Urinoma drainage for neonatal respiratory insufficiency.

This report describes two newborn males with posterior urethral valves, perirenal urinomas and respiratory distress. A 400 cc urinoma was drained percutaneously with resolution of respiratory symptoms in the first case. A 120 cc urinoma was drained in the second case but the infant died of pulmonary hypoplasia at 22 h of age. This report emphasizes the importance of aspirating or draining the urinoma in an attempt to treat the newborn's respiratory insufficiency.
