[Giant hydronephrosis: conservative treatment by endopyelotomy].

A case of giant hydronephrosis in the right kidney and inferior pelvis of the left kidney in a 60-years-old female patient with nonspecific abdominal symptoms and signs is reported. Because involvement was bilateral and the patient insisted on conservative treatment, we performed a bilateral percutaneous endopyelotomy. The excellent results achieved were demonstrated by ultrasound. This however was not true for the functional results due to the irreversible renal lesion.
