Abstract

The reliability of the methods for determining the renal-cortical index (RCI) according to Vuorinen and V. Yu. Bosin was assessed by comparing them with volumetric RCT and RCT obtained by calculating the areas after transferring the image of the kidney and its' calyx-pelvic system on graph paper. 41 cadaveric kidneys of children and adults were examined. RCT according to V. Yu. Bosin was determined in 327 children with pyelonephritis. It was found that in 2/3 children with pyelonephritis, RCT is different from the norm; RCT in children and adults is of the same magnitude; RCT according to V. Yu. Bosin accurately reflects the ratio of the areas and volumes of the calyx-pelvic system and the kidney, which proves its high diagnostic value; Due to the low accuracy in reflecting the ratio of volumes, RCT according to Vuorinen can be used only as an approximate method.
