摘　　要：目的:比较多层螺旋CT尿路造影(MSCTU)与静脉尿路造影(IVU)诊断输尿管病变的价值。材料和方法:31例患者分别行腹部加压IVU及腹部加压MSCTU。将MSCTU获得的图像传输至独立工作站,并进行三维(3D)、最大密度投影(M IP)、多平面重组(MPR)、曲面重建(CPR)等技术处理。结果:MSCTU诊断符合率、肾脏显影率及输尿管梗阻扩张显示率分别比IVU高41.9%、16.1%和6.5%。结论:MSCTU诊断输尿管病变的诊断、判断肾功能和显示输尿管梗阻扩张程度均优于IVU。Parpose： To study the diagnostic value between conventional intravenous urography （IVU）and Multi-slice CT urography （MSCTU） in ureteral lesions. Materials and Methods： 31 patients underwent IVU and MSCTU respectively. After MSCTU, images were transmited to workstation and three-dimensional （3 D）, muhiplanar maximum intensity projection （ MIP）, multiplanar reconstruction （MPR） and curve planar reconstruction （CPR） techniques were postprocessed to obtain urographic views. Results： The diagnostic accurate rate, the showing rate of kidney and the detecting rate of the ureteral dilation and obstruction of MSCTU was 41.9%, 16.1% and 6.5%, and was more than IVU, respectively. Conclusion： MSCTU is better than IVU in diagnosis of ureteral lesions, assessment of renal function and detection of ureteral dilation and obstruction.
