Voroshchuk R. Anatomy and topography of the human renal pyramids at mature and elderly age in projection of renal hilum (voxelized anatomical modeling)

Research was based on the study of 151 isolated anatomical specimens of the human kidneys at mature and elderly age, 20 serial CT and MRI and digital images of topographic slices of the human body from the Visible Human Project. Aim of the study was to establish peculiarities of individual anatomical variability and coordinated topography of the human renal pyramids at mature and elderly ages in projection of the renal hilum. The method of voxelized anatomical modeling was proposed and approbated to resolve the tasks of the study. Based on digital morphometry of cross-sectional anatomical images and 3D voxelized anatomical models of the human kidney there were studied: quantity, forms, structure and coordinated topography of the human renal pyramids. Correlations between renal pyramids’ distribution and kidney volume, their topography and form of the calicopelvic complex were studied. Morphometric classification of renal pyramids is proposed. Anatomical peculiarities of renal pyramids in projection ofrenal hilum were analyzed. Results of the study can be used in anatomical studying and virtual planning of mini-invasive surgery on the kidney. Perspectives of the future researches of renal pyramids were proposed. The results of the research are implemented in practice of Chairs of anatomy, histology of Kharkov State Medical Universities, anatomy, histology, pathoanatomy Chair of Ukrainian Medical Stomatologycal Academy . Branch of usage: medicine, pathological anatomy, normal anatomy, histology, obstetrics.
