UTI in Children

A urinary tract infection, or UTI, can affect the bladder or kidneys. Symptoms vary with age and may include fever, pain while urinating, frequent urination, abdominal or back pain, vomiting or unexplained illness in a young child. Correct urine collection and culture are important before labelling recurrent infection.

Common signs

What parents may notice

  • Pain or crying during urination
  • Frequent or urgent urination
  • Fever without an obvious cause
  • Abdominal or back pain
  • New wetting accidents
  • Strong-smelling or cloudy urine
  • Poor feeding or vomiting in a young child
Possible reasons

What can cause it?

Bacteria can enter the urinary tract. Recurrent infection may be associated with bladder habits, constipation, urinary tract anatomy or other factors. The urine-collection method matters because contamination can produce a misleading result.

Questions parents ask

The real questions, answered.

Not what we wish you'd ask. What you're actually thinking when you find this page.

Book a consultation
Can a child have a UTI without pain?

Yes. Young children may present only with fever, poor feeding, vomiting or irritability.

Why is urine culture important?

Culture helps confirm infection and identify which antibiotic is likely to work.

Can constipation contribute to UTIs?

Yes. Constipation can affect bladder emptying and is often reviewed in children with recurrent infection.

Will every child need an ultrasound?

Imaging depends on age, fever, recurrence and the clinical history.

How can recurrence be reduced?

Treatment may include regular toileting, hydration, constipation care and other measures tailored to the child.

Persistent symptoms deserve a clear next step.
