Simple vs complex urethral diverticulum: presentation and outcomes.

Objective: To determine whether complex anatomic configurations of urethral diverticula (UD), namely circumferential UD (cUD), present differently or confer a worse prognosis as compared with simple UD (sUD).

Methods: After institutional review board approval, a retrospective review of patients who underwent transvaginal urethral diverticulectomy at a single institution over an 8-year period was performed. A total of 43 patients were identified, of which 11 were found to have cUD.
