Materials & Methods: A total of 49 females with urethral diverticulum who underwent transvaginal urethral diverticulectomy from October 2011 to December 2019 were included. Postoperative complications after transvaginal urethral diverticulectomy, complication-free period of each complication, and the treatment for the complications and their outcomes were investigated by reviewing the medical records of the patients. Results: The mean age of the patients at the time of urethral diverticulectomy was 52.71 ± 9.53 years. Postoperative complications that occurred after transvaginal urethral diverticulectomy were de novo stress urinary incontinence (SUI), recurrence, mild urethral stricture, and operation site infection and bleeding. De novo stress urinary incontinence was occurred in 5 (10.20%) patients within a month postoperatively. Submucosal macroplastique injection at proximal urethra was performed in all patients, and de novo SUI was cured in 1 and improved in 3 patients. The diverticulum recurred in 7 (14.29%) at the mean of 14.14 ± 17.21 months postoperatively. Second transvaginal urethral diverticulectomy was performed in 6 patients and 5 were cured. However, 1 recurred again and was cured after third transvaginal urethral diverticulectomy. Mild urethral stricture was presented in 2 (4.08) within a month postoperatively, and were improved after urethral dilatation using Hegar dilatator. Operation site infection and bleeding were observed in 2 (4.08%) and 1 (2.04%), respectively, within a month after the surgery. Patients with infection and bleeding were successfully cured by intravenous antibiotics and conservative management, respectively (Table 1). Conclusion: Postoperative complications after transvaginal urethral diverticulectomy can be effectively managed with a proper treatment. keywords : transvaginal urethral diverticulectomy, complication, treatment
