目的介绍在X线透视下经导丝引导筋膜扩张器进行尿道扩张治疗男性尿道狭窄的方法及疗效。方法 16例尿道狭窄患者在X线监视下行尿道造影后,将血管介入使用的超滑泥鳅导丝通过狭窄处进入膀胱,沿留置导丝置入适当大小的筋膜扩张器扩张尿道,扩张后留置合适型号的导尿管1周,随访6～24个月。结果 16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。随访13例经定期尿道扩张治愈,失访3例。术后经尿道造影证实尿道狭窄残余<10%,患者排尿通畅。结论在X线透视下经导丝引导筋膜扩张器进行尿道扩张简单、安全,是治疗男性尿道狭窄的一个较好的方法。
Objective To introduce the method and efficacy of transurethral fascia dilator for urethral stricture in male under ureteral fluoroscopy. Methods Sixteen cases of urethral stricture underwent urethroprography under X-ray monitoring. The urethral loach loach guide wire used for vascular intervention was inserted into the bladder through the stenosis and placed into the bladder along the indwelling guide wire with the appropriate size of fascia dilator to expand the urethra. The appropriate type of catheter for 1 week, followed up for 6 to 24 months. Results All the 16 patients were successfully dilated. No complications such as urethral perforation, laceration and false passage formation were found. Follow-up of 13 cases cured by regular urethral dilatation, lost 3 cases. Postoperative transurethral angiography confirmed urethral stricture residual <10%, patients with voiding patency. Conclusions It is a simple and safe method to guide the urethral dilatation through the guidewire fascia dilator under X-ray. It is a better method to treat male urethral stricture.
