Fifteen cases of primary urothelial carcinomas of the ureter are reported (14 transitional cell carcinoma and 1 mixed transitional cell carcinoma and squamous cell carcinoma). There was a clear male predominance (11/4); the peak incidence was in the sixth decade. Most tumors originated from the distal third of the ureter. Multicentricity and high recurrence rate after partial ureterectomy were noted. The clinical signs were hematuria and flank pain. Urine cytology and IVU were diagnostic in a limited number of cases. Retrograde pyelography was very helpful. CT showed to be the image modality of choice for diagnosis and preoperative staging.
报告了15例原发性输尿管尿路上皮癌（14例移行细胞癌和1例移行细胞癌与鳞状细胞癌混合）。男性明显占优势（11/4）；发病高峰在第六个十年。大多数肿瘤起源于输尿管远端三分之一。部分输尿管切除术后观察到多中心性和高复发率。临床症状为血尿和侧腹痛。尿细胞学检查和静脉尿路造影在少数病例中具有诊断价值。逆行肾盂造影非常有帮助。CT被证明是诊断和术前分期的首选影像学检查方法。
