence of persistent de novo SUI in an expert high-volume centre is 12%.
