输尿管镜下气压弹道碎石术治疗输尿管结石的疗效分析

Efficacy Analysis of Ureteral Microscopically Pneumatic Ballistic Lithoclast in the Treatment of Ureteral Calculi

目的观察经输尿管镜气压弹道碎石术治疗输尿管结结石的疗效和并发症。方法随机选取牡丹江医学院第二附属医院泌尿外科自2007年10月至2010年10月收治的180例输尿管结石患者。根据治疗方法的不同,将180例患者分为两组,A组80例采用经输尿管镜超声碎石术,B组100例采用经输尿管镜气压弹道碎石。观察两组患者的单次手术操作成功率、结石排净率、平均住院时间及并发症发生率。结果 A组的首次结石排净率76.3%,尿路感染、输尿管狭窄、穿孔的发生率分别为12.5%、11.3%、12.5%,平均住院时间(6.0±2.3)d。B组的结石排净率89.0%,尿路感染、输尿管狭窄、穿孔的发生率分别为25.0%、3.0%、4.0%,平均住院时间(4.2±1.8)d,两组比较差异有统计学意义(P<0.05)。结论输尿管镜下气压弹道碎石术是高效、安全、易使用的方法。

Objective To observe the curative effect and complications of the ureteral mirror pneumatic ballistic lithoclast in the treatment of ureteral calculi.Methods To randomly selecte 180 patients since October 2007 October 2010 from urinary surgical of the second affiliated hospital of Mudanjiang medical School.According to the different treatment methods,180 were divided into two groups,A group of 80 patients with ureteral mirror by ultrasonic lithotripsy,B group of 100 patients with ureteral mirror by pneumatic ballistic gravel.To observe two groups in single operation success rate,the stone row net rate,the average hospitalization time and complications.Results The first stone row net rate of group A was 76.3%,the incidence of urinary tract infection,ureteral stricture,fenestration showed 12.5%,11.3%,12.5%respectively,the average hospitalization time was（6.0 ±2.3）d.The stone row net rate of group B was 89.0%,the incidence of urinary tract infection,ureteral stricture,fenestration showed 25.0%、3.0%、4.0% respectively,the average hospitalization time was（4.2 ±1.8）d,the difference of two groups was statistically significant（P0.05）.Conclusion The ureteral microscopically pneumatic ballistic lithoclast was efficient,safe,easy.
