[Treatment of ureteral stenoses with modelling catheter (12 Fr. caliber)].
We present the results achieved by catheter dilatation in 31 cases of ureteral strictures of different etiologies, using a large caliber (12 Fr) double pigtail catheter. The patients had a mean follow up of at least two years. The catheter was left indwelling for 2 1/2 months. The success rate was 74.2%, with few and unimportant complications. However, in 3 cases with strictures of a tuberculous etiology the long-term success rate dropped to 33.3%. The results indicate that ureteral stents of a caliber larger than that used normally, increase the success rate in dilatation of ureteral strictures.
