泌尿系统恶性肿瘤的CT诊断及其病理对照研究

Iconography diagnosis and pathology study of malignant tumor in elderly nrunary system

目的探讨CT检查对泌尿系统恶性肿瘤的诊断价值及其病理对照研究。方法回顾性分析2010年至2013年间接受治疗的有CT影像学资料的肾癌患者78例,肾盂癌患者35例,膀胱癌患者79例,对比分析CT征象与病理结果的关系。结果肾癌的CT检查显示显著强化及中度强化者占92.3%,局限外凸型者占70.5%,CT与病理诊断的符合率为91.0%,术后病理分期与CT分期呈正相关。肾盂癌CT扫描显示病灶强化程度上呈现为明显的不一致,CT分型上有半数分型为局限肾盂型,CT与病理诊断的呈符合率为71.4%。膀胱癌CT增强后扫描显示病灶大多呈现为中等的均匀强化,CT与病理诊断的检测结果符合率为88.6%,病理分期与CT分期呈正相关。结论 CT对肾癌的定性诊断准确率最高,肾癌、膀胱癌的病理分期与CT分期呈正相关,肾盂癌的恶性程度与CT的分期级别呈正相关。

Objective To evaluate the diagnosis value of CT iconography examination for elderly kidney cancer, renal pelvis cancer,bladder carcinoma. Methods Iconography data of 78 patients with kid- ney cancer,35 patients with renal pelvis cancer, 79 patients with bladder carcinoma in our hospital from 2010 to 2013 were retrospectively analyzed, and the relation between clinical manifestation of CT iconography and pathology results were compared. Results In CT examination of kidney cancer, significantly and mod- erate strengthen rate was 92. 3% ,local convex type rate was 70. 5% ,the coincidence rate of CT and patholo- gy examination was 91.0% ,and the pathologic stage after surgery had positive correlation with CT stage. In the CT examination of renal pelvis cancer, the scanning degree was not coincident with strengthen degree of lesion significantly, most CT stage of renal pelvis cancer was local, and the coincidence rate of CT and patho- logic examination was 71.4% ;In the CT examination of bladder carcinoma, the lesion was mostly average strengthen,coincidence rate was 88.6%, pathologic stage after surgery had positive correlation with CT stage. Conclusion Efficacy of CT in the qualitative diagnosis of kidney cancer is most accu- rate. Pathological stage of kidney cancer and bladder carcinoma has positive correlation with CT stage, and malignant degree of renal pelvis cancer has positive correlation with CT stage.
