Urethral strictures that are refractory to initial management present unique challenges to the reconstructive surgeon. Treatment trends have shifted as new tissue resources are becoming available. There is renewed interest in old methods as skill and technique have improved. We describe the scope of the surgical armamentarium available to develop creative approaches and successful outcomes.
We discuss techniques to maximize the availability of oral mucosa, harvest and use of rectal mucosa, and developments in tissue engineering. Evolving methods to assess success of repair are also described. Urethral reconstruction for refractory urethral strictures requires proficiency with multiple methods as these strictures often require combining techniques for successful treatment.
初始治疗难治的尿道狭窄给重建外科医生带来了独特的挑战。随着新的组织资源不断涌现，治疗趋势已经发生转变。由于技术和技巧的改进，人们对旧方法重新产生了兴趣。我们描述了可用于开发创新方法和取得成功结果的手术器械范围。
我们讨论了最大限度利用口腔黏膜的技术、直肠黏膜的采集和使用以及组织工程的进展。还介绍了评估修复成功的不断发展的方法。难治性尿道狭窄的尿道重建需要精通多种方法，因为这些狭窄通常需要联合技术才能成功治疗。
