Urinary Tract Infection (UTI) in Babies and Children: Symptoms, Diagnosis and Treatment
🎯 "My baby has a fever, but he doesn't have a runny nose or cough. His doctor asked for a urine test. Why could this be?"
Urinary tract infections (UTI) are one of the most common infections in infancy and childhood. Especially in the first 2 years of age, the only symptom may be fever and delayed diagnosis may cause kidney damage.
In this article, you can find all you need to know about the symptoms of UTI, how it is diagnosed, when it can be dangerous, and the treatment process.
📌 What is UTI?
Urinary tract infection; It is an infection that can involve the bladder (cystitis), ureters, urinary tract or kidneys (pyelonephritis).
Urine is a sterile liquid, but in some cases, germs reach the urinary tract and cause infection.
UTI specifically:
• It is more common in girls
• It can also cause serious infections in newborn male babies.
🔍 Symptoms May Vary Depending on Age
👶 In babies:
• Unexplained fever (above 38°C)
• Restlessness
• Malnutrition, decreased absorption
• Bad smelling diaper
• Urine that is darker than yellow and has a strong odor
• Sometimes vomiting or diarrhea
🧒 In older children:
• Frequent urination
• Burning when urinating, crying
• Pain in the lower abdomen
• Bedwetting during the day, sudden bedwetting at night
• Blood in urine
🧪 How to Diagnose?
The most important step for the diagnosis of UTI is urinalysis and urine culture.
✅ How to collect urine?
• For diapered babies: with a sterile bag (for preliminary screening), if in doubt, with a catheter.
• In a child who is toilet trained: midstream urine can be collected.
• Urine culture: shows which microbe is causing the infection
• If necessary: complete blood count, CRP, kidney ultrasound
💊 How is Treatment Done?
Treatment is planned according to the child's age, general condition and location of infection:
• Oral antibiotic treatment for mild infections
• Intravenous antibiotics (hospitalization) in children with fever and poor general condition.
• Usually 7-10 days of treatment is sufficient
• Fever subsides within 24-48 hours after starting treatment
🔁 Why Does UTI Recur?
UTI may recur in some children. In recurring cases:
• Urinary tract reflux (VUR): urine leaking back into the kidneys
• Congenital kidney and bladder structural disorders
• Constipation and hygiene problems
• Family history of UTI
🩺 When to Consult a Doctor?
In the following cases, a pediatrician should be consulted without delay:
• Unexplained fever over 38°C
• Bad smell in urine
• Crying or restlessness while urinating
• Seeing blood in the urine
• Day or night bedwetting (especially if it has just started)
• If there is a history of UTI before
💡 Suggestions for Families
✅ The only cause of fever in babies and children is not always apparent — urinary tract infection should be kept in mind
✅ Hygiene is very important when changing diapers
✅ Girls should be taught the habit of wiping from front to back.
✅ Constipation should be prevented
✅ Consuming plenty of fluids should be encouraged
✅ Day and night toilet habits should be monitored
📌 Result
UTI in babies and children is an infection that is often unnoticed but can be completely treated with early diagnosis.
If the cause of fever is not clear, the urinary tract should also be evaluated, as it may cause permanent damage to the kidneys if diagnosis and treatment are delayed.
