原发性输尿管癌的影像诊断（附10例报告）

目的：评价原发性输尿管癌的各种影像学诊断方法的价值。方法：10例原发性输尿管癌均为移行上皮细胞癌。男性6例，女性4例，平均年龄67岁。选择应用了静脉尿路造影、逆行尿路造影、肾穿刺造影、B超和CT扫描。结果：肉眼血尿、腰痛和肾积水是本病三大临床表现。静脉尿路造影（IVU）诊断2例（18．18％），逆行尿路造影和肾穿刺造影诊断5例（83．33％），B超对10例均未发现输尿管肿瘤，CT扫描诊断2例。结论：逆行尿路造影为原发性输尿管癌影像学诊断最有价值的方法，CT对肿瘤的分期有一定帮助，B超可做筛选应用。

The imaging diagnosis of primary ureteral carcinoma

To appreciate the value of kinds of imaging methods in the diagnosis of primary ureteral carcinoma. Methods 10 cases with transitional carcinoma were confirmed by pathology. There were 6 males and 4 females cases, the mean age was 67. Intravenous pyelography, retrograde pyelography, punclurtio pyelography, ultrasound and CT were selectively used. Results Hematuria, flank pain and hydronephrosis were the main presentations of the patients. 2 cases were diagnosed by IVU(18. 18%), 5 cases by retrograde pyelography and puncturtio pyelography (83. 33% ) . The carcinoma of ureter was not found out by ultrasound in 10 cases. 2 cases were diagnosed by CT scan. Conclusion Retrograde pyelography is the most useful method in diagnosis of primary ureteral carcinoma. CT is helpful to determine the stage of tumor. Ultrasound can be used as a screening method of urcleral carcinoma.
