Transvaginal management of symptomatic complex urethral diverticula by definite closure of diverticula and robust reconstruction of the urethra

Background: Management of complex urethral diverticula (UDs) is challenging not only for the ostia detection and urethral reconstruction in surgery but also for the high risk of postoperative complications. We aimed to present the experience of surgical management for UDs by transvaginal partial diverticulectomy and urethral reconstruction. Methods: The database of medical record library was retrospectively searched for patients underwent partial diverticulectomy for symptomatic complex UDs. During the surgical procedure, the cystourethroscopy was firstly performed to locate the diverticular ostium. The surgeon exposed and opened the diverticulum along its maximum axis. The surgeon recorded the location of ostia where saline solution flowed out, when one assistant pressed suprapubic region to increase inner -pressure of bladder and urethra. We focused on definite closure of diverticular ostia and robust urethral reconstruction. Results: The present study included 39 patients with mean age of 45 years. There were 28 patients, 23 patients and 21 patients suffering from recurrent urinary infection, frequency and urgency. Ten patients had stress urinary incontinence. All of the 39 patients had complex UDs because of U-shaped diverticula (24/39) and circumferential diverticula (15/39). Multiloculated UDs were detected in 17 out of 39 patients. During the median follow-up time of 2.0 (1.0-12.0) years, there was no case of de novo urinary incontinence. However, 2 patients still had mild stress urinary incontinence without additional treatment. At postoperative 3 months, five patients had para-urethral cysts with the size ranging from 0.3 to 0.4 cm, which were absorbed in follow-up. Conclusions: The method of transvaginal partial diverticulectomy, definite closure of diverticular ostium, and layered reconstruction of the urethra is a feasible surgical alternative for UDs.
