The urethra that carries urine from the bladder out of the body contains no bacteria or too few to cause an<unk> . However, any part of the<unk><unk>  can become infected.

During infancy, boys are more likely to develop<unk><unk><unk> s. After infancy, girls are much more likely to develop them. children who have UTIs, however, more commonly have various structural abnormalities of their<unk>  system that make them more susceptible to<unk><unk> . These abnormalities include vesicoureteral reflux (VUR), which is an abnormality of the ureters that allows urine to pass backward from the bladder up to the kidney, and a number of conditions that block the flow of urine. The risk of renal scarring is greatest in infants and may be progressive if there is a delay in diagnosis and management of<unk> . The aims of<unk><unk><unk>  management are to provide symptomatic relief and to prevent renal damage. In the meantime to be able to prevent the recurrences of<unk><unk><unk> , evaluation and looking for any structural or functional predisposing factors.
