Diagnostic evaluation of neonatal ascites.

We present the case of a premature infant noted to have massive abdominal distension at birth. Obstetric ultrasound at delivery was significant for abdominal distension, oligohydramnios, and restricted chest wall motion. He was diagnosed to have posterior urethral valves with intraperitoneal rupture of the bladder. We present this case with a brief review of the literature.
