为观察半导体激光治疗后尿道狭窄的效果，１９９５年１０月～１９９７年３月，应用ＤＩＯＭＥＤ半导体激光器治疗后尿道狭窄１６例，１３例获得手术一次成功，其余３例首次手术无改善，是尿道内瓣膜所致。结果表明，此种激光治疗后尿道狭窄成功率高，但尿道内残余瓣膜是手术失败的主要原因。半导体激光器较之其他类型激光器有功率大、汽化效果好、操作简单等优点。 To observe the effect of urethral stricture after semiconductor laser treatment, from October 1995 to March 1997, 16 cases of posterior urethral stricture were treated with DIOMED semiconductor laser, 13 cases were successful in one operation and the other 3 cases did not improve in the first operation. Valvular caused. The results show that the success rate of urethral stricture after laser treatment is high, but the residual valve in the urethra is the main reason of failure. Compared with other types of semiconductor lasers have high power, vaporization effect, simple operation and so on.
