Painful urination, new urgency, frequent urination, wetting after a child has been dry, blood in the urine, or fever without a clear cause can need prompt evaluation. These symptoms can have several causes; a urine test is often needed to know whether a urinary tract infection (UTI) is present.

Urgent Warning Signs - Check This First

When in doubt about a life-threatening emergency, call 911.

CALL 911 NOW

  • Your child is not breathing normally, turns blue or gray, is limp or unresponsive, cannot be awakened, or you believe your child is in immediate danger

  • Your child has signs of severe illness or shock, such as confusion, collapse, cold or mottled skin, extreme weakness, or inability to stay awake

GET EMERGENCY MEDICAL CARE NOW

  • Your child cannot pass urine, can pass only a few drops with significant pain, or has a swollen lower belly with trouble urinating

  • There is severe back, side, lower-belly, or genital pain with vomiting, fever, marked weakness, or the child looks very ill

  • There is blood in the urine with severe pain, a serious genital injury, or an inability to urinate

  • There is sudden severe testicle or scrotum pain, swelling, redness, or a high-riding testicle, with or without belly pain, nausea, or vomiting. Go directly to an emergency department

  • A child has fever with extreme sleepiness, confusion, persistent vomiting, trouble breathing, or another severe symptom. See Fever and Illness: When to Seek Care

CONTACT YOUR CHILD'S HEALTHCARE PROFESSIONAL TODAY

  • A baby younger than 3 months has a rectal temperature of 100.4 F (38.0 C) or higher. This needs prompt evaluation even if urinary symptoms are not obvious

  • A baby or child younger than 2 years has fever without a clear source, poor feeding, vomiting, unusual fussiness, or unusual sleepiness. Young children may have few recognizable UTI symptoms

  • There is burning, pain, or crying with urination; frequent or urgent urination; new daytime or nighttime wetting after a child has been dry; lower-belly pain; or new strong-smelling, cloudy, or bloody urine

  • There is fever with back or side pain, chills, nausea, vomiting, or general illness; these symptoms can occur with a kidney infection

  • The symptoms began after a straddle injury, bicycle-bar injury, sexual contact, a new medicine, or a possible irritant, or there is redness, swelling, discharge, or a rash on the genitals

  • Your child has diabetes, kidney disease, immune suppression, a known urinary-tract condition, prior urinary surgery, a history of recurrent UTIs, or symptoms are returning after treatment

What Urinary Symptoms Can Mean

A UTI is one possible cause, but symptoms alone cannot confirm it. Genital irritation, constipation, concentrated urine, a viral illness, a kidney stone, an injury, and sexually transmitted infections in adolescents are among other possible causes. A clinician may need a properly collected urine sample before deciding on treatment.

  • In infants and young children, fever may be the only obvious sign of a UTI. Poor feeding, vomiting, diarrhea, fussiness, or decreased energy can also occur

  • In older children, common symptoms can include burning or pain with urination, frequent or urgent urination, lower-belly discomfort, new wetting, or blood in the urine

  • Fever, chills, vomiting, back or side pain, and a child who looks generally ill can be signs that infection may involve the kidneys and need prompt assessment

  • Constipation and holding urine can contribute to bladder and bowel symptoms. Mention stool pattern and constipation when you call

Safe Home Steps While You Arrange Care

Home measures do not replace an evaluation when a UTI or another significant cause is possible.

  • Offer regular fluids if your child is awake and able to drink. Encourage toilet-trained children to use the bathroom when they feel the need and to take time to empty the bladder

  • Do not use leftover antibiotics, someone else's medicine, or over-the-counter urinary products unless a healthcare professional has specifically recommended them for your child

  • Avoid forcing a child to hold urine. Address constipation with the child's healthcare professional, since bowel and bladder symptoms commonly affect each other

  • For skin irritation, use gentle hygiene and avoid scented products or other possible irritants. Do not force back the foreskin of an uncircumcised child

  • If a clinician starts antibiotics for a confirmed infection, give them exactly as directed and contact the clinician if symptoms worsen, vomiting prevents doses, or your child is not improving as expected

What to Have Ready When You Call

  • Your child's age, medical conditions, previous UTIs or urinary problems, and current medicines

  • Temperature and how it was measured; when symptoms started; whether your child is drinking, vomiting, and urinating normally

  • The specific urinary symptoms: pain, frequency, urgency, new wetting, lower-belly or back pain, urine color, and any blood

  • Bowel pattern and constipation; recent injury or new products; and any genital pain, swelling, rash, discharge, or possible sexual exposure in an adolescent
