摘　　要：目的研究泌尿系结石CT值和结石成分间的关系及评价体外冲击波碎石(ESWL)临床应用价值。方法收集117例经ESWL治疗的泌尿系结石患者,治疗前行CT扫描测定结石CT值,对治疗后碎石进行成分分析,统计各种结石的对应CT值范围;根据碎石结果分排空组及残余组,统计学分析两组间结石CT值与排空率差异。结果本组结石平均CT值在323～1 580 Hu之间。结石CT值≤900 Hu 85例,结石CT值>900 Hu 32例。本组纯结石33例(28.21%),混合性结石84例(71.79%),混合结石的CT值均在相应两种成分纯结石的CT值之间,结石清除组81例(69.23%),结石残余组36例(30.77%),结石CT值及碎石冲击次数差异具有高度统计学意义(P<0.01)。结论平扫结石CT值能预测尿结石的主要成分,可作为评估ESWL治疗效果参考指标之一。Objective To research the relationship between the CT value and compositions of the urinary calculi and evaluate the clinical application value of the ESWL. Methods A total of 117 patients diagnosed with urinary calculi who were treated by ESWL during 2008-2010 in our institute were investigated. The CT values of the calculi were measured preoperatively and the compositions of the small particles were analyzed to conclude each CT value range with sorts of calculi respectively. According to the treatment outcomes, the emptying group and the residual group were builded and the different of the CT value between the two groups was analysed statistically. Results The average CT value of the calculi ranged from 323 Hu to 1 580 Hu. 85 cases is equal or below 900 Hu and 32 cases above 900Hu. 33 cases with single-ingredient（28.21%） compared with 84 cases multi-ingredient （71.79%） whose CT value ranged between the values of the two different single-ingredient groups. The emptying group consists of 81 cases and the residual group 36 cases. The different of the CT value and treatment times show statistical significant （P 〈 0.01 ）. Conclusion The CT value of urinary calculi scanning may be used as one of the reference indicators for the ESWL treatment evaluation with its effect in prediction of the Calculi compositions
