Clinical and echographic characteristics of the uterus, ovaries and endometrium in healthy girls and in girls with UMC

Juvenile uterine bleeding in the structure of gynecological diseases in girls is 16.6% - 48.1%, relapses up to 19.3% [2, 4, 5, 6, 7, 9, 10, 12, 15, 17]. In recent decades, in gynecology, ultrasound research has gained particular importance both in normal physical and sexual development, and in reproductive disorders. The first report on the successful use of ultrasound in children and adolescents to determine the status of the internal genital organs, both normal and in pathology, belongs to M. Gates (1978). Using ultrasound,it is possible to trace the growth and development of the uterus and ovaries in girls from the time of onset menarche to 18 years. The method is painless and safe for patients, which allows multiple observations in dynamics. Safety and high resolution of the method indicate great potentialities of using ultrasound in pediatric gynecology [1, 2, 3, 6, 13, 15, 17]. The literature contains detailed data on the echographic anatomy of the internal genital organs in early childhood and at different periods of puberty [18]. The ability to obtain complete and reliable information about the condition of the pelvic organs in adolescents with the help of ultrasound made it possible not to use such complex, invasive and expensive research methods as laparoscopy and hysteroscopy (V.P. Kharchenko et al.).
