高分辨率薄层CT平扫三维重建对结石性肾绞痛的诊断价值

摘要

Objective:To evaluate high-resolution thin-layer CT scan diagnostic value of three-dimensional reconstruction in stone of renal colic. Methods:AlphaRetrospective analysis of high-resolution thin-layer CT scan three-dimensional reconstruction of group (A) and intravenous pyelography (B group), the sensitivityand specificity of the diagnosisof calculousrenal colic. GroupA70cases,theemergencylinekidney,ureter,bladder thin-layer CTplain and three-dimensional reconstruction, the reconstruction layer from (2~3)mm; B group of 65 patients using iohexol or ioversol intravenous pyelography, renal colic relief.The two groups before the examination, a diagnosis of renal colic. Results:Group A sensitivity for the diagnosis of urinary calculi was 97.1%, specificity 95.6%; group B, the sensitivity of the diagnosis of urinary calculi 61.5% and a specificity of 97.5%.Conclusion:CT scan, high-resolution thin-layer three-dimensionalreconstructioninthediagnosisofacalculusofrenalcolicisanefficient,convenient,reliablemethodofexaminationisworthyofclinical.%　　目的：评价高分辨率薄层CT平扫三维重建在结石性肾绞痛中的诊断价值.方法：回顾性分析高分辨率薄层CT平扫三维重建组(A组)与静脉肾盂造影组(B组)对结石性肾绞痛诊断的敏感性及特异性.A组70例，急诊行肾、输尿管、膀胱薄层CT平扫及三维重建，重建层距(2~3)mm；B组65例，肾绞痛缓解后使用碘海醇或碘佛醇行静脉肾盂造影.两组检查前均诊断为肾绞痛.结果：A组对泌尿系结石诊断的敏感性97.1%，特异性95.6%；B组对泌尿系结石诊断的敏感性61.5%，特异性97.5%.结论：高分辨率薄层CT平扫三维重建在结石性肾绞痛的诊断中是一种高效、便捷、可靠的检查方法，值得临床推广.
