目的:探讨采用斑马导丝引导下筋膜扩张器治疗尿道下裂术后尿道狭窄的临床疗效。方法:2005年4月～2011年10月采用斑马导丝引导下筋膜扩张器治疗尿道下裂术后尿道狭窄患者18例。结果:15例采用该法成功施行尿道扩张,历经2～6次不等,扩张后均未发生尿路感染、附睾炎、尿道大量出血、尿道穿破或假道形成等严重并发症;3例尿道瘢痕狭窄严重或尿道成角而未能置入斑马导丝,择期改行尿道成形术。15例获得4～18个月随访,均排尿通畅,尿线粗而有力;6例术后2～6个月行尿流率检查,最大尿流率均大于20ml/s。结论:采用斑马导丝引导下筋膜扩张器治疗尿道下裂术后尿道狭窄操作简单,安全性高,临床应用疗效良好,值得推广。
Objective: To investigate the clinical efficacy of zebra guidewire-guided fascia dilator in the treatment of urethral stricture after hypospadias operation. Methods: From April 2005 to October 2011, 18 cases of urethral stricture treated by hypospadias guided fascia dilator. Results: In 15 cases, urethral dilatation was successfully performed after 2 to 6 times. No serious complications such as urinary tract infection, epididymitis, massive urethral bleeding, urethral perforation or false passage were found in 3 cases Urethral stricture or urethral stricture of the urethra and can not be placed into the zebra guide wire, elective urethroplasty. Fifteen patients were followed up for 4 to 18 months. All patients had smooth voiding and thick urinary tract. Six patients underwent urinary flow test at 2-6 months after operation, and the maximum uroflow rate was higher than 20ml / s. Conclusion: The zebra guidewire-guided fascia dilator for the treatment of urethral stricture urethral stricture is simple, safe, good clinical application, it is worth promoting.
