目的:探讨筋膜扩张器在小儿尿道下裂术后尿道扩张中的临床运用。方法:回顾分析2005年以来治疗尿道下裂术后出现尿道狭窄15例患者临床资料,12例直接用斑马导丝引导后利用肾周筋膜扩张器进行尿道扩张成功,3例在输尿管镜直视下放置斑马导丝成功后再行扩张。结果:15例患者均成功完成尿道扩张,无假道形成,无严重尿路感染,术后排尿变细即刻缓解。结论:斑马导丝引导下用肾周筋膜扩张器进行小儿尿道扩张,方法简便、安全。
Objective: To investigate the clinical application of fascial dilator in urethral dilatation after pediatric hypospadias operation. Methods: The clinical data of 15 cases of urethral stricture after treatment of hypospadias were retrospectively analyzed. Twelve cases of urethral dilatation were successfully treated with perirenal fascial dilator guided by zebra guidewire. Three cases underwent ureteroscopy Under the placement of zebra guidewire after the success of expansion. Results: All the 15 patients successfully completed the urethral dilatation without the formation of a false urinary tract infection. The micturition was relieved immediately after operation. Conclusions: The method of perineal fascia dilator for the expansion of pediatric urethra guided by zebra guidewire is simple and safe.
