Prenatal percutaneous antegrade pyelography in posterior urethral valves: sonographic guidance

Posterior Urethral Valves: Renal Failure and Prenatal Treatment

Posterior urethral valves occur in 1 : 5000 live births. Despite the high prevalence, the few children that survive do poorly, with over 50% progressing to ESRD in 10 years. The gold standard for post-natal diagnosis is voiding cystourethrography, while pre-natal diagnosis is dependent on routine screening ultrasonography. Despite the ability to identify features of bladder outlet obstruction e...

Posterior Urethral Valves

The most common cause of lower urinary tract obstruction in male infants is posterior urethral valves. Although the incidence has remained stable, the neonatal mortality for this disorder has improved due to early diagnosis and intensive neonatal care, thanks in part to the widespread use of prenatal ultrasound evaluations. In fact, the most common reason for the diagnosis of posterior urethral...

Current Practice Posterior urethral valves

Posterior urethral valves (PUV) are the commonest cause of bladder outlet obstruction in children. With improvement of primary health care and widespread use of ultrasonography during antenatal check-up, early diagnosis of PUV has increased. The first description of PUV was made in 1919 by Hugh Hampton Young 1 . PUV represents a spectrum of severity, ranging from disease incompatible with postn...
