A urinary tract infection (UTI) is an infection of any part of the urinary system (including the kidneys and bladder). Urinary tract infections are more common in girls than in boys.
UTIs are usually caused by bacteria which infect the urinary tract. An infection can occur anywhere along the urinary tract, but the lower part - the urethra and bladder - is most commonly involved. This is called cystitis. If the infection travels up the ureters to the kidneys, it's called pyelonephritis and it's generally more serious. Although bacteria are not normally found in the urine, they can easily enter the urinary tract from the skin around the anus. Intestinal bacteria E. coli is the most frequent cause of urinary tract infection.

If your child has the abovementioned symptoms,
After performing a physical exam, the doctor may take a urine sample to check for and identify bacteria causing the infection.The urine sample may be used for a urinalysis (a test that checks the urine for germs or pus) or a urine culture (which attempts to grow and identify bacteria in a laboratory). Knowing what bacteria are causing the infection can help your doctor choose the best medication to treat it.
Urinary tract infections are treated with antibiotics. The type of antibiotic used and how long it must be taken will depend on the type and severity of bacteria causing the infection.After several days of antibiotics, your doctor may repeat the urine tests to check if the infection is gone. An incompletely treated UTI can recur or spread.
