title: Hydronephrosis of infancy and childhood in Benin City, Nigeria.
abstract: The clinical and radiological features of 50 Nigerian children with hydronephrosis were studied. Posterior urethral valve obstruction was the causative lesion in 26 (52%) cases and 50% of these presented with neonatal ascites. Ureteropelvic junction obstruction was responsible for 5 (10%) cases of hydronephrosis and invariably presented with a palpable abdominal mass. The incidence of vesico-ureteral reflux during micturating cysto-urethrography in this series is lower than reported amongst Caucasian children.
