摘　　要：目的:在静脉尿路造影(IVU)无法明确输尿管梗阻原因时,评价多层螺旋CT(MSCT)泌尿系成像技术对输尿管梗阻病变的诊断价值。方法:40例经IVU显示为不明原因输尿管梗阻患者即刻接受MSCT平扫,将所得数据资料传至工作站,采用最大强度投影(MIP)、多平面重组(MPR)、曲面重组(CPR)、表面遮盖显示(SSD)或容积重组(VR)等后处理技术,重组泌尿系三维立体图像。结果:40例IVU无法明确输尿管梗阻原因患者中采用MSCT轴面结合三维重组图像能从多个角度清楚地显示尿路全程及其周围组织结构,并显示输尿管梗阻部位的状况,MSCT尿路造影(MSCTU)可很好地弥补IVU检查的不足。结论:与IVU比较,MSCTU图像清晰,对输尿管梗阻性病变有着很高的临床应用价值,可使输尿管病变诊断准确率得到明显提高。Objective：To evaluate the role of multislice computed tomography （MSCT） in the diagnosis of urinary tract obstructive disease when intravenous urography could not determine the diagnosis. Methods： A total of 40 consecutive patients with unknown nature of ureteral obstruction underwent MSCT plain scan immediately after IVU examination, The data were transmitted to the workstation,and 3D images of the urinary system with maximum intensity projection （MIP）, multiplanar reformation （MPR）, curved planar reformation （CPR）, shaded surface display （SSD） or volume rendering （VR） were reformatted. Results： Of all the 40 patients, 3D reformatted images combined with axial view could show the whole course of the urinary system and the surrounding structures clearly, and display the ureteral lesions from multiple projections. Conclusion：MSCT urography has high image quality and is superior to IVU in diagnosing ureteral obstructive disease. It has great value the clinical diagnosis of the urinary system disease.
