Unusual case of ascites secondary to unilateral distal ureteric obstruction in an infant.

Congenital obstructive uropathy is a rare cause of ascites in infants. Majority of reported cases of genitourinary causes of ascites were due to posterior urethral valve. Here, we report a 6-month-old boy who presented with progressive tense ascites and peritonitis attributed by unilateral left distal ureteric obstruction and acute pyonephrosis.
