摘要
目的 总结不同CT值对应的结石成分,对结石成分初步估计;评价不同CT值的上尿路结石行体外冲击波碎石（ESWL）的疗效.方法 建立筛选条件收集在本院行体外冲击波碎石治疗的患者169例,治疗前行结石CT平扫检查,治疗后收集碎石测定结石成分并记录治疗方式、过程和结果.结果 一水草酸钙结石（716±191 Hu）、磷酸钙结石（1197±221Hu）、尿酸结石（372±49 Hu）、磷酸钙＋一水草酸钙结石（981±283 Hu）、尿酸＋磷酸钙结石（556±299 Hu）之间CT值的差异有统计学意义（P＜0.05）;结石获得1次碎石排空、2次碎石排空和2次碎石不能排空对应的CT值范围分别为（537±71）Hu、（833±80） Hu和（989±96） Hu,三组间比较差异有统计学意义（F=44.679,P=0.000）.结论 治疗前CT平扫可以初步预测结石的成分,并对治疗方法的选择提供参考.
Objectives To summarize different CT value and the corresponding calculus composition,then make an intial estimate to calculus composition ; evaluate the curative effect of ESWL in different CT value.Methods Establish screening condition and collected 290 patients who received ESWL in our hospital,examine CT plain scan before treatment and collect stone fragment determine the composition.Record the therapy method,process and result.Results Among calcium oxalate monohydrate calculus（716 ± 191 Hu）,Calcium phosphate calculus（1197 ± 221 Hu）,uric acid calculus（372 ± 49 Hu）,calcium phosphate and calcium oxalate monohydrate calculus（981 ±283 Hu）,uric acid and calcium phosphate calculus（556 ±299Hu）.their CT values of the difference has statistical significance（P ＜ 0.05） ;There was a statistically significant diference among once-teatment group,twice-teatment group and twice-teatment still useless group （F =44.679,P =0.000）.Conclusions Examine CT plain scan before treatment can initial estimate the calculus composition and to direct the chose of treatment method.
