目的 研究输尿管病变在螺旋CT三期扫描中的成像特点及其临床应用价值.方法 回顾分析76例经临床证实的输尿管病变的螺旋CT三期扫描所获得的横断及CTU影像.结果 76例输尿管病变中,输尿管肿瘤24例,造成重度尿路梗阻,并町见肿块的形态,大小,数目的 多少及上下输尿管壁的炎症浸润情况;输尿管结石26例,"边缘征"显示清晰;输尿管炎症10例,均能显示输尿管壁的增厚程度及明显强化特点;输尿管结核8例,均继发于肾结核,输尿管壁不均增厚,僵直,管壁轻中度强化;输尿管先天畸形3例;外源性因素5例,均能很好的显示其概况.结论 输尿管病变在螺旋CT三期扫描中均可见其特征表现,对其诊断及鉴别诊断具有重要意义.%Objective To assess the imaging characters and clinical applications of triphasie spiral computer tomography (CT) scanning in ureteral lesions. Methods We analyzed of 76 eonseeutive eases of elinieaUy evidenced ureteral lesions using the cross - sec-fional images and CTU derived from triphaaie spiral CT scanning retrospectively. Results Twetny - four cases of 76 ureteral lesions pa-tients were diagnosed as ureteral tumor, resulting in severe urinary tract obstruction. The shape, size, number, regional ureter wall in-flammatory infiltration of visible mass were verified as well. Twetny- six cases were caused by ureteral stones. The "edge" sign was shown clearly. Ten cases were ureteral inflammation, characterized by different ureteral wall thickening and enhancement feature. Eight cases were ureteral tuberculosis that secondary to renal tuberculosis. Uneven ureteral wall thickening, stiffness and mild to moderate densi-ty were shown in CT scanning. Ureteral congenital malformations were found in 3 patients. The other five cases were caused by exogenous factors. CT scanning could identify the mass general profile. Conclusion Triphasic spiral CT scanning plays an important role in ureteral lesions diagnosis and differentiation from other similar diseases.
