RESUMO
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.

211 percutaneous nephrostomies (PCN) have been performed on 189 patients under combined fluoroscopic and reel time ultra-sound guidance. 4 major complications occurred with consisted in one hemorrhage and 3 septicemias. Indication of the PCN was diagnostic in 35 cases and therapeutic in 176 cases. Decompression of pyelo-caliceal system (89 cases) among with 72 in emergency, drying of an urinary fistula (8 cases), balloon dilatation of benign ureteral stenoses (18 cases) and treatment of 60 renal stones (3 dissolutions and 57 extractions). Results showed the drying of the fistula in all cases, the long term success of the balloon dilatation in 50% cases and 80% success rate of stone extraction.
