[摘要] 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。

[Abstract] 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.

尿道狭窄是尿道损伤后最常见、影响最为严重的并发症,而尿道扩张术是治疗尿道狭窄的主要方法之一[1]。而尿道扩张多数在门诊进行,由于多种原因常有扩张失败。为了提高疗效我们于1998年5月~2007年10月采用改良金属导尿管导引尿道扩张治疗尿道狭窄,疗效较好,现报道如下。
