Bed-Wetting (Enuresis)

Definition

Enuresis (bed-wetting) is the term used for the involuntary passage of urine during sleep. We consider it normal until at least age 6.

Causes

Most of these children have inherited small bladders, which cannot hold all the urine produced in a night. In addition, they are deep sleepers who don't awaken to the signal of a full bladder. The kidneys are normal. Physical causes are very rare, and your physician can easily detect them. Emotional problems do not cause enuresis, but they can occur if it is mishandled.

Measure your child's bladder size to help you understand how important it is for him to get up at night. Do this by having your child hold his urine as long as possible on at least three occasions. Have your child urinate into a container each time. Measure the amount of urine in ounces. The largest of the three measurements can be considered your child's bladder capacity. The normal capacity for children is 1 or more ounces per year of age.

Expected Course

Most children who are bed-wetting overcome the problem between ages 6 and 10. Even without treatment, all children eventually get over it. Therefore, treatments that might have harmful complications should not be used. On the other hand, treatments without side effects can be started as soon as your child has had complete bladder control during the daytime for 6 to 12 months.
