Urethral duplication is a genitourinary anomaly that may rarely present in conjunction with posterior urethral valves. The management algorithm of children affected by both these urologic conditions is still unknown, given the low incidence and the complexity of each of these conditions. We present our clinical experience with the management of a child with Y-type urethral duplication and poste...

MATERIALS AND METHODS Questionnaires were mailed to patients 18 years and older treated at our institution for posterior urethral valves. Of the 124 patients 68 (64.2%) participated, 18 were unavailable and 38 did not partici...

In patients with posterior urethral valves (PUV), severe unilateral vesicoureteral reflux (VUR) is one of the three conditions associated with preservation of renal function.

AIMS To determine if detrusor glycogen content in a bladder after removal of a urethral obstruction reflects the situation of bladder dysfunction as it existed during the period of obstruction. METHODS The glycogen content of the detrusor was scored using a Periodic Acid Schiff's (PAS) staining. It was related to the functional history of the bladder. Bladder tissue was obtained from a guinea...

To evaluate the age and mode of presentation of patients with posterior urethral valves (PVU) in the antenatal and postnatal periods, we analyzed the files of 108 patients with the diagnosis of PUV in four referral hospitals in Riyadh, Saudi Arabia from 1989 to 1999. Of the study patients, 29 (27%) were antenatally discovered, 41 (38%) in the first year of life and 38 (35%) after the first year...
