Comporative morphomeric characteristics of the round ligament of the uterus of two groups of fetuses

Abstract

Anomalies in the development of female genital organs account for 4% of all congenital malformations. They occur in 1-3% of the female population, regardless of the preservation of fertile function, and often cause infertility.The purpose of the work is to establish the typical and variant anatomy of the round ligaments of the uterus. Compare the morphometric parameters of the round ligaments of the uterus in two distant fetal groups.Material and methods. The features of the typical and variant anatomy of the round ligaments of the uterus of the fetus were studied on 160 preparations of fetuses and newborns using a complex of morphological research methods: macroscopic, conventional and fine preparation, microscopic, vascular injection, making topographic and anatomical sections, X-ray, computed tomography, three-dimensional computer reconstruction, morphometric and statistical.Results. The round ligaments of the uterus, as well as the own ligaments of the ovaries, in the overwhelming majority of cases, are visualized in the form of dense elongated white cylinders in which it is possible to trace the blood vessels. In our opinion, these ligaments are of unequal decisive importance for establishing one or another topography of the internal female genital organs in the perinatal period. When a displacement of the uterus in the frontal plane was detected, one of the round ligaments of the uterus was shorter, in accordance with the side of its inclination.Conclusions. 1. Already at the beginning of the fetal period, the round ligaments of the uterus provide not only the corresponding inclination of the uterus in the sagittal plane but also its inclination in the frontal plane, giving a defined version of the topography of the internal female genital organs. 2. When comparing the first and second groups of fetuses, there was no significant difference in the length of the right round ligament of the uterus at each of the age stages (p>0.05). However, within the same group, we observe a period of accelerated growth in the length of the round ligaments of the uterus from the 7th month of intrauterine development.
