Соотношение высоты селезенки к высоте левой почки у детей и подростков по данным прижизненной визуализации

Abstract

Objective: to establish age and gender patterns of changes in the ratio of spleen height to left kidney height in children and adolescents of Orenburg region according to the data of intravital imaging. Materials and methods. Abdominal CT scans of 75 children without visible pathology were examined. The surveyed were divided into 4 age groups: early childhood, first childhood, second childhood, adolescence. The study was performed on 16-slice computed tomographs with the determination of the height of the spleen and the left kidney and calculation of the ratio of these parameters. The obtained data were subjected to variation-statistical processing with the determination of the mean value (M), standard error (m) and the reliability of differences according to the Student's t-test. Results. It was found that the indicator of the height of the spleen among all the examined changed from 7.1±0.3 cm in the 1st group to 10.2±0.3 cm in the 4th group (p=0.001). The height of the left kidney in the 1st group was 7.6±0.1 cm and increased by the 4th group to 10.2±0.1 cm (p=0.001). The smallest value of the ratio of the height of the spleen to the height of the left kidney among girls and boys was found in children of early childhood and was 0.90±0.10 and 0.93±0.04. The maximum value of the indicator among girls was 1.05±0.08 in children of the second childhood, and among boys, 1.05±0.07 in children of first childhood. Conclusion. There are no significant differences between the indicators of the ratio of spleen height to left kidney height, depending on age, and there are no gender differences within the group.
