目的探讨多层螺旋CT尿路成像(MSCTU)对输尿管恶性病变的诊断价值。方法 37例输尿管恶性病变患者进行了MSCT检查,包括平扫、肾皮质期、肾实质期、肾盂排泄期扫描,再根据输尿管显影情况进行延迟扫描,将原始图像传输至工作站进行后处理获得MSCTU的图像资料。结果本组病例中,输尿管癌12例,肾盂癌或膀胱癌累及输尿管13例,邻近组织恶性肿瘤侵犯输尿管12例,输尿管恶性病变在MSCTU主要表现为病变段输尿管软组织肿物影,管腔狭窄或闭塞,以及不同程度的尿路梗阻,各种重建方法可以三维显示病变的来源、部位、范围、程度等,并经手术病理证实。结论 MSCTU对输尿管恶性病变的定位、定性诊断有重要价值。
Objective To investigate the diagnostic value of MSCTU in the diagnosis of malignant ureter. Methods Thirty-seven patients with malignant ureteral lesions underwent MSCT, including plain scan, renal cortical, renal parenchyma, and renal pelvis excretion scanning. Delayed scanning was performed according to the development of the ureter. The original image was transmitted to the workstation for MSCTU Image data Results In this group of patients, ureteral cancer in 12 cases, renal pelvis or bladder cancer involving the ureter in 13 cases, adjacent tissue malignant tumor invade the ureter in 12 cases, malignant ureter in MSCTU mainly for the lesion ureter soft tissue tumor, stenosis or Occlusion, and varying degrees of urinary tract obstruction. Various reconstruction methods can display the source, location, extent, degree of three-dimensional lesions and the like, and are confirmed by surgical pathology. Conclusion MSCTU has important value in the localization and qualitative diagnosis of ureteral malignant lesions.
