经尿道钬激光与经尿道冷刀内切开治疗尿道狭窄的疗效比较

目的:比较经尿道钬激光与经尿道冷刀内切开治疗尿道狭窄的临床疗效。方法:25例尿道狭窄患者行经尿道钬激光切除,19例行经尿道冷刀内切开,分析两组患者手术时间、术后住院日、尿道狭窄复发率及再次手术率等指标,并比较临床疗效。结果:随访1~6年,两组术后住院日差异无统计学意义(P>0.05),但钬激光组尿道再次狭窄发生率及再次手术率均低于冷刀内切开组(P<0.05)。结论:钬激光治疗尿道狭窄疗效确切,并发症少,在减少再次狭窄发生率等方面比冷刀内切开更有优势。

Comparison between holmium laser resection and internal urethrotomy with cold knife for urethral stricture

Objective：To compare the clinical effects of holmium laser resection and internal urethrotomy with cold knife on urethral stricture.Methods：Twenty-five cases of urethral stricture were treated by holmium laser resection and 19 cases internal urethrotomy with cold knife.The mean operation time,postoperative hospital stay,recurrence of the stricture and re-operative rate were observed,and the clinical effects were compared between the two groups.Results：All the cases were followed up for 1 to 6 years.The postoperative hospital stay was not significantly different between the two groups（P〉0.05）.But the reoccurrence of the stricture and the re-operative rate were lowered in the holmium laser resection group compared with that in the internal urethrotomy with cold knife group（P〈0.05）.Conclusions：The holmium laser technique is effective for treatment of urethral stricture and leaves few complications.The holmium laser technique is superior to internal urethrotomy with cold knife in reduction of the incidence of recurrent stricture.
