Urinary tract infections in young children need to be treated with sensitive antibiotics, usually penicillin or cephalosporin. Young children are prone to bacterial infections due to their physiological characteristics, such as in girls due to the wide, short, straight urethra and its proximity to the anus; boys are also prone to urinary tract infections due to a long foreskin or prepuce. For treatment, penicillin or cephalosporin antibiotics, such as amoxicillin and cefixime, should be applied under medical supervision. If the child has recurrent urinary tract infections, imaging tests such as ultrasound of the urinary tract are needed to exclude triggering factors such as urinary tract malformations. In addition to the application of antibiotic treatment, usually pay attention to clean the vulva, timely change of diapers or underwear, more water for young children to increase the frequency of urination, these measures are also helpful in the treatment of urinary tract infection.
