To determine the efficacy of retrograde endopyelotomy for the treatment of pelvi-ureteric junction (PUJ) obstruction using the Acucise ureteric balloon cutting catheter.Between February 1995 and July 1997, 13 consecutive patients with primary PUJ obstruction 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.The treatment was successful by objective criteria in eight of 13 patients and by subjective criteria in nine. The mean operative duration was 33 min (range 25-45) and all 13 patients were discharged within 24 h of the procedure. There were no major complications, such as vascular injury requiring transfusion. There were no delayed failures, as all failures occurred within 3 months of the procedure. Of the four total failures, two patients 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.In this small series. Acucise endopyelotomy was a safe procedure that offered effective, expeditious first-line treatment for PUJ obstruction. All failures occurred soon after treatment and did not hinder subsequent open pyeloplasty. Further studies with additional patients and a longer follow-up are warranted to determine the long-term efficacy of this promising new treatment.
