Many patients are condemned to repeated urethral dilatations because of the poor efficacy of treatment for male urethral stricture. The authors have recently used a new urethral prosthesis: a metal-reinforced, meshed tube which opens in the urethra and maintains a it open allowing the urothelium to grow over. The prosthesis therefore becomes incorporated in the wall of the urethra. they have implanted this prosthesis in 21 patients with a mean age of 61 years, essentially in the bulbar urethra, for longstanding strictures measuring 5 to 35 mm and unresponsive to currently available treatments. The endoscopic insertion of the prosthesis is performed after dilatation. The mean follow-up is 9 months. The stricture was correctly treated in all patients (three patients required two sessions). The follow-up of these patients is short and the stability of these favourable results needs to be confirmed by a longer follow-up.
由于男性尿道狭窄的治疗效果不佳，许多患者不得不接受反复的尿道扩张术。作者最近使用了一种新型尿道假体：一种金属增强的网状管，它在尿道内张开并保持开放状态，使尿路上皮能够生长覆盖其上。因此，该假体被整合到尿道壁中。他们已将此假体植入21例平均年龄为61岁的患者体内，主要植入球部尿道，用于治疗长度为5至35毫米且对现有治疗无反应的长期狭窄。假体在内镜下于扩张术后插入。平均随访时间为9个月。所有患者的狭窄均得到了正确治疗（3例患者需要进行两个疗程）。这些患者的随访时间较短，这些良好结果的稳定性需要通过更长时间的随访来证实。
