摘　　要：目的:通过与普通泌尿系平片(KUB)的对照,探讨数字化体层融合技术(DTS)在泌尿系结石诊断中的价值。方法:对73例临床疑诊泌尿系结石患者,均行KUB摄片和DTS成像,检查结果经手术证实。对KUB与DTS成像诊断泌尿系结石的敏感度、特异度进行比较并做统计学分析。结果:61例疑诊患者被证实为泌尿系结石,余12例正常。KUB确诊32例,DTS成像确诊55例。KUB、DTS成像诊断敏感度分别为52.5.0%(32/61)、90.2%(55/61),特异度分别为66.7%(8/12)、83.3%(10/12)。统计学分析显示,KUB、DTS成像术前诊断泌尿系结石与手术金标准比较,两种检查方法的诊断符合率差异有统计学意义(χ2=21.195,P值=0.001)。结论:DTS成像技术可显著提高泌尿系结石的定性诊断符合率,可作为诊断该病的常规影像检查方法。To contrastively evaluate the clinical application value of X-ray digital synthesis （DTS）with conventional plain radiography of kidney,ureter and bladder （KUB）in the diagnosis of urinary calculi.Methods：73 patients with suspected urinary calculi who underwent both KUB and DTS exams were studied.All diagnoses were verified by oper-ations.Chi-squared test was applied to evaluate the difference of sensitivity and specificity between the two methods. Results：61 cases were proved to have urinary calculi,while other 12 cases were normal.Among those who were proved by operations,32 cases were diagnosed by KUB,55 cases by DTS.The diagnostic sensitivity and specificity of KUB and DTS were 52.5% （32/61）,90.2% （55/61）,66.7% （8/12）and 83.3 （10/12）,respectively.There was significant difference be-tween KUB and DTS （χ2 =21.195,P=0.001）.Conclusion：DTS is a better method than KUB in diagnosing urinary calculi and can be used as a routine imaging technique in diagnosis and follow-up exam.
