The study aimed to review the variants of renal artery division and the formation of renal veins in the renal hilum according to the data of corrosive preparations. The authors studied 124 polychrome corrosive renal vessel preparations. The preparations were subjected to three-dimensional scanning. The three-dimensional projection and topographic and anatomical features of the structure of the arterial and venous renal vessels were determined. As a result, the authors determined the di- and trichotomous variants of the division of the renal artery, A. renalis, into the branches of the 2nd order, that is, zonal arteries, a. zonal, (II). It was revealed that in 70.9% of cases the renal artery in the renal hilum was dichotomously divided into zonal arteries, (a. zonal) (II), wherein 59.6% of cases, the authors observed division of the renal artery into ventral and dorsal branches, further dividing into the ventral and dorsal parts of the renal parenchyma. In the venous system of the kidney, it was found that in 58.8% of cases, the renal vein, V. renalis (I), was formed from two venous vessels in the renal hilum, wherein 36.4% of cases, the renal vein was formed from the superior and inferior polar veins relative to the horizontal plane, and in 22.4% of cases, it was formed from the ventral and dorsal veins. It was revealed that in 36.1% of cases, the main renal vein, V. renalis (I), in the renal hilum was formed from three venous vessels, where several variants were found.
