Giant hydronephrosis is uncommon. It is a collection of urine of more than one liter in the excretory cavities in adults. We report a case of giant hydronephrosis in a 30-year-old woman, revealed by an abdominal mass associated with intermittent pain. This patient underwent a right nephro-ureterectomy and the cause was an obstruction of the right pyeloureteral junction.
