Endopyelotomy for Ureteropelvic Junction Obstruction: Is Long-Term Stenting Mandatory?

Abstract

Percutaneous endopyelotomy by cold-knife urethrotome was used in the treatment of seven cases with ureteropelvic junction obstruction (UPJO) following pyelolithotomy (three cases), pyeloplasty (two cases), and open nephrostomy (one case). In the seventh primary UPJO was associated with a renal pelvic stone. Internal splinting for 5 weeks was used in two cases and for 4 days in five cases. With follow-up of 3 to 10 months, all cases had a satisfactory outcome.
