nocturnal enuresis
Pronunciation: en-yoo-REE-sis
Involuntary nighttime urination in children beyond the expected age of bladder control.
Full Definition
Nocturnal enuresis, commonly known as bedwetting, is the involuntary passage of urine during sleep in children who are chronologically and developmentally expected to maintain bladder control. It affects approximately 15% of 5-year-olds and can be primary (never achieved consistent dryness) or secondary (recurrence after a dry period). Primary nocturnal enuresis is often related to delayed maturation of bladder control mechanisms, deep sleep patterns, or hormonal factors. Treatment options include behavioral interventions, alarm therapy, and medications such as desmopressin.
Usage
Usage note: Distinguish from diurnal (daytime) enuresis in documentation.
