OBJECTIVE: To determine the efficacy of retrograde endopyelotomy for the treatment of pelvi-ureteric junction (PUJ) obstruction using the Acucise ureteric balloon cutting catheter. @entity1 AND METHODS: Between February 1995 and July 1997, 13 consecutive @entity1 with primary @entity4145 underwent Acucise endopyelotomy at our institution. The mean follow-up was 17.7 months (range 7-33). The success of the procedure was based on objective patency on follow-up diuretic isotopic renography and the subjective resolution of symptoms. RESULTS: The treatment was successful by objective criteria in eight of 13 @entity1 and by subjective criteria in nine. The mean operative duration was 33 min (range 25-45) and all 13 @entity1 were discharged within 24 h of the procedure. There were no major complications, such as @entity1317 requiring transfusion. There were no delayed failures, as all failures occurred within 3 months of the procedure. Of the four total failures, two @entity1 have successfully undergone open pyeloplasty and one other was found to have a crossing vessel at the lower pole at the time of the operation. CONCLUSION: In this small series. Acucise endopyelotomy was a safe procedure that offered effective, expeditious first-line treatment for @entity4145 . All failures occurred soon after treatment and did not hinder subsequent open pyeloplasty. Further studies with additional @entity1 and a longer follow-up are warranted to determine the long-term efficacy of this promising new treatment.
