Urinary Symptoms Before and After Female Urethral Diverticulectomy-Can We Predict De Novo Stress Urinary Incontinence?.

Abstract

Purpose: We assessed preoperative and postoperative urinary symptoms, and determined risk factors for de novo stress urinary incontinence after transvaginal urethral diverticulectomy. Material(s) and Method(s): We reviewed the case records of 25 consecutive women who had transvaginal urethral diverticulectomy. Urinary symptoms were documented before and after surgery with a structured history and examination pro forma. Demographic, clinical and imaging parameters were reviewed to determine any association with preoperative and postoperative symptoms as well as possible risk factors for postoperative stress urinary incontinence. Result(s): The most common presenting symptoms were urinary urgency and frequency (60%), and dyspareunia (56%). On physical examination the most common findings were a tender anterior vaginal wall mass (88%) and urethral discharge (40%). At a mean followup of 15.1 +/- 14.9 months (median 12) the rate of urgency-frequency symptoms and dyspareunia decreased significantly from 60% to 16% and from 56% to 8%, respectively. All the patients who had urge incontinence were cured of this symptom after the operation. De novo stress urinary incontinence developed in 4 patients (16%) postoperatively, and it was mild and only necessitated surgical treatment in 1 patient. A diverticulum larger than 30 mm and proximal urethral location were significant factors (p <0.05) for the development of de novo stress urinary incontinence. Conclusion(s): Irritative bladder symptoms are common in woman with urethral diverticulum and usually resolve after surgical excision. Stress urinary incontinence developed immediately after the operation, and had a significant association with a proximal urethral location and ultrasonically measured size greater than 30 mm. © 2008 American Urological Association.
