输尿管结石的IVU与CT的检测对比

Compare Volue of IVU and CTfor Kidney Stone

目的比较16层螺旋CT低剂量平扫与IVU对肾及输尿管结石的价值。方法收集我院2003年1月-2009年1月68例临床拟诊肾及输尿管结石病例，所有病例作16层螺旋CT低剂量平扫和IVU，比较两者检测肾及输尿管结石的病例数、数目及输尿管梗阻情况．两组结果进行统计学分析。结果在16层螺旋CT低剂量平扫中，68例发现结石，肾结石47例，输尿管结石36例．结石数量为93个；在IVU检查中，49例发现结石，肾结石32例，输尿管结石27例，结石数量为69个。经统计学分析，两者在发现结石病例数、结石数量上均有显著性差异。结论16层螺旋CT低剂量平扫技术为诊断输尿管结石快捷、安全、精确的方法，优于IVU。

Objective compare value of plain scan of 16 layers of spiral CT low dosage on the kidney and on the ureter stone. Method collect 68 cases of clinically examined kidney and ureter stone cases from January 2003- January 2009 of our hospital. Perform 16 layers of spiral CT plain low dosage scan and IVU for all cases and compare case load, quantity and ureteral obstruction condition of the kidney and ureter stone detected by the two methods. Perform statistic analysis to the two groups of results. Result during plain scan performed with 16 layers Of spiral CT low dosage, concretions are found in 68 cases, kidney stone are found in 47 cases, ureter stone are found in 36 cases with 93 concretions; during IVU inspection, concretions are found in 49 cases, kidney stone are found in 32 cases, ureter stone are found in 27 cases with 69 concretions; there is significant difference in the concretion case load and concretion quantity discovered by the two methods through statistic analysis. Conclusion plain scan technology of 16 layers of spiral CT low dosage is the rapid, safe and precise method for diagnosing the ureter stone. It exceeds IVU.
