Background. Ultrasound diagnosis (echography) is now one of the main diagnostic methods used in medical practice. Based on the results obtained by ultrasound (ultrasound), a plan for further diagnostic examination of the patient can be made and/or treatment policy can be determined for a specific patient.&#x0D;Purpose. Studying the echographic features of the internal genitalia in adolescent girls with abnormal uterine bleeding depending on the time of the disease debut and hormonal levels.&#x0D;Materials and methods. Two hundred and eighty-nine adolescent girls with abnormal uterine bleeding were examined at the age of 11–17. The patients were divided into three groups. Group I included 163 adolescents with manifestation of the disease with menarche or in the first year of menstrual function. Group 2 included 65 girls in whom AUB arose in the second and later years of the existence of menstrual function. Group 3 included 61 patients with an unsteady menstrual cycle. LH, FSH, PRL, E2, T, IRI, IPFR-1, SHPS were determined in the blood serum. The longitudinal, transverse and anteroposterior dimensions of the uterus and ovaries were measured.&#x0D;Results. The evaluation of the ultrasound data of the pelvic organs of girls with AUB was carried out. It was revealed that the parameters of the uterus within the age norm were recorded only in 35 % of patients. The least frequently in girls with previous oligomenorrhea (29.5 %). More than a third had persistent ovarian follicles or cysts and 62.8 % had an increase in the intrauterine M-echo. The dependence of the size of the uterus on the pattern of hormones was revealed. A mathematical analysis of associative relationships of the hormonal background and echographic parameters of the uterus is presented.&#x0D;Conclusions. Ultrasound examination of the pelvic organs is a useful tool in identifying the morphological features of the uterus and ovaries, complements the endocrine profile of patients, which increases the diagnostic accuracy, and its results serve
