Children can, and do, get urinary tract infections. As in adults, a urinary tract infection is a bacterial infection of the urethra, ureters, bladder, or kidneys. The condition is much more common in girls than in boys.
In children, there is a significantly increased risk of kidney damage related to urinary tract infections. Vesicoureteral reflux is an abnormality that can lead to serious kidney infections. With this condition, urine can travel backward to the kidneys from the bladder. Bacteria can travel with the urine, presenting a serious infection risk.
Urinary tract infections in children can be caused by blockages in abnormally narrow portions of the urinary tract. It is best to diagnose and recognize these abnormalities early in children as they can lead to recurring infections.
