报告原发性输尿管癌１８例，病理确诊均为移行上皮细胞癌。作者认为静脉尿路造影、膀胱镜、逆行肾盂造影、肾盂穿刺顺行造影或ＣＴ联合检查是主要的诊断方法。肾盂穿刺顺行造影是对患侧肾不显影者最为重要的诊断手段。１５例行患侧肾、输尿管全长及膀胱袖状切除，３例行输尿管部分切除＋输尿管与膀胱再植术。术后应定期膀胱内灌注化疗药物。术后１年内死亡６例，２年内死亡６例，生存≥５年者６例。提示生存率与肿瘤的病理分级分期密切相关

The author believes that intravenous urography, cystoscopy, retrograde pyelography, peritoneal radiography or CT combined examination is the main diagnostic method.
