A full-term male infant was antenatally diagnosed to have left hydronephrosis. Post natal ultrasonography (US) and diuretic renography confirmed the diagnosis of left pelvi-ureteric junction obstruction. His clinical course was complicated by one episode of urinary tract infection. Serial US and diuretic renography showed no improvement in the obstruction. The patient underwent an Anderson-Hynes pyeloplasty at nine months of age with no post-operative complications. The diagnosis and management of antenatally-diagnosed hydronephrosis are discussed.
