RETROGRADE ENDOPYELOTOMY FOR THE TREATMEN T OF ITERATIVE STENOSIS OF THE PYELOURETERAL JUNCTION

This work is a report on our preliminary experience with the treatment of iterative stenosis of the pyeloureteral junction (JPU) through a r etrograde endoscopic approach. From June, 1991, to June, 1992, we used this method to operate 6 cases of failed surgical pyeloplasty due to abnormalities of the JPU. The success of this operation depends, on on e hand, on the systematic dilatation of the intramural portion of the ureter, and on the other hand, on the possible installation of a doubl e pigtail stent a few weeks before endopyelotomy. We have noted no com plication. The stay in hospital lasted 3 days in average (2 to 5 days) . Clinical and radiological results include : 4 successes, 1 improveme nt and 1 failure. The average time elapsed is of 9 months (6 to 18 mon ths). This technique, which has a proven feasibility, is a goood alter native for this indication, in the absence of associated calculi and p articularly in women. Its efficacy remains to be demonstrated by large r series with a longer follow-up.
