摘要
目的：探讨应用输尿管镜联合筋膜扩张器进行尿道扩张治疗男性尿道狭窄的临床疗效。方法：18例尿道狭窄患者在输尿管镜直视下置入斑马导丝通过狭窄处进入膀胱,沿留置的斑马导丝逐号置入筋膜扩张器扩张尿道,儿童患者可根据年龄用筋膜扩张器扩张至适当型号即可;而成人用筋膜扩张器扩张至F18号后,可根据需要再用F20号以上的金属扩张器进行扩张。然后留置合适型号的导尿管1周至1个月,随访6-24个月。结果：18例患者均一次扩张成功,无尿道穿孔、撕裂及假道形成等并发症。其中16例经定期尿道扩张治愈,其余2例因尿道狭窄复发而转为开放手术治疗。术后最大尿流率（Qmax）为13.6-30.2（18.1±3.5）ml/s。结论：输尿管镜直视和斑马导丝引导下用筋膜扩张器进行尿道扩张方法简单,安全有效,是治疗男性尿道狭窄的一个较好的选择。
Objective：To explore the efficacy of urethral dilatation with the renal sheath dilator under the ureteroscope in the treatment of male patients with urethrostenosis.Methods：Eighteen male patients with urethrostenosis underwent urethral dilatation with the renal sheath dilator.Under the ureteroscope,a zebra-guide wire was inserted through the stenosed urethra into the bladder and the stenosis was gradually dilated with the renal sheath dilator,followed by placing a Foley catheter of proper size for 1-4 weeks.For children,the renal sheath dilator was selected according to their age,while for adults,metal dilators（≥ F20） were used following dilatation with the F18 renal sheath dilator.All the patients were followed up for 6-24 months.Results：The operation was successfully performed in all the 18 cases,with no urethral false passage,urethral perforation or urethra tearing.Sixteen of the patients were cured,and the other 2 received urethroplasty for stenosis recurrence.The maximum flow rate was increased to 13.6-30.2（18.1 ± 3.5） mL/s after the operation.Conclusion：Urethral dilatation with the renal sheath dilator under the ureteroscope is a simple,safe and effective method for the treatment of urethrostenosis.
