To our knowledge this study of our first consecutive 1,000 patients treated with the Siemens Lithostar device is the largest prospective series reported to date. Treatment results were determined at 3, 12 and 24 months after completion of therapy. The results at 3 months are presented. Complete followup data were available on 801 patients: 674 with renal and 127 with ureteral calculi. Results were analyzed according to stone size, location and number. The average number of shocks per treatment was 3,804 and the retreatment rate was 18.6%. At 3 months the stone-free rate was determined by a plain film of the kidneys, ureters and bladder and plain tomograms for renal calculi, and by an excretory urogram for ureteral calculi. The stone-free rate was 52% for renal and 76% for ureteral calculi. The overall stone-free rate for all calculi was 55.7%. Success rate, defined as stone-free or asymptomatic residual fragments measuring 4 mm. or less, was 72% for renal and 83% for ureteral calculi. The overall success rate for all calculi was 73.9%.
据我们所知，这项对首批连续1000例使用西门子Lithostar设备治疗的患者的研究，是迄今为止报道的最大规模的前瞻性系列研究。治疗结果在治疗完成后的3个月、12个月和24个月时确定。本文呈现了3个月时的结果。801例患者有完整的随访数据：674例为肾结石患者，127例为输尿管结石患者。根据结石大小、位置和数量对结果进行分析。每次治疗的平均冲击波次数为3804次，再次治疗率为18.6%。3个月时，肾结石通过肾脏、输尿管和膀胱的平片以及肾结石的平扫断层扫描来确定结石清除率，输尿管结石则通过排泄性尿路造影来确定。肾结石的结石清除率为52%，输尿管结石为76%。所有结石的总体结石清除率为55.7%。成功率定义为结石清除或残留无症状碎片尺寸在4毫米及以下，肾结石的成功率为72%，输尿管结石为83%。所有结石的总体成功率为73.9%。
