VENTRAL ONLAY BUCCAL MUCOSA GRAFT URETHROPLASTY FOR FEMALE URETHRAL STRICTURE: MEDIUM-TERM RESULTS IN A SINGLE SURGEON EXPERIENCE.

To describe our own approach using buccal mucosal grafting and to assess the outcome of this approach. A total of 42 patients underwent ventral onlay BMG by a single surgeon between 2017 and 2022. A longitudinal incision along the length of the urethra was made through the anterior vaginal wall and the peri-urethral fascia was incised to create two flaps. This ventral urethrotomy ran from the meatus into the proximal health urethra above the level of the stricture. A buccal mucosal graft was harvested and sutured to the margins of the urethral mucosa itself and the flaps of peri-urethral fascia. The vaginal wall was then closed. The mean age of the patients was 53.6 ± 12.8 years. There were no perioperative or postoperative complications. At a mean follow-up of 38.1 months, 41 patients (98%) were stricture-free. Peak flow rate improved from a mean of 7.7 ± 3.2 ml/s preoperatively to 25.9 ± 5.9 ml/s postoperatively. No patient developed incontinence. One patient developed a recurrent urethral stricture which was treated by redo urethroplasty. The surgical technique applied has proved efficiency. The ventral BMG preserves the urethral sphincter and so avoids postoperative incontinence. The use of peri-urethral fascia represents a good vascular and mechanical support for the graft.
