Closure of mouth of bladder diverticulum via endoscopic transvesico-transurethral approach.

We successfully treated bladder diverticula in two patients using the endoscopic transvesico-transurethral approach. The mouth of the diverticulum was closed in two layers under pneumobladder, using two percutaneous ports placed into the bladder as well as the urethral route. This operation was performed 2 to 3 months after the bladder outlet obstruction was relieved by transurethral resection or incision of the prostate. The patients were able to void with a minimum of residual urine. The endoscopic transvesico-transurethral approach provided satisfactory vision.
