Urinary Tract Infection in Children: An Up-To-Date Study.

Abstract

Urinary tract infections (UTIs) are common bacterial infections in children. UTIs may be limited to the bladder or involve the kidneys with possible irreversible damage. Congenital abnormalities of the kidney and urinary tract (CAKUT) are often associated with UTIs; kidney scars have been considered a consequence of untreated UTIs but may be congenital. The mechanism by which bacteria produce inflammation in the urinary system has been intensively investigated. Diagnostic tools, including invasive imaging procedures, have been advocated in infants and small children with UTIs but are not necessary in most cases. Effective antibiotic drugs are available, and prophylactic treatment has been questioned. Several guidelines on UTIs are available, but a simple one for general practitioners is needed.
