title: [A quiet revolution: the Wallstent urethral prosthesis (Urolume AMS)].
abstract: 14 patients (mean age: 57 years) with posterior urethral stricture were treated by internal urethrotomy and implantation of one or several Wallsten prostheses. The stent had to be removed in 2 patients (15%), while 12 patients (85%) obtained satisfactory urethral patency (mean follow-up: 17.5 months). Complications were observed in 50% of cases. They were able to be treated endoscopically with a satisfactory result in 5 out of 6 cases (intraprosthetic calculi or stenosis of the ends of the stent; 2 patients who became incontinent after insertion of the stent regained normal continence after insertion of an artificial sphincter above the stent. The Wallsten endoprosthesis therefore appears to be a very satisfactory treatment for recurrent complex strictures of the posterior urethra.
