From bacteriuria to the urinary tract microbiome: the evolution of the views of researchers and clinicians

Abstract

The preservation of the human urinary tract integrity in interaction with microorganisms depends on the balance of many components: the viability of nonspecific protective factors of the urinary tract mucosa, the virulence factors of microorganisms, the intensity of the innate immune response of the urinary tract tissue to the presence of microorganisms, the mutual impact of the microand macro-organism upon each other that is directed towards creation of a normal microbiome, and not inflammation. Most of these factors are genetically determined both by microorganisms and humans. The article presents modern data of Russian and foreign literature devoted to the description of factors supporting the homeostasis of the urinary tract in interacting with microorganisms. The authors emphasise a key role of these data in the practice of clinicians, including paediatricians and paediatric nephrologists, family doctors.
