Transurethral resection of posterior urethral valves

Abstract

Posterior urethral valves (PUV) are the most common cause of lower urinary tract obstruction in boys with an incidence of 1.6-2.1 per 10,000 births. Most valves appear as leaflets arising from the verumontanum that fuse anteriorly. PUV during fetal development results in detrusor hypertrophy with high storage and voiding pressures. PUV may lead to dilation of the posterior urethra, bladder neck hypertrophy, bladder wall thickening, vesicoureteral reflux (VUR), upper tract dilation, and – in one third of affected patients – end-stage renal disease [1].
