[Treatment of ureteral stenosis complicated by endourethral prosthesis. Long-term results]

To evaluate the long-term results obtained in the treatment of urethral stenosis complicated with urethral endoprosthesis.

Between March 1991 and December 1996, 40 endourethral prosthesis were implanted in 36 patients; 2 prosthesis were placed in 4 patients. Of the 40 prosthesis implanted, 37 were UroLume and 3 Ultraflex. All, with the exception of 2, were patients with recurrent stenosis after earlier failures of prior internal urethrotomy and/or repeat urethral dilations.

Immediate post-operative symptomatic relief was achieved in 97.2% patients. Only one patient required removal of the endoprosthesis. In 4 patients (11.1%) urethral restenosis develop distal or proximal to the endoprosthesis. No patient developed restenosis due to endoprosthetic fibrosis.

The long-term results obtained in the treatment of bulbar urethral stenosis complicated with endoprosthesis demonstrate the efficacy and stability over time of this technique, which shows a low complications rate when patients are strictly selected.
