Health Information For Parents
Urinary tract infections (UTIs) are common in kids. They happen when bacteria (germs) get into the bladder or kidneys.
A baby with a UTI may have a fever, throw up, or be fussy. Older kids may have a fever, have pain when peeing, need to pee a lot, or have lower belly pain.
Kids with UTIs need to see a doctor. These infections won’t get better on their own. UTIs are easy to treat and usually clear up in a week or so.
Taking antibiotics kills the germs and helps kids get well again. To be sure antibiotics work, you must give all the prescribed doses — even when your child starts feeling better.
Most UTIs happen in the lower part of the urinary tract — the urethra and bladder. This type of UTI is called cystitis. A child with cystitis may have:
An infection that travels up the ureters to the kidneys is called pyelonephritis and is usually more serious. It causes many of these same symptoms, but the child often looks sicker and is more likely to have a fever (sometimes with shaking chills), pain in the side or back, severe tiredness, or vomiting.
UTIs are much more common in girls because a girl’s urethra is shorter and closer to the anus. Uncircumcised boys younger than 1 year also have a slightly higher risk for a UTI.
Other risk factors for a UTI include:
UTIs are easy to treat, but it’s important to catch them early. Undiagnosed or untreated UTIs can lead to kidney damage.
To diagnose a UTI, health care providers ask questions about what’s going on, do a physical exam, and take a sample of pee for testing.
How a sample is taken depends on a child’s age. Older kids might simply need to pee into a sterile cup. For younger children in diapers, a catheter is usually preferred. This is when a thin tube is inserted into the urethra up to the bladder to get a “clean” urine sample.
The sample may be used for a urinalysis (a test that microscopically 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 treatment.
UTIs are treated with antibiotics. After several days of antibiotics, your doctor may repeat the urine tests to confirm that the infection is gone. It’s important to make sure of this because an incompletely treated UTI can come back or spread.
If a child has severe pain when peeing, the doctor may also prescribe medicine that numbs the lining of the urinary tract. (This medication temporarily causes the pee to turn orange.)
Give prescribed antibiotics on schedule for as many days as your doctor directs. Keep track of your child’s trips to the bathroom, and ask your child about symptoms like pain or burning during peeing. These symptoms should improve within 2 to 3 days after antibiotics are started.
Encourage your child to drink plenty of fluids, but avoid beverages containing caffeine, such as soda and iced tea.
Kids with a more severe infection may need treatment in a hospital so they can get antibiotics by injection or intravenously (delivered through a vein right into the bloodstream).
This might happen if:
Kids with VUR will be watched closely by the doctor. VUR might be treated with medicines or, less commonly, surgery. Most kids outgrow mild forms of VUR, but some can develop kidney damage or kidney failure later in life.
In infants and toddlers, frequent diaper changes can help prevent the spread of bacteria that cause UTIs. When kids are potty trained, it’s important to teach them good hygiene. Girls should know to wipe from front to rear — not rear to front — to prevent germs from spreading from the rectum to the urethra.
School-age girls should avoid bubble baths and strong soaps that might cause irritation, and they should wear cotton underwear instead of nylon because it’s less likely to encourage bacterial growth.
All kids should be taught not to “hold it” when they have to go because pee that stays in the bladder gives bacteria a good place to grow. Kids should drink plenty of fluids and avoid caffeine, which can irritate the bladder.
Most UTIs are cured within a week with treatment.
Call your doctor immediately if your child has an unexplained fever with shaking chills, especially if there’s also back pain or any type of pain when peeing.
Also call if your child has any of the following:
Call the doctor if your infant has a fever, feeds poorly, vomits repeatedly, or seems unusually irritable.
Recurrent urinary tract infections can cause kidney damage if left untreated, especially in kids under age 6. Here’s how to recognize the symptom of UTIs and get help for your child.
When it hurts to pee, a urinary tract infection (UTI) is usually to blame. But there are other causes. Here’s what to do.
Is your child having a urine culture or urinalysis performed? Find out why urine tests are performed, and what to expect when the doctor orders them.
Automated dipstick urinalysis results may point to a urinary tract infection (UTI) or injury, kidney disease, or diabetes.
The bean-shaped kidneys, each about the size of a child’s fist, are essential to our health. Their most important role is to filter blood and produce urine.
Bedwetting is an issue that millions of families face every night. Most of the time it’s not a sign of any deeper medical or emotional issues and kids eventually grow out of it.
A renal ultrasound makes images of your child’s kidneys, ureters, and bladder. Doctors may order this test if they suspect kidney damage, cysts, tumors, kidney stones, or complications from urinary tract infections.
A VCUG can help evaluate the bladder’s size and shape, and look for problems, such as a blockage. It can also show whether pee is moving in the right direction.
A urinary tract infection (UTI) is one of the most common reasons that teens visit a doctor. Learn about the symptoms of UTIs, how they’re treated, and more in this article.

Sometimes, the kidneys can’t do their job properly. In teens, kidney disease is usually due to infections, structural issues, glomerulonephritis, or nephrotic syndrome.
The kidneys perform several functions that are essential to health, the most important of which are to filter blood and produce urine.

Bedwetting can be embarrassing and upsetting for teens, but there are effective ways to correct the problem and scientists are constantly developing new treatments.
Antibiotics are powerful medicines that can help kids feel better — but only when they have certain illnesses. Find out if an antibiotic is right for your child.
