目的观察经尿道RevoLix 2μm激光分层递进切开术治疗复杂性尿道狭窄的疗效。方法对确诊的26例复杂性尿道狭窄患者行经尿道2μm激光分层递进切开术,观察临床效果及并发症发生情况。结果本组手术均获成功。手术时间20~80 min,平均45 min。术后随访4~24个月,平均12个月,22例(84.62%)治愈,最大尿流率15.5~30.8 mL/s,平均(22.8±4.8)mL/s;3例(11.54%)好转;1例(3.85%)失败者改行尿道拖入术治愈。结论经尿道腔内RevoLix 2μm激光分层递进切开术治疗复杂性尿道狭窄疗效满意,且创伤小、愈合快、并发症少、复发率低。 Objective To observe the curative effect of transurethral RevoLix 2μm laser layered progressive incision in the treatment of complicated urethral stricture. Methods Twenty-six patients with complicated urethral stricture underwent progressive laser incision by 2μm laser in the urethra. The clinical effects and complications were observed. Results The surgery was successful. Surgery time 20 ~ 80 min, an average of 45 min. The patients were followed up for 4 to 24 months with an average of 12 months. Twenty-two patients (84.62%) were cured. The maximum flow rate was 15.5-30.8 mL / s, with an average of (22.8 ± 4.8) mL / s. ; 1 case (3.85%) losers were diverted to urethral drag surgery. Conclusion RevoLix 2μm laser-guided intra-urethral progressive incision is a satisfactory and effective method to treat complicated urethral stricture with less trauma, faster healing, less complications and low recurrence rate.
