目的:探讨肾筋膜扩张器治疗男性尿道狭窄的疗效及安全性。方法:对31例男性尿道狭窄患者实施肾筋膜扩张器扩张治疗。输尿管硬镜直视下尿道置入导丝,C型臂X线透视证实导丝进入膀胱,X线监视下肾筋膜扩张器沿导丝依次扩张狭窄处,扩张成功后尿道留置硅胶导尿管。术后门诊随访,定期扩张尿道。结果:28例尿道狭窄患者单纯行肾筋膜扩张器扩张成功,3例狭窄长度>1 cm者单纯肾筋膜扩张器扩张困难,钬激光行狭窄处内切开后,肾筋膜扩张器依次扩张。随访4~32个月,29例排尿通畅,2例因未坚持术后定期扩张再次出现尿道狭窄,行二次手术治疗。31例无尿道穿孔、撕裂及假道形成等并发症出现。结论:单纯使用肾筋膜扩张器治疗狭窄长度小于1 cm的男性尿道狭窄疗效可靠、安全性高。
Objective: To investigate the efficacy and safety of renal fascia dilator in treatment of male urethral stricture. Methods: Thirty-one male patients with urethral stricture were treated with dilated renal fascia dilator. Ureteroscopic direct urethral implantation of guide wire, C-arm X-ray confirmed the guide wire into the bladder, X-ray monitoring under the fascia dilatation of the stent along the guide wire followed by stenosis, expansion of the urethral indwelling silicone catheter . Follow-up postoperative clinic, regular expansion of the urethra. Results: In 28 cases of urethral stricture, the expansion of renal fascia dilator was successful. In 3 cases, the simple renal fascia dilator was difficult to expand in 3 cases with stenosis> 1 cm. After holmium laser incision in the stenosis, expansion. Followed up for 4 to 32 months, 29 cases of urinary tract patency, 2 cases of urethral stricture again did not adhere to regular postoperative expansion, the line of second surgery. 31 cases of no perforation of the urethra, tearing and false pathology and other complications appear. Conclusion: The simple use of renal fascia dilator for stenosis of less than 1 cm in male urethral stricture effective and safe.
