In the present cross-sectional assessment, the prevalence ofRCC subtypes in a sample of Iranian patients diagnosed with RCC which have undergone nephrectomy surgerybetween years 2014 to 2019 in a referral medical center has been investigated. We have studied 68 patients,including 47 male and 21 female individuals with an average age of 55. The patients have been studied for de-mographic and pathologic information such as age, sex, tumor size, tumor subtype, TNM staging, Fuhrmannuclear grading, and other pathological information.
