    Abstract:
    From July 1986, percutaneous endopyelotomy was performed on a total of 12 patients (13 kidneys) including 8 males and 4 females with ureteropelvic junction (UPJ) obstruction. Of the 13 kidneys, 9 had primary UPJ obstruction and 4 had secondary UPJ obstruction. A rigid urethrotome (cold knife) was employed in 12 cases and a flexible electorotome (hot knife) in one case. A stent ureteral catheter was placed for 3 to 31 weeks after the procedure. The outcome was evaluated by radiography and urodynamic examinations. A successful outcome was obtained in 8 of 9 kidneys with primary UPJ obstruction and in 1 of 4 kidneys with secondary UPJ obstruction. These findings suggest that percutaneous endopyelotomy is useful in the treatment of primary UPJ obstruction.
