Analysis of morphometric parameters of children’s kidneys according to ultrasound data

Abstract

Objective. To identify the features of morphometric indicators of children’s kidneys according to ultrasound data, depending on height and age.Materials and methods. Morphometric indicators of the kidneys of children, according to ultrasound examination protocols of 280 male and female children aged 0 to 16 years.Results. The study revealed that in all studied groups of children, the length of the left kidney was greater than the right. The most intensive increase in length occurs at heights of 60–90 cm and 150–170 cm. When analyzing gender differences in kidney growth in length, it was found that in both girls and boys the first “jump” in kidney growth is observed when the length of children is from 60 to 90 cm, and both buds grow at the same rate. The second “jump” in the increase in kidney length occurs at heights of 130–160 cm and 140– 170 cm. These changes in kidney length coincide with the intensive growth of the child in the first three years of life, and then with the onset and course of puberty. Based on the data obtained, it was revealed that the most significant increase in kidney parameters occurs in the first year of life. Thus, by the year of life, the length and width of the kidney increased by 20 %, and thickness by 10 %. By the 4th year of life, with average height (100 cm), length and width increased by another 20 %, and thickness by 32 % from the original.
