Vesicoureteral reflux in women with primary bladder diverticulum

In 22 years we treated 271 adults, including 149 women, for vesicoureteral reflux. We describe our management of vesicoureteral reflux in 12 women between 18 and 58 years old who had an associated primary vesical diverticulum. A vesical diverticulum located near the ureteral orifice caused reflux by destroying the ureterovesical valve in 11 of these 12 patients. In 1 woman a bladder diverticulum distant from the ureteral orifice acted as a reservoir of chronic infection, which perpetuated reflux in a marginally competent ureterovesical junction. The reflux disappeared after excision of the diverticulum. Reflux was bilateral in 3 and unilateral in 9 cases. Symptoms of acute pyelonephritis were noted in 3 women and radiographic changes of chronic pyelonephritis were noted in 4. Urinary infection was controlled successfully by medical management in 4 patients. Ureteral reimplantation after excision of the bladder diverticulum and repair of the bladder wall was successful in eradicating reflux in 5 patients. Each patient was followed for 3 or more years.
