非增强多层螺旋CT对输尿管结石及并发症的诊断价值

Study the diagnostic value for detecting ureteral calculi and their complications with non-contrast multi-slice spiral CT

目的评价非增强多层螺旋CT(NCMSCT)对输尿管结石及并发症的诊断价值。方法回顾性分析63例输尿管结石患者(其中16例与手术结果对比)的NCMSCT轴位、多平面重建(MPR)及曲面重建(CPR)图像特点,并与手术结果作对比,评价NCMSCT对输尿管结石及并发症诊断的效能。结果NCMSCT对输尿管结石诊断的敏感度为98%,特异度100%,准确率95%;对其并发症诊断符合率为95%。结论NCMSCT轴扫结合重建成像对输尿管结石及其并发症具有较高的诊断价值,可作为临床怀疑尿石症、尤其是术前检查的常规方法。

Objective To evaluate the diagnostic efficacy of non-contrast multislice spiral CT（ NCMSCT）for ureterolithiasis and its complications. Methods The imaging features of 63 patients with ureterolithiasis for NCMSCT on axial location, multiplanar reformation （ MPR ） and camed planar reformation（ CPR ） were analyzed, including 16 cases compared with surgical results. The diagnostic efficacy of NCMSCT for ureterolithiasis and its complications were evaluated. Results The sensitivity of NCMSCT for ureterolithiasis was 98 %, the specificity was 100%, and the accuracy was 95 %. The accuracy for their complications was 95 %. Conclusion NCMSCT images with axial scan,MPR and CPR has important diagnostic value to ureterolithiasis and their complications.It can be a routine method for clinically suggested ureterethiasis, especially for pre-surgery examination.
