Abstract: 【Abstract】〓Objective〓To study the efficacy of optical internal urethrotomy with Holmium laser and balloon dilation in the treatment of urethral stricture. Methods〓From June 2013 to December 2014,.a total of 36 patients with symptomatic urethral stricture were evaluated with clinical history, physical examination,.uroflowmetry,.and retrograde urethrogram preoperatively..All patients were treated with optical internal urethrotomy followed by balloon dilation at the urethrotomy site..An indwelling 16-18Fr silicone catheter was left in place for a period of 7-21 days..All patients were followed up for 6-12 months postoperatively with symptoms, uroflowmetry, and retrograde urethrogram and micturating urethrogram every 3 months if indicated. Results〓The overall success rate after first OIU(optical internal urethorotomy) (30 out of 36 patients) was 83.4%. Urethral restenosis occurred in 6 cases. Conclusion〓Optical internal urethorotomy by Holmium laser with balloon dilation is a safe and effective minimally invasive therapeutic modality for urethral strictures.

摘要： 【摘要】 目的 研究直视下钬激光尿道内切开并球囊扩张治疗尿道狭窄的疗效。方法〓2013年6月至2014年12月,共收治36例尿道狭窄患者,术前详询病史、体检、行尿流率测定及逆行尿道造影,所有病人在尿道狭窄处行直视下钬激光尿道内切开和球囊扩张,术后留置16~18Fr硅胶尿管7~21天,所有病人术后随访6~12个月,随访期间测定尿流率,必要时每3个月进行尿道逆行造影或排泄性尿路造影。结果〓第一次术后治愈30例,总体成功率为83.4%。6例再狭窄和狭窄并尿瘘。结论〓直视下钬激光尿道内切开联合球囊扩张是治疗尿道狭窄安全有效的微创方法。
