The management of an anastomotic stricture after a radical prostatectomy can become a complex and difficult situation when an artificial urinary sphincter precedes the formation of the stricture. The urethral narrowing does not allow the passage of the routinely used urological instruments and no previous reports have suggested alternate approaches.
We present the case of a 68-year-old Greek man diagnosed as having a recurrent anastomotic stricture approximately two years after a radical prostatectomy and three years after the implantation of an artificial urinary sphincter, and propose novel alternate methods of treatment. Our patient was first subjected to stricture incision with the use of a rigid ureteroscope with a holmium:yttrium-aluminium-garnet laser fiber, which was followed by a second successful attempt with the use of a pediatric resectoscope. After a one-year follow-up, our patient is doing well, with no evidence of recurrence.
To the best of our knowledge, this is the first report of the management of recurrent urethral strictures following an artificial urinary sphincter implantation. Minimal invasive techniques with the use of small caliber instruments may offer efficient treatment options, diminishing the danger of urethral corrosion.
当人工尿道括约肌在吻合口狭窄形成之前就已存在时,根治性前列腺切除术后吻合口狭窄的处理可能会变得复杂且困难。尿道狭窄使得常规使用的泌尿外科器械无法通过,且此前尚无报告提出替代方法。
我们报告一例68岁希腊男性患者,在根治性前列腺切除术后约两年、人工尿道括约肌植入术后三年被诊断为复发性吻合口狭窄,并提出了新的替代治疗方法。我们的患者首先使用带有钬:钇铝石榴石激光光纤的硬性输尿管镜进行狭窄切开,随后使用小儿电切镜再次成功治疗。经过一年的随访,我们的患者情况良好,无复发迹象。
据我们所知,这是人工尿道括约肌植入术后复发性尿道狭窄处理的首例报告。使用小口径器械的微创技术可能提供有效的治疗选择,降低尿道腐蚀的风险。
