摘　　要：目的评价多层螺旋CT平扫及重建对输尿管结石的诊断。方法对23例疑诊输尿管结石患者行多层螺旋CT平扫，多平面重建（MPR）及曲面重建（CPR）。结果23例重建图像均清楚显示输尿管病变，22例诊断输尿管结石，其中21例显示结石大小、位置、输尿管不同程度扩张及管壁增厚，1例输尿管癌示输尿管内软组织密度影。结论多层螺旋CT平扫及重建可获得良好的输尿管图像，对输尿管结石有很重要的诊断价值。Objeetive To evaluate the diagnostic efficacy of multislice spiral CT（MSCT） in diagnosis of ureterolithiasis. Methods 23 patients suspected with ureterolithiasis were examined with MSCT. The post--processing methods used in our studies were multiplanar reeonstruction（MPR） and curved planar reeonstruction（CPR）. Results The lesions of ureter were showed by MSCT in all cases, including ureterolithiasis in 22 patients, the size, location of the lithiases, the expanding ureter and thickening walls of ureter were showed by MSCT in 21 patients,one case of ureteral cancer,which appeared as soft tissue density inside the ureter on CT. Con- clusion Multislice spiral CT is valuable in diagnosis of ureterolithiasis.
