Objective To present our outcomes of ventral-onlay buccal mucosa graft (BMG) substitution urethroplasty in treating female urethral stricture (FUS). Patients and Methods We conducted a review of a prospectively collected database of 22 consecutive women (median [range] age 50 [34–72] years) with urethral stricture who underwent ventral onlay BMG substitution urethroplasty after June 2012 and who had a minimum follow-up of 6 months (median 21.5, range 6–51 months). Data were analysed for stricture recurrence, change in median maximum urinary flow rate (Qmax) and median post-void residual urine volume (PVR). Statistical analysis was performed using the Wilcoxon signed rank test, Student's t-test and the Mann–Whitney U-test. Results Freedom from stricture recurrence was achieved in 21/22 (95.5%) women. The median (range) Qmax significantly improved, increasing from 7 (3.5–11) to 18 (5–37) mL/s (P <0.05). The median (range) PVR was significantly reduced from 100 (0–300) to 15 (0–150) mL (P < 0.05). Short- and longer-term complication rates were low. One woman developed mild de novo stress urinary incontinence, which settled with conservative management by 6 months. Conclusions Early and medium-term results indicate that ventral onlay BMG substitution urethroplasty is an excellent treatment for FUS that can avoid the need for the repeat procedures regularly required after traditional endoscopic management.
