Bladder outlet obstruction after operation for ureterocele.
Two patients with ureterocele-induced bladder outlet obstruction are presented. In each instance, a broad-based diverticulum had developed in the floor of the bladder as a result of the muscular defect created by a simple ureterocele in one patient and an ectopic ureterocele in the other. This bladder diverticulum produced secondary obstruction of the bladder outlet during the act of voiding. Urinary diversion in one patient had been carried out because of bladder outlet obstruction and was being seriously considered in the other patient because of upper tract deterioration. After the correct diagnosis was established, reconstruction of the muscular defect eliminated the obstruction and reestablished satisfactory bladder function. Urinary diversion was thus prevented in one patient and undiversion accomplished in another, when the true obstructing nature of the bladder diverticulum was established and correct therapy instituted.
