摘要
目的:探讨双定位体外冲击波碎石机治疗泌尿系结石的临床疗效。方法:用X线和B超双定位体外冲击波碎石机治疗上尿路结石患者300例(实验组),并与同期用B超定位的体外冲击波碎石机治疗的上尿路结石患者300例(对照组)的疗效进行比较。结果:实验组手术时间、结石排净时间均显著短于对照组(P<0.05),输尿管上段、中下段结石定位成功率(分别为99%、98%)均明显高于对照组(分别为74%、68%),差异有统计学意义(χ2分别为4.35、6.32,P均<0.05),实验组在输尿管上段、中下段结石一次性碎石成功率(分别为92%、90%)均明显高于对照组(分别为65%、63%),差异有统计学意义(χ2分别为6.25、6.16,P均<0.05)。实验组术后感染3例,出现"石街"2例,对照组术后感染4例,出现"石街"3例,两组并发症发生率比较差异无统计学意义(P>0.05)。结论:X线和B超双定位系统体外冲击波碎石机在协助定位上取长补短,提高定位成功率和碎石成功率,缩短了手术时间,促进了患者康复。
Objective： To explore the effect of double positioning extracorporeal shock wave lithotripsy on urinary calculi patients.Methods：A total of 300 patients with upper urinary tract calculi were treated by double orientation extracorporeal shock wave lithotripsy（experimental group）,and another 300 upper urinary tract calculi patients were treated by B ultrasound localization extracorporeal shock wave lithotripsy at same period（control group）.The therapeutical effect was compared between two group patients.Results：The operation time,lithagogue time of experimental group was significantly shorter than control group（P 0.05）.The success rates of upper ureter,middle-lower ureteral calculi positioning in the experimental group were significantly higher than control group（χ2 = 4.35,χ2 = 6.32,P0.05）.The success rates of lithotripsy in the upper ureter,middle-lower ureteral were significantly higher in experimental group than control group（χ2 = 6.25,χ2 = 6.16,P0.05）.There were 3 cases with infection after surgery in experiment group,including 2 cases with steinstrasse,and 4 cases with infection in control group,including 3 cases with steinstrasse.But there was no significant difference in complication rate between two groups（P0.05）.Conclusions： Double positioning system extracorporeal shock wave lithotripsy machine with X and B ultrasound assisted positioning can improve the success rate of positioning and the success rate of lithotripsy,shorten the operation time,and promote the rehabilitation of patients.
