摘　　要：目的分析MSCT诊断原发性输尿管段移形上皮细胞癌的临床价值。方法选取本院2016年6月至2019年12月收治且经手术病理确诊的38例原发性输尿管段移形上皮细胞癌患者作为研究对象。察肿瘤位置、形态、密度、与周围组织的关系及强化形式等特征,并分析CT检查诊断原发性输尿管段移形上皮细胞癌的准确率。结果38例原发性输尿管段移形上皮细胞癌经MSCT检查共确诊35例,诊断准确率为92.11%;肿瘤位置:左侧18例,右侧20例;输尿管上段9例,中段12例,下段17例。肿瘤横径:0.87~2.14cm,纵向侵犯范围:1.47~5.64cm。CT扫描可见输尿管管壁不同程度增厚,11例可见软组织结节,9例可见软组织肿块。官腔呈偏心性狭窄24例,向心性狭窄14例。输尿管管壁外脂肪间隙可见高密度影。增强扫描强化明显。官腔内可见充盈缺损。38例患者输尿管均可见不同程度积水。结论CT检查可有效显示原发性输尿管段移形上皮细胞癌的影像学特征,诊断准确率高,对早期诊断与鉴别诊断原发性输尿管段移形上皮细胞癌具有较高的临床应用价值。Objective To analyze the clinical value of MSCT in the diagnosis of primary transitional epithelial cell carcinoma in ureteral segment.Methods 38 patients with primary transitional epithelial cell carcinoma in ureteral segment admitted in our hospital from June 2016 to December 2019 and confirmed by surgery and pathology were selected as the research subjects.The characteristics such as tumor location,morphology,density,relationship with surrounding tissues,and enhanced forms were observed,and the accuracy of CT in the diagnosis of primary transitional epithelial cell carcinoma in ureteral segment was analyzed.Results In 38 cases with primary transitional epithelial cell carcinoma in ureteral segment,35 cases were diagnosed by MSCT,and the diagnostic accuracy was 92.11%.The tumors were located on the left side in 18 cases and on the right side in 20 cases;9 cases in the upper segment of the ureter,12 cases in the middle segment,and 17 cases in the lower segment.The transverse diameter of the tumor was 0.87~2.14cm,and the range of longitudinal invasion was 1.47~5.64cm.CT scan showed different degrees of thickening of the ureteral wall.Soft tissue nodules were seen in 11 cases,and soft tissue masses were seen in 9 cases.The lumen showed eccentric stenosis in 24 cases and concentric stenosis in 14 cases.High-density shadows can be seen in the fat space outside the ureteral wall.Enhanced scans show significant enhancement.Filling defects can be seen in the lumen.The ureter was found in 38 patients with varying degrees of effusion.Conclusion CT examination can effectively display the imaging characteristics of primary transitional epithelial cell carcinoma in ureteral segment,with high diagnostic accuracy,It has high clinical application value in early diagnosis and differential diagnosis of primary transitional epithelial cell carcinoma in ureteral segment.
