Objectives: To report our experience of transvaginal diverticulectomy with pubovaginal sling placement in a series of 32 women with recurrent urethral pseudodiverticula.

Methods: A total of 32 women underwent surgical repair from January 2000 to June 2007. Of the 32 women, 12 had undergone other concomitant previous urethral surgery, predominantly for stress urinary incontinence. Transvaginal excision of the diverticulum and concomitant pubovaginal sling placement were performed routinely. The women were evaluated postoperatively for symptom relief, anatomic result, and postoperative continence status at 1, 6, and 12 months and annually thereafter. Pelvic magnetic resonance imaging was repeated after 1 year.

Results: The mean follow-up was 4.3 years. In all cases, the voiding urethrogram after catheter removal showed a good urethral shape with an absence of urinary leaks. At the postoperative urodynamic investigation, 27 patients had an unobstructed and 5 an equivocal Blaivas-Groutz nomogram. Three patients (20%) reported a persistent degree of stress urinary incontinence, including 2 with grade 1 stress urinary incontinence and 1 with mixed incontinence. Two patients presented with clinically evident diverticulum recurrence, and in 1 patient, an intraurethral diverticulum, was found at the 1-year magnetic resonance imaging examination.

Conclusions: A pubovaginal sling added routinely to all diverticulectomy procedures offers significant support to the urethral repair and/or prevention of urinary incontinence, including in recurrent cases, and does not increase the risk of erosion into the urethra or fistula formation.
