UTIs in Children: Symptoms, Causes, Treatment, and Prevention Tips

Urinary tract infections (UTIs) are among the most common bacterial infections affecting children. They can involve the bladder, urethra, or kidneys and may occur at any age, from infancy through adolescence. While many UTIs are mild, delayed diagnosis or treatment can allow the infection to spread to the kidneys, increasing the risk of long-term complications. Recognising childhood UTI symptoms early and seeking timely care are essential.

What is Paediatric UTI?

Paediatric UTI (urinary tract infection) can be described as a bacterial infection that occurs within any area of the urinary tract in children. Lower UTIs involve the bladder or urethra and usually cause urinary discomfort. Upper UTIs affect the kidneys (pyelonephritis) and are more serious, often causing fever and back pain. 

The condition is caused by bacteria, such as E. coli, which come from the bowel and get into the urinary tract of the child.

UTI Symptoms in Children

Identifying UTI symptoms in children is not easy since they depend on age.

Symptoms in Infants (Below 2 years old)

Infants may have nonspecific signs, including:

• A fever with no obvious cause

• Difficulty feeding

• Vomiting

• Irritability

• Foul-smelling urine

• Poor weight gain 

• Some infants can develop jaundice

Symptoms in Toddlers

The following symptoms may occur in toddlers:

• Fever

• Pain during urination

• Frequent urination

• Urgency of passing urine

• Urinary accidents despite proper toilet training

• Lower abdominal pain

Symptoms in Older Children

In older children, these signs and symptoms include:

• Burning sensation when urinating

• Feeling a frequent need to urinate

• Urine that is cloudy or contains blood

• Bad odour from the urine

• Back or side pain

• Feeling sick and having chills, which indicates a kidney infection

Causes of UTI in Children

Most UTIs in children are caused by the E. coli bacteria; however, other bacteria can also be responsible. There are various factors that put a child at increased risk of contracting the infection, such as poor toilet hygiene, retaining urine for a long time, constipation, incomplete bladder emptying, dehydration, and malformations of the urinary tract.

Children with vesicoureteral reflux (VUR), a condition wherein urine flows back into the kidneys, are at increased risk of repeated infections. Additionally, girls are more vulnerable due to the shorter length of the urethra, whereas infant boys who are not circumcised have a slightly increased risk during early infancy.

Risk Factors of UTI in Children

There are several risk factors for paediatric UTI that include:

‍

• History of UTIs

• Family history

• Constipation

• Dehydration

• Bathing in a bubble bath or irritating hygiene products

• Abnormalities in the urinary tract

• Neurogenic bladder

• Diabetes (if relevant)

Identification of these risk factors will help in minimising recurrences and management of UTIs.

How Are UTIs Diagnosed in Children?

The diagnosis starts with the patient’s medical history and a physical examination. Urine tests are performed to confirm the diagnosis if there is suspicion of a UTI.

Possible tests:

• Urine dipstick test

• Urinalysis

• Urine culture (the best diagnostic test)

‍

For different ages, urine tests differ in the following way:

• Clean-catch urine sample for toilet-trained children

• Catheter urine sample for infants and young children

• Suprapubic aspiration in selected situations where contamination must be avoided

‍

Some children may also require imaging studies, particularly after recurrent infections or severe UTIs. These may include:

• Kidney and bladder ultrasound

• Voiding cystourethrogram (VCUG), when vesicoureteral reflux is suspected

• DMSA scan in selected cases to assess kidney damage

‍

Imaging tests like kidney and bladder ultrasound may be ordered if recurrent infections or anatomical problems are suspected. In other cases, a VCUG or DMSA scan can be done.

Treatment for UTIs in Children

It is determined by the age of the child and the severity of the infection symptoms, along with whether it affects the kidneys.

This usually entails:

• Antibiotics taken orally for mild infections

• Antibiotics are injected intravenously for more severe infections or for children who cannot take oral medicines

• Compliance with taking the entire antibiotic course, despite the improvement of symptoms

• Use of medicines that help alleviate symptoms

• Ensuring sufficient fluid intake

Rechecking of urine samples in certain cases (repeated infections, etc.)

If promptly treated, the disease does not have any serious consequences.

Tips for Preventing Childhood UTIs

Steps parents can take include:

• Urinate regularly and avoid holding urine 

• Drinking adequate amounts of fluids every day

• Using a front-to-back wiping technique after defecation or urination

• Not keeping children in wet diapers for long periods of time

• Dressing them in comfortable undergarments made of cotton

• Not using harsh cleaning products or giving them bubble baths
