Beshulia O. Quantitative anatomy of the intraorganic arterial bed of the human kidney (Anatomy-experimental study)

For the first time a comprehensive study of intraorganic arterial bed of the kidney (IABK) rights in accordance with segmental and dichotomous conceptual models using radiographs revealed previously unknown quantitative patterns of its structure. It was found that IABK is a pseudofraktal structure having a channel tree shape, loose type of branching and evriareal type of the arterial tree. It can be represented as a system consisting of segments and / or branching (dichotomies, trichotomies, kvadritomies). Among the branching dichotomies are: 98% - corrosive preparations and 100% - radiographs. The presence of 4 structural different types of dichotomies: "full asymmetry", "lateral asymmetry", "one-sided symmetry", "full symmetry" was revealed. The presence of two morphofunctional groups of dichotomies: the "optimal" (in accordance with the criterion of HBM Ulyngs (1<n<=1,26) and "non-optimal" (n<=1, n>1,26) was detected. The presence or absence of communication between the relative number of different types and groups of dichotomies and gender and age of investigated persons, side location of the kidney, variant of division of the renal artery and the level of division and generation number of IABK were determined. The presence or absence of communication between gender, age, location of the kidney, renal artery variant division, generation number and level of division of IABK and values of investigated morphometric parameters, the presence or absence of correlations between their values were detected; regression equation describing the nature of the relationship between variables was established. The values of quantitative indicators that can be used as standard morphometric IABK person was determined. Mathematical models that describe human IABK and computer programs that implement them were improved.
