【摘要】目的探讨64层螺旋CT尿路成像技术对输尿管疾病的诊断价值。方法对126例临床怀疑输尿管梗阻患者进行64层螺旋CT容积扫描,将原始数据传至工作站,应用MPR、CPR、MIP、VR进行图像后处理。结果输尿管结石67例,输尿管先天性变异及畸形26例,输尿管炎性狭窄6例,肾输尿管结核2例,输尿管癌4例,副肾动脉压迫输尿管1例,膀胱疾病累及输尿管8例,邻近器官病变累及输尿管致输尿管梗阻6例,盆腔疾病术后粘连致输尿管梗阻5例,直肠癌术后输尿管瘘1例,以上病例均得到手术、输尿管镜检查和临床证实。结论 MSCTU通过MPR、CPR、MIP、VR技术能清楚输尿管疾病的位置和形态,在输尿管疾病的诊断方面具有独特的优势。

[Abstract] Objective To explore the diagnostic value of 64-slice puted tomography urography(MSCTU) in ureter diseases. Methods MSCTU was performed in 126 patients with ureter obstruction suspicious clinically, the volume data of all patients were reconstructed on work station(Vitrea 2) with the techniques of multiple plane reformation(MPR), curved planar reconstruction(CPR), maximum intensity projection (MIP) and volume rendering(VR). Results Among the 126 cases, there were 67 cases of ureteral calculus, 26 cases of congenital variation and deformity, 6 cases of inflammatory stenosis, 2 cases of ureter and kidney tuberculosis, 4 cases of primary ureteral cancer, 1 case of accessory renal pression at right ureter, 8 cases of secondary ureter dilatation involved by bladder diseases, 11 cases of ureter obstruction involved by the diseases of ans and post-operative adhesion, 1 cases of uretero-rectal fistula. All cases were confirmed by surgery, ureterosc
