Inclusion Criteria: 1. Patients who underwent an abdominal CT examination. 2.

Exclusion Criteria: 1. Patients refuse to undergo recommended follow-up, biopsy, or surgery, which precluded definitive diagnosis of the renal lesion. 2. Absence of complete pathological confirmation for lesions suspected to be malignant. 3. Patients have received any form of prior treatment for the renal lesion. 4. Poor image quality that hampered diagnostic evaluation.
