Urinary tract infections (UTIs) are a serious medical problem. The disease affects a significant percentage of children, including newborns, infants, older children and adolescents. Numerous factors influence the course of UTI and the manifestation of clinical symptoms. UTIs that are diagnosed too late, untreated or poorly treated are the cause of many complications that can pose a serious threat to the health and even life of a child. In the prevention of UTI, in their diagnosis and therapy, an important role is played by nursing staff, who have an obligation to educate child carers on the subject of risk factors, the importance of check-ups in early diagnosis of infections, and rules in force during therapy. It is not without significance to learn skills related to the care of the child's intimate areas, as well as the principles relevant for the prevention of relapses.
