原发性输尿管癌的诊断:传统尿路造影术与CT、MRI比较(附15例分析)

目的：评价传统尿路造影、ＣＴ与ＭＲＩ在原发性输尿管癌诊断中的价值。材料和方法：本１５年（１６个部位）经手术和病理证实的病例中，１３例（１４次）行静脉肾孟造影（ＩＰＶ），６例（７例）逆行肾盂造影；１例肾穿刺造影；６例ＣＴ检查，其中４例加增强扫描；２例ＭＲＩ检查，先以自旋回波（ＳＥ）序列做轴有冠状面Ｔ１和Ｔ２加仅扫描，再做冠状面磁共振尿路选影（ＭＲＵ）．结果：传统尿路造影共８例９次（６４％）获得术前

Diagnosis of Primary Carcinoma of the Ureter: A comparision of Traditional Urography to CT and MRI (An Analysis of 15 Cases)

To evalanate the diagnostic value of using traditional urography, CT and MRI in primary carcinoma of the ureter. Materials and Methods 15 patients (16 lesions) with primary carcinoma of the ureter confirmed by surgery and pathology were reviewed. Of which, 13 cases (14 lesions) had intravenous pyelography (IVP),6 cases (7 lesions) had CT scans (with contrast-enhanced n = 4), 2 cases had MAI.After axial and coronal T1 and T2 weighted with spin-echo (SE) images were done, MR urography (MRU)was dong using a heavily T2 weighted turbo SE sequence Results:8 cases (9 lisions) of 13 cases (14 li-sions) were examined using traditional urography , we were able to obtain diagnosis before surgery (64% ). In those cases with CT and MRI examinataion, the diagnosis was estabished because of showed level and cause of ureteral obstruction. Especially MRU urogramlike images in revealing obstraction of urinary tract were more clear. Conclution :Traditional urography is still the first and primary tool CT and MRI may be helpful to comfirm diagnosis and clinic staging. Following traditional urography, MRU is the most suitabe imaging modality for the urinary tract.
