目的：分析２７例输尿管癌的临床和影像学资料，提出其影橡学检查的程序和鉴别诊断。方法：男２７例，女７例；年龄２８～７０岁。２７例均有腹平片及排泄性尿路造影，其中１６例逆行尿路造影，８例ＣＴ检查。结果：９例腹平片患侧肾影增大，２０例患侧肾不显影。７例排泄性和１５例逆行尿路造影显示充盈缺损。８例ＣＴ检查显示输尿管壁不规则增厚３例，结节状２例，３例凸入膀胱形成肿块。结论：排泄性尿路造影能发现患侧肾功能异常或显示肿瘤，逆行尿路造影是诊断输尿管肿瘤的有效方法，ＣＴ扫描能显示肿瘤及与邻近结构的关系
OBJECTIVE: To analyze the clinical and imaging data of 27 cases of ureteral carcinoma and to propose the procedures and differential diagnosis of its influence on ophthalmic examination. Methods: 27 males and 7 females; aged 28 to 70 years. All 27 cases had abdominal plain film and excretory urography, including 16 cases of retrograde urography and 8 cases of CT examination. Results: 9 cases of abdominal plain film increased renal side shadow, 20 cases of the affected side of the kidney does not develop. Seven cases of excretion and 15 cases of retrograde urography showed filling defect. 8 cases of CT examination showed irregular ureteral wall thickening in 3 cases, nodular in 2 cases, 3 cases protruding into the formation of bladder tumor. Conclusion: Urinary tract urography can detect abnormal renal function or show tumor. Retrograde urography is an effective method to diagnose ureteral tumor. CT scan can show the relationship between tumor and adjacent structures
