Enuresis (Bedwetting)

About Enuresis

Enuresis is involuntary urination (peeing) beyond the age of anticipated urinary control. It may include nighttime wetting, like bedwetting, and/or daytime wetting. The wetting can occur frequently or rarely. There are possible structural or neurological disorders that can result in a child wetting, but usually involuntary peeing is the result of a functional disorder (a condition where a bodily function is impaired without a structural or anatomical cause).

What causes bedwetting?

Bedwetting is a common problem in kids, especially children under the age of 6 years. In fact, according to the American Academy of Pediatrics, most children do not become fully toilet trained until they are between 2 and 4 years of age. About 13% of 6-year-olds wet the bed, while about 5% of 10-year-olds do.

No one knows for sure what causes bedwetting or why it stops, but it’s usually a natural part of development and not a sign of any deeper medical or emotional issues. Bedwetting often runs in families: kids who wet the bed often have a relative who did, too. If both parents wet the bed when they were young, it's very likely that their child will, but most children grow out of it.

Bedwetting usually goes away by itself, but until it does, it can be embarrassing and uncomfortable for your child. It’s important to be sensitive to your child’s feelings about bedwetting and provide support and positive reinforcement.

When to See a Doctor about Enuresis

Bedwetting that begins abruptly or is accompanied by other symptoms can be a sign of another medical condition, so be sure to call a doctor if your child has any of these:

  • suddenly starts wetting the bed after being consistently dry
    for at least 6 months
  • begins to wet his or her pants during the day
  • starts misbehaving at school or at home
  • complains of a burning sensation or pain when urinating
  • has to urinate frequently
  • is drinking or eating much more than usual
  • has swelling of the feet or ankles
  • is still wetting the bed at age 7 years
Nocturnal Enuresis (Nighttime Wetting)

Wetting at night after the age of 4 years old may be related to a relative immaturity of how the body controls urine production at night. During sleep a hormone (vasopressin) helps reduce urine production and in some children, not enough of this hormone is released at night. Commonly, these children can be very heavy sleepers and not recognize that their bladder is full and they need to wake up.

Diurnal Enuresis (Daytime Wetting)

Wetting that occurs involuntarily during the day may be caused by a voiding dysfunction such as:

  • Overactive Bladder (Urge syndrome) is associated with frequent episodes of urgency and small bladder capacity (found in two-thirds to three- quarters of children with daytime wetting)
  • Dysfunctional Voiding is related to how the bladder muscles work (there may also be an increased risk of urinary tract infections and constipation)
  • Dysfunctional elimination syndrome includes both significant constipation along with involuntary wetting
  • Other conditions like Giggle incontinence (peeing with laughing, sneezing, or coughing) and Vaginal Reflux (urine caught in the vagina) may cause daytime wetting

How is Enuresis treated?

Our medical team will first evaluate your child for conditions like a bladder infection, an anatomical problem, or a neurological disorder. If none are found, then we may consider therapy that includes committing to a home management plan to help monitor your child’s progress and behaviors, as well as keeping a bladder/bowel daily diary. It may take some time to see improvement, but we will be with you and your child every step of the way, providing gentle, compassionate support.

Urine Test: Calcium

What It Is

A urine calcium test is done to determine how much of the mineral calcium is being excreted in the urine by the kidneys.

Why It's Done

A urine test for calcium is often done to:

  • help determine the cause of kidney stones and other kidney diseases
  • detect overactivity or underactivity in the parathyroid glands (glands in the neck that produce hormones that help control the level of calcium in the blood)
  • monitor disorders of the kidney and diseases of calcium metabolism

Results may also point to digestive disorders that interfere with the small intestine's ability to absorb nutrients. The urine calcium test is usually used in combination with other tests to make a specific diagnosis.

Preparation

The doctor might prescribe a special diet with high or low levels of calcium for a few days before the test. Your child might need to temporarily stop taking specific drugs, such as antacids, that affect calcium levels in the urine.

The Procedure

Collecting the specimen should only take a few minutes. Your child will be asked to urinate into a clean sample cup in the doctor's office. If your child isn't potty trained and can't urinate into a cup, a small catheter may need to be inserted into the bladder to obtain the urine specimen.

Alternatively, a urine collection bag with adhesive tape on one end may be used to collect a sample from an infant. You'll clean your baby's genital area and then arrange the bag around the urinary opening. Once the bag is in place, secure it with the attached tape. You can then put a diaper on your baby. Check your baby's collection bag and remove it after your child has urinated, usually within an hour.

After you bring the sample to the lab, technicians will analyze it for calcium content.

What to Expect

Because the test involves normal urination, there shouldn't be any discomfort as long as your child can provide a urine specimen.

Getting the Results

The results of the urine calcium test are usually available in 1-2 days. Your doctor will go over the results with you and explain what they mean. If abnormalities are found, your doctor may may want to do further tests to make a specific diagnosis.

Risks

Infants may occasionally experience skin irritation from the adhesive tape on the collection bag. If a catheter is used to obtain the urine, it may cause temporary discomfort. If you have any questions or concerns about this procedure, talk to your doctor.

Helping Your Child

Urine collections are usually painless. Explaining how the test will be conducted and why it's being done can help ease any fear. Make sure your child understands that there should be no foreign matter, such as toilet paper or hair, in the sample.

If You Have Questions

If you have questions about the urine calcium test, speak with your doctor.
