Video - Posterior urethral valves

Posterior urethral valves (PUV), also referred to as congenital obstructive posterior urethral membrane, is a urologic disorder affecting boys where membranous folds obstruct the normal flow of urine. This leads to bladder outlet obstruction, causing high bladder pressure that causes vesicoureteral reflux. The reflux of urine back up into the ureters and kidneys leads to urinary stasis, which can lead to recurrent urinary tract infections; and hydronephrosis, which is the swelling of a kidney due to a buildup of urine. Treatment involves surgery and ablation of the membrane, which allows urine to flow through unobstructed.
