目的:探讨顺行置入导丝引导筋膜扩张器行尿道扩张术治疗尿道下裂术后复杂性尿道狭窄的临床疗效。方法:对其他尿道扩张方法治疗失败的尿道下裂术后复杂性尿道狭窄12例,经耻骨上膀胱造瘘孔放入输尿管镜,经输尿管镜将斑马导丝置入尿道,顺斑马导丝逐号置入筋膜扩张器进行尿道扩张。术后放置硅胶气囊尿管2周。结果:12例均获成功,拔尿管后排尿通畅,随访6~28个月,其中8例定期常规方法尿道扩张1~6次后治愈,另4例不再出现排尿困难。结论:顺行置入导丝引导筋膜扩张器行尿道扩张术是治疗尿道下裂术后复杂性尿道狭窄安全有效方法。
Objective: To investigate the clinical curative effect of urethral dilation guided by fascia dilator inserted into guidewire to treat complex urethral stricture after hypospadias operation. Methods: Twelve cases of complicated urethral stricture after failed urethral dilatation were treated by urethral dilatation. Ureteroscope was placed in the ureteroscope through the puborectalis fistula. Ureteroscope was used to place the zebra guide wire into the urethra. No. into fascia dilator urethral dilatation. Silicone balloon catheter was placed for 2 weeks after operation. Results: All the 12 cases were successful. After extubation, the urination was smooth and the follow-up was 6-28 months. Eight of them were cured after routine urethral dilation 1-6 times, and the other 4 cases no longer had dysuria. CONCLUSION: The urethral dilatation guided by guide wire and fascia dilator directly is a safe and effective method for the treatment of complicated urethral stricture after hypospadias operation.
