Urinary Tract Infection

What is a Urinary Tract Infection (UTI)?

A UTI is a bacterial bladder infection, also known as cystitis. It can happen anywhere along the urinary tract, including the bladder, kidneys and greeters. In boys, Otis is most common before their first birthday. In young girls, UTIs are most common around age 3, the time of toilet training. Cystitis in children can be promoted by abnormalities in the urinary tract. Therefore, children with cystitis, especially those under age 5, deserve special follow-up to prevent later kidney damage. 


Symptoms include:

  • Frequent or urgent need to urinate
  • Pain or burning with urination
  • Need to urinate at night
  • Cloudy urine, or blood in the urine
  • Strong odor
  • A depressed mood, feelings of hopelessness and crying spells.
  • NOTE: Young children may only have a fever.


Tests usually include taking a urine sample/culture. Many children with a UTI need special imaging studies to determine why they got a urinary tract infection. Many have anatomical abnormalities that predispose them to infections. Repeated urinary tract infections in children can cause serious problems, including kidney damage. 


Children with cystitis should be treated promptly with antibiotics to protect their developing kidneys.
