Urine infection (UTI) in children
Pokenga ara mimi ki ngā tamariki
Urinary tract infections (UTIs) are an infection in your wee (urine).
They can affect any part of your urinary tract, but usually start in your bladder. They are usually caused by germs (bacteria) that enter the urinary tract. They get in through the tube that carries wee from your bladder out of your body (urethra).
UTIs are common in tamariki (children). While they are not usually serious, it is important to diagnose and treat them quickly to reduce the risk of complications.
Symptoms of a UTI in children
It can be hard to tell if your tamaiti (child) has a UTI as symptoms can be vague. Tamariki may have difficulty communicating how they feel. Common symptoms include:
- pain or burning feeling when weeing
- needing to wee more often than usual
- needing to wee during the night
- bedwetting, if previously dry
- wetting during the day when previously dry
- smelly wee
- cloudy wee
- blood in the wee
- pain in the lower part of the tummy, side or lower back
- feeling generally unwell often with loss of appetite.
Diagnosing a UTI in children
Your general practice team will usually ask questions about the symptoms your tamaiti has. They will also examine them and ask for a sample of wee to test.
Treating UTIs in children
Most UTIs in tamariki can be treated with antibiotics. Treatment is usually for 5 days or longer.
It is very important to finish the whole course of antibiotics to prevent the infection coming back.
Your general practice team may refer your tamaiti to a specialist in children’s health (paediatrician). They will do this if your tamaiti is very unwell, needs further tests or does not respond to treatment.
Getting help for your child with a UTI
If you think your tamaiti could have a UTI, contact your general practice team as soon as possible.
Go back to your general practice team if your tamaiti is not showing any signs of improvement within a day or 2 after starting antibiotics.
