摘　　要：目的 探讨采用骑跨半坐位体位体外冲击波碎石术（SWL）治疗尿道结石的可行性、安全性和有效性.方法 1997年11月至2013年8月北京大学第一医院泌尿外科尿道结石患者7例,皆为男性,年龄24~52岁.前尿道结石1例,后尿道结石6例.结石大小：0.5 cm×0.5 cm至1.0 cm×2.0 cm.运用HB-VG复式脉冲低能量碎石机,采用骑跨半坐位体位行SWL治疗,每次治疗冲击波轰击次数为1 800~ 3 500次,平均2 500次,治疗电压：3~8 kV.结果 7例患者尿道结石均粉碎成功,SWL后1 h内结石均成功排空.SWL治疗后7例患者均出现血尿和排尿时尿道口轻微刺痛,均未出现严重并发症.结论 采用骑跨半坐位体位SWL治疗尿道结石是简单、安全、见效快的方法.Objective To explore the therapeutic feasibility, safety and efficacy of semi-sitting astride position for extracorporeal shock wave lithotripsy （SWL） of urethral calculi. Methods A total of 7 male cases of urethral calculi from November 1997 to August 2013 were enrolled. Their age range was 24 - 52 years. There were anterior （ n = 1 ） and posterior （ n = 6 ） urethral calculi. The diameter range of stone was 0. 5 cm× 0. 5 cm to 1.0 cm× 2. 0 cm. BH-VG twin-pulse low-energy SWL was employed with a semi-sitting astride position. The average frequency was 2 500 （ 1 800 - 3 500） times. And the treatment voltage was 3 - 8 kV. Results Both stone fragmentation rate and stone-free rate 1 hour post-SWL was 100%. No severe complications occurred. Conclusion Semi-sitting astride position SWL is simple, safe, effective and feasible for posterior urethral calculi.
