1841年,法国病理学家Rayer首先报道了尸体解剖的原发输尿管癌:1902年,Albarran第一次术前诊断了原发输尿管癌。原发性输尿管癌是较少见的,约占泌尿系恶性肿瘤的1％。我国近年来也有报道。我院发现两例,均经手术和病理证实,现报告于后;并结合文献复习,对原发性输尿管癌的临床表现、X线征象及检查方法进行讨论。 In 1841 French pathologist Rayer first reported autopsy of primary ureteral cancer: in 1902 Albarran first diagnosed primary ureteral cancer preoperatively. Primary ureteral cancer is rare, accounting for about 1% of urological malignancies. Our country has also reported in recent years. Two cases were found in our hospital, both confirmed by surgery and pathology, are reported later; combined with the literature review, the clinical manifestations of primary ureteral cancer, X-ray signs and examination methods are discussed.
