nocturia
Pronunciation: nock-TURE-ee-ah
The need to wake from sleep to urinate one or more times during the night in children who should have achieved nocturnal continence.
Full Definition
A condition characterized by the interruption of sleep by the need to void, occurring in children beyond the expected age of nocturnal continence development (typically after age 5-6 years). Nocturia differs from nocturnal enuresis in that the child awakens to urinate rather than wetting during sleep. Causes include excessive fluid intake before bedtime, bladder dysfunction, sleep disorders, or underlying medical conditions affecting antidiuretic hormone production. Evaluation may include voiding diaries, urinalysis, and assessment of daytime voiding patterns. Management focuses on addressing underlying causes and behavioral modifications.
Usage
Usage note: Distinguish from nocturnal enuresis; nocturia implies awakening to void.
