The endourological techniques for upper urinary tract diseases have developed mainly for the endoscopic treatment of upper urinary tract stones. Only a few studies on endoscopic incision of ureteropelvic junction obstruction (endopyelotomy) has been reported up to now.
We incised primary ureteropelvic junction obstruction in 8 cases, with a rigid cutting instrument, percutaneously, by full thickness incision. There were 7 successful cases out of 8 (87.5%). No complication was seen in all cases. The longest follow-up is 13 months.
Since endopyelotomy does not disturb the ureteral blood supply, and the post-operative morbidity is much less than the conventional surgery, it seems to be a useful method for the treatment of ureteropelvic junction stenosis.
Because long-term results are not available, careful follow-up of the patients should be necessary.
