Regularities of renal calyces morphometry in childhood, adolescence and early adulthood

Abstract

Recent studies of human kidney calyces developed in several directions. Evolution of pyelocaliceal complex in postnatal ontogenesis (from birth to old age), as well as the development and the topography of the organs and structures of the retroperitoneal space in early ontogenesis were studied without taking into account morphometric parameters of individual renal calyces. Dynamics of morphometric parameters of renal calyces were studied only for the age group of mature and elderly people. Morpho-functional feature of children, adolescents and youth is the "evolutionary gap" in increasing of linear and volume parameters of renal calyces from increase in volume of renal parenchyma and pyelocaliceal complex (only to a third morphometric transition of kidney, ie in teenage and youthful age, we registered a statistically significant change of linear and volumetric parameters of renal calyces).
