[Benign ureteral stenoses. Dilatation with an angioplasty balloon].
An angioplasty balloon was used to dilate 23 benign ureteral stenoses in 21 patients. The anterograde approach through percutaneous puncture of the kidney was used in 19 cases. Following dilatation, an 8 F to 24 F catheter was left in the ureter. Dilatation was successful in 13 out of 23 cases (56%) followed up for 1 month to 2 years. It failed in 8 cases, and 2 patients are undergoing ureteral remodelling. Thus, dilatation of benign ureteral stenoses after percutaneous renal puncture was effective in about 60% of the cases. The follow-up period is still too short for us to determine the indications of this technique according to the cause and duration of the stenosis.
