Congenital bladder perforation and urinary ascites caused by posterior urethral valves: a case report.

Abstract

Neonatal urinary ascites caused by bladder perforation is rare, with fewer than 20 cases reported in earlier literature. Congenital bladder perforation can be associated with bladder outlet obstruction such as posterior urethral valves, urethral atresia, presacral mass, and neurogenic dysfunction of the bladder. The bladder perforation in these cases is most commonly intraperitoneal, which leads to congenital urinary ascites. However, intrauterine perforation of the bladder in a newborn infant with posterior urethral valves is extremely rare, as is evident from the three cases in previous literature. The present case report describes an unusual case of congenital bladder perforation and urinary ascites caused by posterior urethral valves.
