Abstract Objective: To evaluate the influence with different methods of grouping on detecting pseudocapsule sign of clear cell renal carcinoma(CCRCC) diagnosed by CEUS. Methods: The features of CEUS of 87 CCRCCs in 83 patients confirmed by pathology were retrospectively analyzed. Samples were divided into different groups by different methods of grouping criteria. The frequency of pseudocapsule sign of CCRCCs diagnosed by CEUS was calculated and compared in different methods of grouping to analyse their influence on detecting pseudocapsule sign. Results: Among all the seven methods of grouping, there was statistically significant difference between the third, fifth and sixth grouping methods for detecting pseudocapsule sign of CCRCCs diagnosed by CEUS. No differences were found in the other grouping methods. Conclusion: Detection of pseudocapsule sign of CCRCCs diagnosed by CEUS will be different according to different methods of grouping. The methods of grouping can affect the detection of pseudocapsule sign of CCRCCs diagnosed by CEUS.
