We report two cases of neonatal ascites. The first case is a 24 day ol
d male nefered for abdominal distention and edema. Peritoneal tap remo

the urinary ascites and renal function normalizatiom Long term follow-
up after endoscopic resection of valves was good. The second case is a
male infant who presented at birth with abdominal distention. Radiolo
gy revealed an urinoma and a left side hydronephrosis secondary to ure
teropyelic junction syndrome which underwent a successful surgical tre
atment. Urinary ascites is a rare entity which calls for immediate dia
gnosis and management to preserve renal function,
