Some reports have shown a decreased effectiveness of extracorporeal shock wave lithotripsy (ESWL*) with newer lithotriptors. We used a first generation unmodified Dornier HM3 lithotriptor to treat 5,698 patients with renal and ureteral calculi and a second generation Medstone STS device to treat 8,166 patients with renal and ureteral calculi. The treatment results were compared using the chi-square test to determine statistical significance. The stone-free rate, retreatment rate and post-ESWL secondary procedure rate were 69.5%, 4.4% and 3.1%, respectively, with the Dornier HM3 device and 72.1%, 4.9% and 2.3%, respectively, with the Medstone lithotriptor for single renal stones, and 81.5%, 5.2% and 5.5%, respectively, with the Dornier HM3 and 83.2%, 5.2% and 5.0%, respectively, with the Medstone device for single ureteral stones. There were no statistically significant different results between a second generation tubless Medstone STS lithotriptor and the gold standard unmodified Dornier HM3 instrument.
一些报告显示,使用新型碎石机时,体外冲击波碎石术(ESWL*)的有效性有所下降。我们使用第一代未改良的多尼尔HM3碎石机治疗了5698例肾和输尿管结石患者,并使用第二代Medstone STS设备治疗了8166例肾和输尿管结石患者。使用卡方检验比较治疗结果以确定统计学意义。对于单个肾结石,使用多尼尔HM3设备时的结石清除率、再次治疗率和ESWL后二次手术率分别为69.5%、4.4%和3.1%,使用Medstone碎石机时分别为72.1%、4.9%和2.3%;对于单个输尿管结石,使用多尼尔HM3时分别为81.5%、5.2%和5.5%,使用Medstone设备时分别为83.2%、5.2%和5.0%。第二代无管Medstone STS碎石机与金标准未改良的多尼尔HM3仪器之间的结果在统计学上无显著差异。
