Percutaneous endopyelopyelotomy: endourological management of a bifid pelvis with ureteropelvic junction obstruction.

A patient with a bifid renal pelvis and a severely stenotic ureteropelvic junction was managed successfully by creating a fistula between the 2 renal pelves with a direct vision urethrotome, and intubating the fistula with a circle tube and a universal stent for 6 weeks. This endourological procedure spared this obese diabetic patient from an open operation.
