Urinary tract infections are one of the most common and widespread infectious diseases. A certain role in etiopathogenesis may play genetic predisposition, as well as a decrease in antiadhesive properties and an increase in urothelium permeability due to incompetence of bladder glycosaminoglycan layer. The prevalence of infectious diseases increases significantly with age, as well as in patients with chronic diseases. The introduction of modern biotechnology has allowed clinicians to greatly expand therapeutic armamentarium, while having a number of advantages, including minimal frequency of complications and adverse events, the possibility for long-term use, accessibility, and etc. Priority research areas include the study of toll-like receptors, which are transmembrane proteins that provide pathogen recognition and activate the immune response. The role of these receptors in the development of the immune response to urinary tract infections was evaluated in our study, which allows to predict the course of the disease and to increase treatment efficiency.
