Abstract

The aim of the study was to carry out a three-dimensional quantitative analysis of blood supply variants of kidney segments during dichotomous division of the renal artery. The study prepared 116 corrosive preparations of human kidney arterial system, followed by 3D scanning to obtain digital models. It identified types of branching of the main branches of the renal artery in three-dimensional projection, a number of vessels of the branches of the renal artery of different orders, depending on the types of branching of each main branch. The study 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 in a kidney, regardless of the type of two-zone blood supply, in the nutrition of pole segments, functions 1 segmental artery (50.1 %), 2 arteries (35.3 %), 1 artery originating from the renal artery (7.5 %) and 1 artery from the aorta (6.2 %). In the loose type of branching of pole arteries, pole segments have 2 segmental arteries more often than in the main one. On average, with this type of branching, they are more often involved in feeding pole segments than in the trunk type (76.5 % and 23.5 %), respectively. In the upper anterior and lower anterior segments, they branch on average: 1 segmental artery (91.1 %) or 2 arteries (8.8 %). In the posterior segment, on average, they branch: 1 artery (86.7 %), 2 arteries (12.2 %), 3 arteries (1.6 %), which is important to take into account when performing surgical interventions on the kidneys.
