Shklyar A. Anatomy of the renal hilus at the stages of postnatal human ontogenesis.

Object of the research: human renal hilus. Purpose of the research: study of typical anatomy of the renal hilus with substantiation of the system of morphometric indicators for morphotype of the renal hilus at the stages of human postnatal ontogenesis. Methods of research: anthropometry, organometry of the kidney, coordinate morphometry of renal cuts in area of its hilus, methods of coordinate anatomy, methods for determination of the shape and position of the renal hilus in conditions of sectional biometry. Statistic methods (index, variation statistics), mathematical (polynominal analysis), correlation-regression analysis, methods of component analysis of morpho-logical structure. Practical significance of the obtained findings: a systemic approach to the study of morphometric changes of the renal hilus at the stages of postnatal ontogenesis is realized, influence of sex and age on anatomical – structural organization of the human renal hilus is studied. The obtained data concerning linear dimensionsand individual anatomical vari-ability of the renal hilus at the stages of postnatal on-togenesis can be used for perfection of organo-preserving operations, as well as for early diagnos-tics or functional renal disorders. The system of standardized recording of morphometric indicators in the form of morphochronograms of the renal hilus and human kidney is substantiated, which allows to analyze variability of anatomical structures at the stages of human postnatal ontogenesis. Scientific novelty: for the first time it is proved that there is variability of the shape and position of the renal hilus at the stages of postnatal ontogenesis, that depends on the complex of factors and can be revealed using the author’s method (Pat. No.68299 A, Ukraine). It is determined that the shape and position of the renal hilus depend on sex, age, somatotype, which can be taken into account in system using the author’s technique (Pat. No. 66287 A, Ukraine). It is proved that renal organometric indices in combination with indicators of its hilus reflect stages of human postnatal ontogenesis, which can be used for solution of specific problems of sectional morphometry (Pat. No. 66287 A, Ukraine). An in-tegral model of morphogenesis of the renal hilus is created and regularities of its individual anatomical variability in postnatal ontogenesis of the adult are studied. Degree of introduction: the data concerning anatomy of the renal hilus at the stages of human postnatal ontogenesis and worked out techniques are used in morphological studies, as well as in educational process at the departments of anatomy, morphological and surgical types of higher medical educational establishments and in the system of after-graduating education of the doctors. Sphere of application: normal anatomy, operative surgery and topographical anatomy.
