Endoscopic management of a type IV syringocele causing massive perirenal urinoma in an infant.

The finding of a urinoma in the fetal and neonatal period is almost always related to an obstruction distal to the collection itself. Syringocele is a congenital or acquired dilation of a bulbourethral Cowper's gland. An exceedingly rare case of neonatal anterior urethral obstruction caused by a syringocele and manifesting itself with a dramatic clinical onset is presented. Clinical and radiologic findings are discussed and minimally invasive therapeutic strategies emphasized.
