目的：探讨用超脉冲等离子电极治疗尿道狭窄的方法和效果。方法：2005年2月～2006年8月，48例尿道狭窄患者，经尿道内窥镜下用超脉冲等离子电极进行瘢痕切割和汽化，对其疗效及技术要点进行分析。结果：全部病例均手术成功，术后47例获得3～18（平均10）个月随访，2例术后出现再狭窄，其中1例行定期尿道扩张术，另1例虽有排尿困难，暂未行治疗。结论：经尿道内窥镜直视下，用超脉冲等离子电极切割汽化瘢痕性尿道狭窄，手术操作精确，疗效满意。

英文摘要：

Objective： To evaluate the effect of internal urethrotomy with Super-impulse plasma electrode （SIPE） method on urethral stricture. Methods： A total of 48 patients clinically diagnosed as having urethral stricture were hospitalized and treated with SIPE under the endoscope from February 2005 to August 2006. The patients＇ symptoms and clinical signs were compared before and after the treatment. In addition, techniques in operating SIPE were discussed. Results： Of the 48 patients, 46 were cured and 2 experienced recurrence after the operation. A 3-18 months follow-up revealed no complications. Conclusion： SIPE under the endoscope is safe and effective in the treatment of urethrostenosis. It is easy to handle and the results are satisfactory.
