OBJECTIVES
The aim of this study was to assess the efficacy and safety of the neodymium:yttrium-aluminum-garnet (Nd:YAG) laser in the treatment of pediatric urethral stricture disease.
METHODS
Twelve boys who had previously undergone unsuccessful cold-knife internal urethrotomy or serial urethral dilation for urethral stricture disease underwent endoscopic laser internal urethrotomy utilizing a contact-tip fiber for recurrent urethral stricture.
RESULTS
At a mean follow-up of 12 months, 10 of the 12 boys are free of stricture disease for an overall success rate of 83%. Two boys were considered failures and underwent successful open urethroplasty. There were no treatment complications.
CONCLUSIONS
The Nd:YAG laser utilizing the contact-tip fiber was successful in treating recurrent urethral stricture disease. The hemostatic characteristic of the laser allowed bloodless urethrotomy, which was particularly useful when operating with the smaller pediatric endoscopic instruments.
目的
本研究旨在评估钕钇铝石榴石（Nd:YAG）激光治疗小儿尿道狭窄疾病的疗效和安全性。
方法
12名曾因尿道狭窄疾病接受冷刀内尿道切开术未成功或多次尿道扩张的男孩，接受了使用接触式光纤的内镜激光内尿道切开术治疗复发性尿道狭窄。
结果
平均随访12个月时，12名男孩中有10名无狭窄疾病，总成功率为83%。2名男孩被视为治疗失败，随后成功接受了开放性尿道成形术。无治疗并发症发生。
结论
使用接触式光纤的Nd:YAG激光成功治疗了复发性尿道狭窄疾病。激光的止血特性使尿道切开术无血，这在使用较小的小儿内镜器械操作时特别有用。
