目的 探讨原发性输尿管癌的影像学特点及诊断价值。方法 对 2 4例原发性输尿管癌的超声、静脉尿路造影 (IVP)、逆行造影及CT检查资料进行回顾性分析。结果 病变显示率为 :B超 45 .8% ( 11/ 2 4) ,IVP 3 7.5 % ( 9/ 2 4) ,RP 88.8% ( 16/ 18) ,CT 62 .5 % ( 10 / 16)。结论 B超检查利于筛选病例 ;肾盂造影是了解肾功能并显示肿瘤的基本检查方法 ;逆行造影对肿瘤的显示和诊断价值最高 ;病变区CT扫描对于定性诊断、了解周围侵犯程度也具有重要价值。
Objective To investigate the imaging features and diagnostic value of primary ureteral cancer. Methods The data of 24 cases of primary ureteral carcinoma by ultrasonography, intravenous urography (IVP), retrograde angiography and CT were retrospectively analyzed. Results The rates of pathological changes were: B ultrasound 45.8% (11/2), IVP 3 7.5% (9/2 4), RP 88.8% (16/18) and CT 62.5% (10/16). Conclusions B-ultrasound is beneficial to the screening of patients. Pyelography is the basic method of examining the renal function and displaying the tumor. Retrograde angiography has the highest value in displaying and diagnosing the tumor. CT scan of the lesion area is of great value for qualitative diagnosis and understanding the extent of surrounding invasion.
