Extracorporeal Shock Wave Lithotripsy (SWL) has long been used successfully to dissolve ureteral stones. We researched whether Hounsfield values of ureteral stones is a factor that affects the success of SWL.
Data from 144 patients who had diagnoses of ureteral stones and underwent SWL, were retrospectively reviewed between January 2011 and December 2012. Urinary tomography of patients was processed and classified into 3 groups by Hounsfield units (Group 1, < 500 HU; Group 2, 500-1000 HU; and Group 3, > 1000 HU) and 2 groups by stone size (Group A; < 1 cm, Group B; > 1 cm). SWL success was analyzed for both of these group types. Failure was defined as any fragments of the stone that remained within the ureter. Results were analyzed by evaluating the predictive factors in both groups.
The study included 144 patients (100 men, 44 women) who fit the inclusion criteria. In Hounsfield unit Group 1 (12 women and 44 men), the mean age was 37.2 ± 13.2, stone size was 8.5 ± 2.5 mm, number of shocks was 3240 ± 1414 (1200-7500) and number of treatments was 1.4 ± 0.6. In Group 2 (26 women and 32 men), the mean age was 33.6 ± 7.6, stone size was 9.6 ± 3.1 mm, process number was 3375 ± 2103 (1200-8750) and shock amount was 1.6 ± 0.8. In Group 3 (6 women and 24 men), the mean age was 42.2 ± 13.6, stone size was 11.7 ± 3.0 mm, number of shocks was 4513 ± 2458 (1300-8700) and number of treatments was 2.1 ± 1.2. In size Group 1 (28 women and 74 men), the mean age was 35.8 ± 10.6, stone size was 8.1 ± 1.4 mm, process number was 3105 ± 1604, shock amount was 1.4 ± 0.5 and HU value was 580 ± 297. In Group 2 (16 women and 26 men), the mean age was 39.9 ± 14.2, stone size was 13.9 ± 2.4 mm, number of shocks was 4722 ± 2467, number of treatments was 2.3 ± 1.1 and HU value was 912 ± 270.
Although stone density predicted the failure of SWL, size of the stone is more important criterion for successful lithotripsy of ureteral stones.
体外冲击波碎石术（SWL）长期以来一直成功用于溶解输尿管结石。我们研究了输尿管结石的亨氏值是否是影响SWL成功的一个因素。
回顾性分析2011年1月至2012年12月期间144例诊断为输尿管结石并接受SWL治疗的患者的数据。对患者的泌尿系统断层扫描进行处理，并根据亨氏单位分为3组（第1组，<500 HU；第2组，500 - 1000 HU；第3组，>1000 HU），根据结石大小分为2组（A组；<1 cm，B组；>1 cm）。对这两种分组类型的SWL成功率进行分析。失败定义为输尿管内残留任何结石碎片。通过评估两组中的预测因素来分析结果。
该研究纳入了144例符合纳入标准的患者（100例男性，44例女性）。在亨氏单位第1组（12例女性和44例男性）中，平均年龄为37.2±13.2岁，结石大小为8.5±2.5 mm，冲击次数为3240±1414（1200 - 7500），治疗次数为1.4±0.6次。在第2组（26例女性和32例男性）中，平均年龄为33.6±7.6岁，结石大小为9.6±3.1 mm，治疗次数为3375±2103（1200 - 8750），冲击次数为1.6±0.8次。在第3组（6例女性和24例男性）中，平均年龄为42.2±13.6岁，结石大小为11.7±3.0 mm，冲击次数为4513±2458（1300 - 8700），治疗次数为2.1±1.2次。在大小第1组（28例女性和74例男性）中，平均年龄为35.8±10.6岁，结石大小为8.1±1.4 mm，治疗次数为3105±1604，冲击次数为1.4±0.5次，亨氏值为580±297。在第2组（16例女性和26例男性）中，平均年龄为39.9±14.2岁，结石大小为13.9±2.4 mm，冲击次数为4722±2467，治疗次数为2.3±1.1次，亨氏值为912±270。
虽然结石密度可预测SWL失败，但结石大小是输尿管结石成功碎石更重要的标准。
