A urinary tract infection (UTI) is an infection anywhere in the urinary tract. The urinary tract includes the kidneys, bladder and urethra (the tube from which urine passes out of the bladder).
UTIs are common in children of all ages, but are especially common in children who are still in nappies.
If your child has a UTI, they may:
Young children with a UTI may not show any of these symptoms, but they are just generally unwell.
A UTI is usually caused by bacteria (germs) getting into the bladder or urethra. The germs most often come from the bowels (gut), or from faeces (poo) that is on the skin and then gets into the urethra.
Testing your child's urine is the only way to know for sure if they have a UTI. UTIs should not go untreated, as the infection can cause further problems with the kidneys. You should take your child to a doctor if they:
The doctor may want to do a urine test. See our fact sheet Urine samples for information on how to collect a urine sample.
A urine sample is usually tested first with a dipstick testing strip, which can help show if there is any sign of infection. If the dipstick test shows that there might be a UTI, then treatment may be started. The final urine test results can take up to 48 hours to be sent back to your doctor.
The main way of treating a UTI is with antibiotics, which can usually be taken by mouth as a tablet or syrup. Children who are very unwell may be admitted to hospital for antibiotics given directly into a vein through a drip (intravenous or IV therapy).
Some children with a UTI may need an ultrasound to look for a problem with the bladder or kidneys. Your doctor will discuss this with you if required.
If your child has been diagnosed with a UTI, you can care for them while they are recovering by:
Most children who are treated for a UTI make a full recovery and have no future problems.
How can I prevent my child getting a UTI?
Good hygiene can help prevent the spread of bacteria from the gut. When girls are wiping their bottom after a poo, they should always wipe front to back (vagina to bottom). Also, being constipated can increase the chance of a child getting a UTI. See your doctor if you think your child is constipated.
Can I give my child cranberry juice to treat a UTI?
Children with UTIs need to be treated by a doctor who will prescribe antibiotics. Cranberry juice is not recommended as a treatment option for children.
