In this paper is given the overview of current histopathological dividing of renal tumours in adult patients with look on the needs of clinical practice. New classification of renal tumours by UICC and AICC (1997) is given to context with previous knowledge and is replenished by clinical notes relating to diagnosis and treatment. Before the operation is possible to identify only the angiomyolipoma by graphic examinations. If the size of angiomyolipoma is lower than 4 cm, it's enough follow up. In larger angiomy-olipomas and other tumours is needed surgical treatment and a histological typing helps us to establish a prognosis. Oncocytoma is completely benign, angiomyolipoma is also benign (an epitheloid variant can behave malign), chromofobocellular carcinoma and good-differented papillar carcinoma have mostly good prognosis . Worse prognosis is by badly-differented papillar carcinomas and by clear-cell carcinomas. Bad prognosis have also badly-differented clear-cell carcinomas within granular variant. Tubular carcinoma and sarcomatoid variants of carcinomas have very bad prognosis. The facts which were said above is possible to use for indication subsequent oncologic treatment after surgical performance.
