The aim of the study was a three-dimensional anatomical analysis of the structural organization of the links of the renal arteries. The material for the study was 116 corrosive preparations of the arterial system of the human kidney, which were subjected to 3D scanning, followed by analysis in the Mimics-8.1 and 3D-max computer programs. It was found that in the kidneys with various types of branching of A. zonal (II) there were differences in the number of vessels of subsequent orders. According to the data of the study, it was concluded that the structural organization of the links of the renal arteries had pronounced anatomical variability at all organization levels, which largely depended on the variant of division of A. renalis (I) against the frontal, horizontal and sagittal planes, as well as the type of intra-organ branching of A. zonal (II). In addition, it has been suggested that the segmental arteries are the interlobular arteries, which in the magistral type of branching are represented by arteries of the third (III) order, and in the dispersal type by the arteries of the third (III) and fourth (IV) orders.

The study aimed to review the topographic and anatomical features of the intra-organ structure of the arterial and venous bed of the human kidney. The study was carried out on 124 polychrome corrosive preparations of the arterial and venous systems of the human kidney. For digitization, the preparations were subjected to 3D scanning. In a computer program, in a 3D projection, the zones of local blood supply to the areas of the renal parenchyma and venous drainage were identified, depending on the variants of the division of the renal artery and the fusion of the renal vein. The analysis of polychrome corrosive preparations of arterial and venous vessels of the kidneys revealed 17 topographic and anatomical variants of the division of the arterial bed and formation of the venous bed of the kidney, where the main trunks in the renal hilum relative to the sagittal, frontal and horizontal planes occupied different positions. The 3D analysis of polychrome corrosive preparations of arterial and venous vessels of the kidneys showed that the great arterial vessels in 30.0% of cases repeated the course of the cognominal venous vessels, both concerning their location in the hilum of the kidney relative to the sagittal, frontal and horizontal planes, and their course, and topography in the parenchyma of the organ.
