Dysuria: Infection vs. Chemical (Child)

Choose a preferred language

Location of ureter, bladder, and urethra in female child.

The urethra is the channel that passes urine from the bladder. In a girl, the opening of the urethra is above the vagina. In a boy, it's at the tip of the penis. Dysuria is having pain or a burning feeling in the urethra when peeing. Your child may get medicine to help ease pain.

Dysuria can be caused by anything that irritates or inflames the urethra. Examples include:

  • Chemical irritation. This is the most common cause of dysuria in young children. Soaps, bubble baths, or skin lotions can get inside the urethra. Symptoms will get better in 1 to 3 days after the last exposure.

  • Certain foods. Caffeine is the most common. High-potassium and hot, spicy foods can also cause irritation.

  • Bladder infection. A urine test can show this. The health care provider will treat a bacterial bladder infection with antibiotics. Make sure your child takes all of the medicine. They need to take it even when they start feeling better. Symptoms of a UTI usually go away within 24 to 72 hours of starting treatment. Children can also get a viral infection of the bladder. This will get better with time. You don't need antibiotics for a viral infection.

  • Inflammation in the outer vaginal area (rash or vaginal infection). Your child may be given a cream for this.

  • Vaginal infection. This may cause vaginal discharge and dysuria. A culture can diagnose it. Antibiotics may be needed to treat the infection.

  • Labial adhesions. These are a common cause of dysuria in young girls. Parts of the labia are attached together. A small tear can cause pain. The tear will get better on its own. But an estrogen cream can be used to help treat the adhesions.

  • Minor injury. These may result from from activities or self-exploration.

  • Medicines. Review all your child's medicines with your provider.

  • Bladder catheter. Having one for a long time can cause dysuria.

Other causes include dehydration and structural abnormalities of the urinary system.

In rare cases, dysuria is a result of genital injury from sexual abuse. If you have concerns about possible sexual abuse, contact your child's provider right away. Or call the National Child Abuse Hotline at 800-4-A-CHILD (800-422-4453) to get help.


How is dysuria diagnosed?

Your provider will ask about your child's medical history and do a physical exam. Your child may have test, including:

  • Urinalysis. The urine is checked for bacteria and other signs of infection. The urine is sent to a lab for a culture. This shows what kind of bacteria is in the urine. It can take 1 to 3 days to get the results back. The provider may think your child has a urinary tract infection (UTI). In that case they will likely start treatment before the lab results come back.

  • Ultrasonography. This can show if a child's urinary system did not form correctly before birth.


Home care

These tips will help you care for your child at home:

  • Wash the genitals gently with a washcloth and mild soapy water. Make sure soap doesn't get inside the urethra. Dry the area well.

  • If you think bubble bath soap caused the reaction, stop using bubble baths.

  • Use over-the-counter diaper creams to help with irritation in the genital area.

  • Change soiled diapers right away. Keep the genital region clean and dry.

  • Encourage your child to drink water. Have them stay away from foods and drinks that can cause bladder infections.

  • Make sure your child wipes from front to back after using the toilet. Wipe your baby from front to back during diaper changes.

  • Have your child wear loose-fitting underpants and clothing.

  • Regular urination and regular bowel movements may help reduce the risk of UTIs.

  • Soaking in warm water without soap for about 10 minutes can help ease pain. Repeat as needed.


Follow-up care

Follow up with your child's provider, or as advised. If the provider took a culture specimen, call for the result as advised.


When to contact your child's doctor

Contact your child's provider right away if:

  • Your child's symptoms don't go away after 3 days, or new symptoms appear.

  • Your child has a fever of 101°F (38.3°C) or higher, or as advised by the provider.

  • Your child can't pee due to pain.

  • You see increased redness or rash in the genital area.

  • There's discharge or bloody drainage from the penis or vagina.
