[Wallstent prosthesis, urethral stenosis, and prostatic nodular hyperplasia. Presentation of our experience].

The present paper reviews our experience in the use of Wallstent prosthesis. We contribute a total of seven patients which presented with bulbar urethra stenosis (five cases) and benign prostate hyperplasia (two cases), all of which had undergone periodical dilation prior to the prosthesis implant as well as various endoscopic urethrotomies. Here, we report the indications, exclusion criteria, criteria for evaluation of results, and brief description of the technique or method used for the prosthesis implant. Finally, we report on the procedure's advantages and the need to conduct extensive studies (prospective and randomized) in order to clarify the place such prosthesis may take within the therapeutic field of stenosis of the urethra, and in benign prostate hyperplasia.
