Urethral stricture presents an uncommon but difficult urological problem in the pediatric population. Treatment protocols are different from in adults due to anatomical considerations.
A thorough manual and Medline search was conducted to review the existing literature on post-traumatic pediatric urethral strictures, with key words: stricture, children, post-traumatic, urethroplasty, pediatric.
Opinion early on was that, due to the confined perineum, high incidence of supramembranous injury resulting in less predictable distraction defects of the posterior urethra and a high incidence of prostatic displacement, transperineal urethroplasty is technically more difficult than in adults and thus the transpubic approach is more feasible. Recent reports revealed that both approaches resulted in almost the same clinical outcomes for children with post-traumatic posterior urethral strictures.
The ideal reconstruction for the treatment of post-traumatic posterior urethral strictures in children is bulboprostatic anastomosis. This procedure should be initially attempted through the perineum in every case. A transpubic procedure should be done only when tension-free anastomosis cannot be accomplished through the perineum.
尿道狭窄在儿科人群中是一种不常见但较为棘手的泌尿科问题。由于解剖学上的考虑,其治疗方案与成人不同。
我们进行了全面的手动和 Medline 检索,以回顾关于创伤后小儿尿道狭窄的现有文献,关键词为:狭窄、儿童、创伤后、尿道成形术、儿科。
早期的观点认为,由于会阴部受限,膜上损伤发生率较高,导致后尿道的可预测性分离缺陷,且前列腺移位发生率较高,经会阴尿道成形术在技术上比成人更困难,因此耻骨后入路更为可行。最近的报告显示,对于创伤后后尿道狭窄的儿童,两种方法的临床结果几乎相同。
对于儿童创伤后后尿道狭窄的治疗,理想的重建方法是球部前列腺吻合术。在每种情况下,都应首先尝试通过会阴进行此操作。只有当无法通过会阴完成无张力吻合时,才应进行耻骨后入路。
