RT Journal Article SR Electronic T1 Fifteen-minute consultation: Why and how do children get urinary tract infections? JF Archives of disease in childhood - Education & practice edition JO Arch Dis Child Educ Pract Ed FD BMJ Publishing Group Ltd and Royal College of Paediatrics and Child Health SP 244 OP 247 DO 10.1136/archdischild-2018-315023 VO 104 IS 5 A1 Kjell Tullus YR 2019 UL http://ep.bmj.com/content/104/5/244.abstract AB This paper describes urinary tract infections (UTI) from the perspective of a disturbed balance between bacterial virulence and host defence. In some children, a UTI is caused by a virulent Escherichia coli, while in other cases children with abnormal renal tracts can get infected by almost any bacteria. Such knowledge can help in guiding treatment, investigations and follow-up of a child with a UTI.
