Vaginal mass caused by a lately recognized congenital bladder diverticulum.

Congenital bladder diverticula are strongly associated with vesicoureteral reflux (VUR), and are mostly present in childhood. The most common symptom is urinary tract infection at the time of admission. The diverticulum is usually solitary and its location is near the ureteral orifice, which is probably the main cause of VUR. We report a woman who presented with a vaginal mass located on the right inferior part of the external urethral meatus. The patient had a history of recurrent urinary tract infection and right nephrectomy due to VUR nephropathy. We examined her with cystography, computerized tomography, and cystoscopy. The cystoscopic examination was very diagnostic in our patient. The patient underwent diverticulectomy, and after 6 months of follow-up, her complaints had completely disappeared.
