直出光源绿激光手术系统在尿道狭窄治疗中的临床应用

Evaluation of End fire greenlight high performance system laser in the treatment of urethral stricture

目的:探讨直出光源绿激光手术系统在尿道狭窄治疗中的安全有效性。方法:对25例尿道狭窄的患者应用直出绿激光光纤行经尿道尿道狭窄内切开及瘢痕汽化切除术进行回顾分析。对手术时间、术后留置导尿时间、并发症、最大尿流率、剩余尿等指标进行评价。结果:25例均顺利完成手术,手术时间10~30min,平均(21.44±6.07)min;术中出血量为:5~10ml。住院时间为5~7d。术后拔管后最大尿流率由(5.82±2.45)提高到(16.84±4.23)ml/s,剩余尿由(350.54±42.76)ml降至(24.54±8.72)ml,手术前后均差异有统计学意义(P<0.01)。结论:直出光源绿激光手术治疗系统治疗尿道狭窄具有微创、出血少,术后恢复快、并发症少、复发少的特点,是尿道狭窄治疗手术方式的一个较好选择。

Objective:To evaluate the safety and efficacy of End fire greenlight high performance system(HPS)laser in the treatment of urethral stricture.Methods:Twenty-five cases underwent endoscopic urethrotomy and scar vaporization by End fire greenlight laser HPS.The clinical data of all the 25 patients were collected and analyzed,including operational time,operative bleeding volume,time of indwelling catheter after operation,complications after operation,urine flow rate(Qmax)and residual urine(RUV).Results:All operations were performed successfully.The average time of operation and operative bleeding volume was(21.44±6.07)min and(5-10)mL,respectively.Qmaxwas greatly improved from(5.82±2.45)mL/s to(16.84±4.23)mL/s after catheter removal,and RUV was greatly reduced from(350.54±42.76)mL to(24.54±8.72)mL/s(P<0.01).Conclusions:End fire greenlight laser HPS is a good choice in the treatment of urethral stricture because of the minimal invasion,little bleeding and complications,quick recovery and low recurrence.
