Susceptibility to UTI may be increased by any of the following factors:

  • Alteration of the periurethral flora by antibiotic therapy

  • Anatomic anomaly

  • Bowel and bladder dysfunction

  • Constipation

Children who receive antibiotics (eg, amoxicillin, cephalexin) for other infections are at increased risk for UTI. These agents may alter gastrointestinal (GI) and periurethral flora, disturbing the urinary tract's natural defense against colonization by pathogenic bacteria.
