Abstract 【Objective】To analyze the CT features and postoperative survival status of patients with renal clear cell carcinoma. 【Methods】From July 2015 to July 2017, 93 patients with renal clear cell carcinoma were selected. All patients underwent CT examination before operation and pathological examination after operation. According to the results of postoperative pathological examination, they were divided into observation group (high-grade renal clear cell carcinoma, n=37) and control group (low-grade renal clear cell carcinoma, n=56). The patients in both groups were scanned with GE Linght?speed 16 slice spiral CT. The results of CT examination were analyzed by two doctors with intermediate title or above in imaging department. The general data of the two groups were compared, mainly including: gender, age, tumor location, tumor stage. The tumor size, lobulation, hemorrhage, necrosis, capsule and CT value of the two groups were compared. The follow-up time was 1~5 years. The results of death, metastasis and survival were compared between the two groups. 【Results】There was no significant difference in sex, age, tumor location between the two groups (P>0.05). The proportion of patients above T2 in the observation group was higher than that in the control group, the difference was statistically significant (P<0.05). There was no significant difference in maximum diameter, lobulation or none, CT value of enhanced scan in each periodand and bleeding necrosis , etc between the two groups (P>0.05).The CT value of the control group was lower than that of the observation group, and the integrity of the capsule was higher than that of the observation group (P<0.05). The survival rate of the control group was lower than that of the observation group (P<0.05). 【Conclusion】The capsule of high-grade clear renal cell carcinoma is often incomplete, and the CT value of plain scan is high, which indicates that the degree of tumor deterioration is high, which is closely related to the prognosis of patients.
