改良金属导尿导管引导尿道扩张治疗尿道狭窄

Treatment of Urethral Stricture by Guiding and Dilating Urethra with Improved Metallic Catheter

目的评价改良金属导尿管用于尿道狭窄的治疗效果。方法采用改良金属导尿法,将金属导尿管进行改进,把金属导尿管圆头用电钻开孔,使之能通过F5输尿管导管,增加尿道扩张的方向感,达到顺利扩张之目的。结果共30例患者,28例病人经此法扩张后治愈,2例患者经全程治疗后仍有排尿不畅现象,后给予内镜直视下尿道内冷刀切开术加改良尿道扩张术治疗。30例患者全部治愈。随访6个月～1年,均排尿通畅。结论对尿道狭窄,改良金属导尿管导引尿道扩张治疗效果满意。

Objective To evaluate the treatment effect of metallic catheter on urethral stricture. Methods In our study, the metallic catheter was improved,and a pore was drilled on the trochocephalias of the catheters to pass a ureteral catheter so that the direction-sense could be enhanced. Results Thirty cases were included, 28 of them were cured by this method, and 2 cases still had the symptom of urethral stricture but cured after internal urethrotomy and regular dilation again. The follow-up from 6 months to 12 months showed normal urination was achieved in all cases. Conclusion The improved metallic catheter has a good treatment effect on urethral stricture.
