Five patients with complete posterior urethral obliteration (less than 3 cm.) underwent endoscopic reconstitution of the urethra followed by planned direct vision internal urethrotomy and temporary self-dilation. Of these patients 3 complied with the treatment regimen and are currently free of voiding complaints (average followup 31 months), while 2 failed to perform self-dilation and required repeat internal urethrotomy. Of the latter 2 patients 1 then performed self-dilation and has a stable urethra (followup 2 years). The youngest patient refused to perform self-dilation and underwent successful perineal urethroplasty. Major complications did not occur. The treatment regimen as described is a suitable alternative to surgical urethroplasty in select patients with short urethral defects (less than 3 cm.) who are willing to perform temporary urethral self-dilation.
五名后尿道完全闭锁（长度小于3厘米）的患者接受了尿道内镜重建术，随后进行了计划性直视内尿道切开术和临时性自我扩张。这些患者中，3名遵循了治疗方案，目前没有排尿方面的主诉（平均随访31个月），而2名未进行自我扩张，需要再次进行内尿道切开术。在这2名患者中，有1名随后进行了自我扩张，尿道情况稳定（随访2年）。最年轻的患者拒绝进行自我扩张，接受了成功的会阴尿道成形术。未发生重大并发症。对于有短尿道缺损（小于3厘米）且愿意进行临时性尿道自我扩张的特定患者，所述治疗方案是手术尿道成形术的合适替代方案。
