Bilateral Giant Hydronephrosis in a Ten-Year-Old Male.

We describe a ten-year-old male with bilateral giant hydronephrosis due to pelviureteric junction obstruction presenting with abdominal distension and renal failure. The diagnosis was confirmed on computed tomography and required a two-stage procedure, initially percutaneous nephrostomy followed by Anderson-Hynes pyeloplasty with recovery of kidney function.
