Recurrent male anterior urethral stricture disease is a complex surgical challenge that should be managed by reconstructive urologists with experience in stricture management. Diagnosis of recurrence requires both anatomic narrowing and patient symptoms identified on validated questionnaires, with limited role for intervention in asymptomatic treatment "failures". Endoscopic management has a very specific role in recurrence, and the choice of technique for urethroplasty depends on pre-operative urethrography and cystoscopy. Surgical success depends on addressing patient concerns, complete stricture excision, tissue quality optimization, and the use of multi-stage repair when indicated. Augmentation with genital skin flaps and/or grafts is often required, with buccal mucosa as the ideal graft source if local tissue is compromised. Salvage options including urinary diversion and perineal urethrostomy must also be considered in debilitated patients with severe disease or repeated treatment failures. Unique patient populations including patients with hypospadias and lichen sclerosis are among the highest risk for repeated recurrence and require special care in surgical technique, graft selection, and post-operative management.
复发性男性前尿道狭窄疾病是一项复杂的外科挑战,应由在狭窄治疗方面有经验的重建泌尿外科医生来处理。复发的诊断需要解剖学上的狭窄以及在经过验证的问卷上确定的患者症状,对于无症状的治疗“失败”进行干预的作用有限。内镜治疗在复发中具有非常特定的作用,尿道成形术技术的选择取决于术前尿道造影和膀胱镜检查。手术成功取决于解决患者的担忧、完全切除狭窄、优化组织质量以及在必要时采用多阶段修复。如果局部组织受损,通常需要用生殖器皮瓣和/或移植物进行扩大,颊黏膜是理想的移植物来源。对于病情严重或反复治疗失败的体弱患者,还必须考虑包括尿流改道和会阴尿道造口术在内的挽救方案。包括尿道下裂和扁平苔藓硬化症患者在内的特殊患者群体是反复复发风险最高的人群,在手术技术、移植物选择和术后管理方面需要特别护理。
