title: Major renal artery aneurysm as cause of hydronephrosis treated by renal preservation surgery.
abstract: We report a case of a giant renal artery aneurysm causing hydronephrosis that initially had erroneously been thought to be a renal cyst. Giant renal artery aneurysms greater than 10 cm in diameter are very rarely reported. The aneurysm was repaired successfully with kidney preservation and closure of the arterial fistula.
