Abstract

The aim of the study was to carry out a three-dimensional quantitative analysis of the variants of blood supply to the segments of the kidneys during dichotomous division of the renal artery. We made 116 corrosive preparations of the human kidney arterial system, followed by 3D scanning to obtain digital models. In three-dimensional projection, we determined types of branching of the main branches of renal artery, number of vessels of the branches of renal artery of different orders depending on the types of branching of each main branch. We determined segmental arteries, their number involved in the nutrition of the renal segments, depending on the types of intraorgan branching in the main and loose types of branching. The morphometric analysis data were processed by the methods of variation statistics. It was found that kidneys with a three-zone (upper pole, lower ventral and lower dorsal) or (lower pole, upper ventral and upper dorsal) blood supply system with a five-segmental structure in the nutrition of pole segments are involved on average: 1 segmental artery (67.1 %), 2 arteries (24.2 %), 1 artery from the main renal artery (7.2 %) and 1 artery from the aorta (1.5 %). In the upper anterior and lower anterior segments, on the average, they branch: 1 segmental artery (86.3 %) or 2 arteries (12.4 %). In the posterior segment, on average, there are branches: 1 segmental artery (82.3 %), 2 arteries (10.3 %) and 3 arteries (6.3 %), which is important to consider when performing segmental resections or organ-preserving kidney operations.
