As many as 8 percent of girls and 2 percent of boys will develop a urinary tract infection. Furthermore, young children have a greater risk of kidney damage linked to urinary tract infection than older children or adults. The information below should help you recognize a urinary tract infection in children before it causes serious damage.
What causes urinary tract infections in children?
Normal urine is sterile and contains no bacteria. However, even under normal circumstances bacteria cover the skin and are present in large numbers in the rectal area and within bowel movements. Bacteria may, at times, get into the urinary tract and travel up the urethra into the bladder. When this happens, the bacteria multiply and unless the body gets rid of the bacteria, they can cause infection (urinary tract infection or "UTI."
There are two general types of UTIs—bladder infection and kidney infection. When the infection involves the bladder it can cause inflammation, swelling and pain of the bladder. This is called cystitis. If the bacteria travel upward from the bladder through the ureters and reach and infect the kidneys, the kidney infection is called pyelonephritis. Kidney infections are more serious than bladder infections, and can cause kidney damage especially in young children.
What are the symptoms of urinary tract infections in children?
Most often when there is a urinary tract infection, the linings of the bladder, urethra, ureters, and kidneys become red and irritated. This usually causes painful, frequent urination and children may pass urine with a foul odor. Many children start having urinary accidents, and/or bloody urine. If the kidneys become infected, children often have abdominal or back pain and fever. If your child is an infant or too young to tell you how he or she feels, the signs are likely to be vague and unrelated to the urinary tract. For example, your child may just have a high fever, or be irritable and not eating, or sometimes have only a low-grade fever, loose bowel movements or just not seem healthy. You may notice that the diaper urine "smells bad." If your child has a high temperature and appears sick without another obvious source for his/her discomfort (such as runny nose or ear ache), they should see a doctor. If a kidney infection is not treated promptly, the bacteria may spread to the bloodstream and cause a life-threatening infection or permanent kidney damage.
Older children may complain of pain in the low stomach area or back as well as the need to urinate frequently. Your child may cry when he or she urinates or complain that it hurts to urinate and produce only a few drops of urine. It may be hard for them to control their urine so they may have urinary accidents or bed-wetting. They may also produce urine that smells bad or looks cloudy.
How are urinary tract infections treated in children?
Urinary tract infections are treated with antibiotics. If your doctor thinks your child has a urine infection, they will choose a drug that treats the bacteria most likely to be causing the problem. Sometimes a few days later, after the culture results are finished, the antibiotic drug might be changed to one that is more effective against the particular bacteria found in your child's urine. In addition to antibiotics, you can help your child's body fight the infection by encouraging lots of fluids and very frequent urination.
The specific antibiotic drug, way it is given and number of days that it must be taken may depend, in part, on the type and severity of infection. If your child is very sick and unable to take fluids, the antibiotic may need to be given as shots (injected directly into the bloodstream or muscle) with your child in the hospital; otherwise, oral medicine may be given. The daily treatment schedule your child's doctor recommends will depend upon the specific drug prescribed: it may call for a single dose each day or up to four daily doses. In some cases you will be asked to give your child medicine until further tests are finished.
After a few doses of the antibiotic, your child may appear much improved or even have returned to their normal activities, but often it may take weeks before all symptoms are gone. Even if they are improved, it is important that your child take the antibiotic medicines as prescribed by your doctor and not stop them because just because the symptoms have gone away. Unless urinary tract infections are fully treated, they may return, or your child may get another infection.
