[Retrograde endopyelotomy in the treatment of iterative stenoses 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 retrograde 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 one hand, on the systematic dilatation of the intramural portion of the ureter, and on the other hand, on the possible installation of a double pigtail stent a few weeks before endopyelotomy. We have noted no complication. The stay in hospital lasted 3 days in average (2 to 5 days). Clinical and radiological results include: 4 successes, 1 improvement and 1 failure. The average time elapsed is of 9 months (6 to 18 months). This technique, which has a proven feasibility, is a good alternative for this indication, in the absence of associated calculi and particularly in women. Its efficacy remains to be demonstrated by larger series with a longer follow-up.
