The treatment results obtained in children using an unmodified Dornier HM3 or a Medstone STS lithotripter for renal and ureteral stones were compared. The Dornier HM3 was used to treat 28 renal and 10 ureteral stones, while the Medstone STS was used to treat 73 renal and 34 ureteral stones. The treatment results were compared using the chi-square test to determine statistical significance. The stone-free rate, retreatment rate, and post-SWL secondary-procedure rate were 68%, 4%, and 0, respectively, with the Dornier HM3 and 93%, 6%, and 3.6%, respectively, with the Medstone STS for single renal stones and 80%, 0, and 0, respectively, with the Dornier HM3 and 82%, 0, and 5.9%, respectively, with the Medstone STS for single ureteral stones. Abnormal anatomy (horseshoe kidney, allograft kidney) or functional interference with the passage of fragments (urinary diversion, neurogenic bladder) was present in 16% of the children treated with the Dornier HM3 compared with 5% of those treated with the Medstone STS (p = 0.36). The treatment results with the unmodified Dornier HM3 and the Medstone STS were similar except for the statistically significantly higher stone-free rate for single renal stones obtained with the Medstone STS. The difference was most likely attributable to the smaller number of children with abnormal anatomy or functional interference with the passage of fragments who were treated with the Medstone.
比较了使用未改良的多尼尔HM3或Medstone STS碎石机治疗儿童肾和输尿管结石的治疗结果。多尼尔HM3用于治疗28例肾结石和10例输尿管结石，而Medstone STS用于治疗73例肾结石和34例输尿管结石。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时的无石率、再次治疗率和体外冲击波碎石术后二次手术率分别为68%、4%和0，使用Medstone STS时分别为93%、6%和3.6%；对于单个输尿管结石，使用多尼尔HM3时分别为80%、0和0，使用Medstone STS时分别为82%、0和5.9%。接受多尼尔HM3治疗的儿童中有16%存在解剖异常（马蹄肾、同种异体肾）或对碎片通过的功能干扰（尿流改道、神经源性膀胱），而接受Medstone STS治疗的儿童中这一比例为5%（p = 0.36）。除了Medstone STS治疗单个肾结石的无石率在统计学上显著更高外，未改良的多尼尔HM3和Medstone STS的治疗结果相似。这种差异很可能归因于接受Medstone治疗的存在解剖异常或对碎片通过有功能干扰的儿童数量较少。
