In 282 patients 290 ureteral stones were treated with extracorporeal shock wave lithotripsy using the Lithostar lithotriptor. Stones were in the upper ureter in 198 units (68.3%), middle ureter in 36 (12.4%) and lower ureter in 56 (19.3%). The average stone mass was 11.9 mm. and the mean number of shock waves was 4,913 for all levels with a mean kv. of 16.9. The average number of sessions was 1.5 for all sites. Auxiliary measures in the form of ureteral catheterization were done in 24 patients (8.5%) and internal stenting in 12 (4.25%), all of whom had upper or middle ureteral stones. Disintegration of the stones was achieved in 99% of the upper, 93.7% of the middle and 91.7% of the lower ureteral stones. However, clearance of fragments within 3 months from the last session was achieved in 94.8% of the upper, 87.5% of the middle and 91.7% of the lower ureteral stones for an overall stone-free rate of 93.3%.
对282例患者的290颗输尿管结石使用Lithostar碎石机进行体外冲击波碎石治疗。结石位于上段输尿管198颗（68.3%），中段输尿管36颗（12.4%），下段输尿管56颗（19.3%）。结石平均大小为11.9毫米。所有部位冲击波平均次数为4913次，平均千伏值为16.9。所有部位平均治疗次数为1.5次。24例患者（8.5%）采用输尿管插管形式的辅助措施，12例患者（4.25%）采用内支架置入，所有这些患者均患有上段或中段输尿管结石。上段输尿管结石99%、中段输尿管结石93.7%、下段输尿管结石91.7%实现结石碎裂。然而，在上段输尿管结石中，94.8%、中段输尿管结石中87.5%、下段输尿管结石中91.7%在最后一次治疗后3个月内实现碎片清除，总体无石率为93.3%。
