BACKGROUND. Extragenital diseases, including recurrent urinary tract infections, have an adverse effect on the reproductive health of children and adolescents. Vaginitis and menstrual cycle disorders, including primary oligomenorrhea, predominate in the structure of gynecological morbidity of minors suffering from recurrent UTIs.THE AIM: to study the role of stress reactions in the genesis of various variants of menstrual cycle disorders in minors suffering from recurrent UTIs to improve the dispensary management of this cohort of patients. PATIENTS AND METHODS. A prospective study was conducted in 98 adolescent girls aged 16 to 18 years. Taking into account the nature of the clinical course of UTI, all the subjects were divided into 3 groups: group 1 (n=41) – patients with UTI; group 2 (n=27) patients with frequent recurrence of UTI (more than 3 times a year (rIMP); group 3 (n=30) – minors, 1, 2 health groups with no IPM episode. A specialized gynecological examination, functional diagnostic tests, ultrasound examination of the placemark and ovaries, determination of cortisol, norepinephrine, adrenaline by enzyme immunoassay were carried out. Statistical analysis was performed using the program "SPSS Statistics 17.0 for Windows".RESULTS. Anovulation was observed in patients with frequent recurrence of UTI. Copious and prolonged menstruation, uterine bleeding and primary oligomenorrhea were observed only in patients with recurrent UTIs. In this cohort, inflammatory gynecological diseases take a chronic course. Polycystic ovarian syndrome (40.7 %) and chronic salpingoophoritis (44.4 %) were often detected in patients with frequently recurrent UTI. In patients suffering from UTI, in contrast to the data of the comparison group, there were significant violations of the nature of adaptive reactions, and changes in antistress reactions and their levels differed depending on the variant of the course of the microbial-inflammatory process. In patients with rare relapses of UTI, antistress reactions of a high level of reactivity prevailed, but there were reactions of calm and increased activation, training that took place at low levels of reactivity.CONCLUSION. Adaptive-compensatory disorders were revealed in almost every patient with recurrent UTI. Considering that stress is especially pathogenic during puberty, when hormonal and psychophysiological restructuring of the body occurs, prevention and complex therapy of microbial-inflammatory diseases of the urinary system in this category of patients should be carried out taking into account the formation of reproductive function and the severity of adaptation reactions.
