Abstract］ objective to assess the efficacy and safety of holmium laser urethrotomy under ureteroscope to treat the urethral stricture.methods 16 cases were treated by holmium laser resection under ureteroscope.the length of the stricture was 0.1～1.0 cm.the blood loss and the complications as well as curative effect after operation were observed.results all of the cases were treated successfully with less bleeding and no severe complications.the maximal urinary flow rate improved obviously after operation.conclusion the holmium laser under ureteroscope demonstrates good effect to treat urethral stricture.

目的 探讨输尿管镜下钬激光切开术治疗尿道狭窄的疗效。方法 16例患者采用经尿道输尿管镜下钬激光切开术治疗，狭窄长度0.1～1.0 cm，观察其术中出血、术后并发症及疗效。结果 16例患者均顺利完成手术，疗效满意，术中出血少，术后最大尿流率较术前有明显改善，无严重并发症发生。结论输尿管镜下钬激光切开术治疗对尿道狭窄是一种安全、微创且行之有效的治疗方法。

The transparent transfer chamber measures 30.5Lx27.9dia.cm (12x11) and features an adjustable vacuum gauge.

For different surface roughness of electrodes and glycol concentration of glycol/water mixture, pressurized water breakdown experiments are carried out. Experimental results suggest that Mirza's formula is valid and independent of surface roughness and glycol concentration, and it is accumulative for surface polish, glycol additive, and pressurization for the capability to improve electrical breakdown strength. Moreover, the increase of electrical breakdown strength of water dielectric for surface polish is explained with bubble breakdown. Especially, highest stress of 235.5kV/cm observed in glycol/water mixture with a glycol concentration of 80% at a hydrostatic pressure of 12atm is about one time greater than that in pure water at constant pressure.

通过改变电极表面光滑程度和乙二醇浓度，分别进行了加压水介质击穿实验，证实了不同电极表面光滑程度和乙二醇浓度下Mirza关系式仍成立，抛光电极表面、添加乙二醇与加压在提高水介质电击穿能力方面具有可叠加性，将抛光电极表面、添加乙二醇与加压分别进行了比较，特别，在静压12atm、乙二醇浓度80%下，得到实测最高击穿场强为235.5kV/cm，其有效时间归一化后的击穿场强比常压下纯水的相应值提高了112.2%，运用气泡击穿模型对抛光提高水介质击穿场强进行了物理解释。
