摘要:
目的:分析原发输尿管癌的CT表现,评价64排螺旋CT尿路造影对原发输尿管癌的诊断价值。方法:分析48例经病理证实原发输尿管癌患者64排螺旋CT尿路造影的影像表现,对多层面重建、曲面重建、容积显示(VR)和最大密度投影(MIP)等多种后处理技术结合原始横轴位图像进行综合分析。结果:48例原发输尿管癌患者,发生于上段5例、中段12例、下段24例,7例为多发。28例可见输尿管梗阻,梗阻上段输尿管均有不同程度扩张和肾盂积水。结论:64排螺旋CT尿路造影准确评估原发输尿管癌的位置、形态、范围及周围组织改变,可靠、准确,可作为目前临床检查原发输尿管癌的首选影像诊断方法之一。

Abstract:
Objective: To study the feature of CT in primary ureteral carcinoma,to evaluate the diagnostic value of 64 multi-detector helical CT Urography in primary ureteral carcinoma.Methods: The CTU finding of primary ureteral carcinoma were analysed in 48 cases.The data was transmitted to ADW4.2 workstation,and reconstructed by MPR,CPR,VR,VE and generally analyzed with original axial images.Results: Of 48 primary ureteral carcinoma cases,5 cases are located in upper segment of the ureter,12 cases in middle segment,24 cases in lower segment and multiple is 7 cases.28 cases presented urinary obstruction,distention and hydronephrosis.Conclusion: The location,the shape,the spectrum of primary ureter carcinoma and change of surrounding tissue were clear in 64-MDCTU,is reliable and accurate in evaluating tumor,gradually become one of the first modality diagnose in primary ureteral carcinoma.
