[Functional dependence of the size of the left kidney to the size of the right kidney and the opposite].

In this study anatomical variations of shape, size and relation of the kidneys have been analyzed. It has been carried out on 33 pairs of the human adult kidneys of both sex, randomly chosen. It has determined size, width and thickness of the kidney. The kidneys are very variable organs in the size and in the shape. Reduced largeness of the kidney and enlarged kidney are forms of variations of size. Reduced largeness of the left kidney has been found in 18.18%, and enlarged one in 24.24%. Reduced largeness of the right kidney has been found in 24.24% and enlarged one in 21.21%. Two types of the shape were presented: fetal lobularness and lobarnes of the kidney. The shape of left kidney was variable in 39.39%, fetal lobularness was present in 33.33%, and lobarness in 6.06%. The shape of right kidney was variable in 30.30%, foetal lobularness was present in 27.27%, and lobarness in 3.03%. All parameters that determine the size of kidneys show statistically high positive correlation. It means that mutual functional dependence is present, what made it possible from the size of right kidney calculating the size of left kidney and opposite.
