Urinary Tract Infections (UTIs) in Children

Overview

Urinary tract infections occur when bacteria or other germs infect parts of the urinary system, including the bladder, urethra, or kidneys. UTIs are common in children and may affect infants, young children, or older children differently.

Some children experience mild infections affecting the bladder, while others may develop more serious infections involving the kidneys. Symptoms may sometimes be difficult to recognise in younger children and infants.

The focus is on early diagnosis, infection treatment, symptom control, and preventing recurrent infections or long-term kidney complications.

Symptoms

Urinary tract infections may affect urination, comfort, appetite, energy levels, or overall wellbeing. Symptoms may include:

• Pain or burning during urination
• Frequent urination
• Fever
• Abdominal or back pain
• Bedwetting or urinary accidents
• Strong-smelling or cloudy urine
• Poor feeding or irritability in infants
• Vomiting or reduced appetite

Some younger children may only show general symptoms such as fever, irritability, or poor feeding.

Causes & Risk Factors

UTIs develop when bacteria enter and multiply within the urinary system. Risk factors may include:

• Poor hydration
• Constipation
• Holding urine for long periods
• Congenital urinary tract abnormalities
• Previous urinary tract infections
• Poor toilet hygiene

Some children may require additional assessment if infections occur repeatedly.

When to Seek Care

You should seek medical assessment if your child:

• Has pain during urination
• Develops fever with urinary symptoms
• Has recurrent urinary infections
• Experiences abdominal or back pain
• Has changes in urinary habits
• Appears unusually unwell or irritable

• Good hydration
• Regular urination habits
• Good toilet hygiene
• Managing constipation
• Early treatment of urinary symptoms

Diagnostics Used

Urinary investigations may be used to identify infection, assess kidney health, and monitor urinary function. Depending on your child’s needs, the care team may use:

• Routine Urinalysis 
  • Urine testing Urine culture
• Routine Urinalysis & Urine Bacterial Culture
• CBC
• CRP (C-Reactive Protein)
  • Paediatric monitoring systems

Support Services

Children with recurrent or severe urinary infections may benefit from additional nutritional, developmental, or family support. Support services may include:

• Nutrition and hydration guidance
• Pharmacy support and medication guidance
• Family education and urinary health support
• Referral coordination and follow-up monitoring

This coordinated approach helps support recovery, kidney health, and long-term urinary wellbeing.
