Abstract
Between 1983 and 1991 we performed 212 endopyelotomies on 110 cases of primary and 102 of secondary obstruction of the ureteropelvic junction. Of the 189 patients in the series 89% have been followed for a minimum of 6 months postoperatively, 63% for more than 3 years (3 to 8-year followup). Our overall success rate has been 86% with little difference being detected between the success that we have obtained with primary and secondary obstructions (85% versus 86%). Other variables, such as patient age, sex or side of obstruction, have little bearing on the outcome of the procedure. Endopyelotomy is passing the test of time as a safe and reliable means to correct ureteropelvic junction obstruction. Endopyelotomy should be the first choice for the correction of ureteropelvic junction obstruction in most patients.
