Self-Expanding Wallstent Endoprosthesis for Malignant Ureteral Obstruction

Abstract

We present our experience with the self-expanding Wallstent endoprosthesis for ureteral recanalization in obstructive uropathy secondary to malignant pelvic disease. In total, 19 stents were inserted in 14 ureters. The follow-up included 100% of the patients. To date, except for one case, the patency of the stent has always persisted for the period of the survival of the patients, the longest ones being 4 and 4.1 years.
