Urinary Ascites Secondary to Bladder Perforation in a Neonate with Posterior Urethral Valves.

ABSTRACT

Neonatal urinary ascites is a rare condition. It can be spontaneous or iatrogenic. Posterior urethral valve is the most common cause of spontaneous urinary ascites. It occurs most commonly from the rupture of calyceal fornices secondary to raised intrarenal pressure. Rarely, urinary bladder perforation is responsible for urinary ascites in Posterior urethral valve. Urinary ascites should be considered in a neonate with ascites with unexplained renal failure. In this article, we present the imaging feature and brief review of literature of a child with urinary ascites secondary to Posterior urethral valve.
