CT在输尿管肿瘤诊断中的价值

The Value of CT in the Diagnosis of Ureteral Tumor

目的探讨CT对输尿管肿瘤的诊断价值。方法回顾性分析2011年8月-2013年7月经手术、病理及免疫组织化学证实的52例输尿管肿瘤患者的CT表现,所有患者均行CT平扫、增强检查,其中13例患者行CT尿路造影检查。结果输尿管肿瘤多发生于输尿管下段(20例),输尿管上段5例,中上段8例,中段11例,中下段8例,病变主要表现为肿块或管壁增厚;间接征象包括肾盂、输尿管积水,膀胱输尿管夹角改变。结论 CT对输尿管肿瘤有很大的诊断价值,CT尿路造影能很直观、多方位显示管壁及腔外情况,对指导临床手术有很大意义。

Objective To discuss the value of CT in the diagnosis of ureteral tumor. Methods We retrospectively analyzed the CT features of 52 patients with ureteral tumor confirmed by operation, pathology and immunohistochemistry between August 2011 and July 2013. All patients underwent CT plain scan followed by enhanced scan, and 13 patients underwent CT Urography imaging. Results Ureteral tumors occurred mainly in the lower ureter（20 cases）, and 5 cases occurred in the upper ureter, 8 cases in the mid-upper ureter, 11 cases in the middle ureter, and 8 cases in the mid-lower segment. The lesions showed a lump or thickening of the wall, and the indirect signs included renal pelvis, ureter, bladder and ureter angle changes. Conclusions CT is valuable in the diagnosis of ureteral tumor. CT Urography can be very intuitive, multi-dimensionally displaying the wall and conditions outside the cavity, which has a great significance in guiding clinical operation.
