Nocturia in women

Nocturia, the complaint of waking at night to void, is a bothersome condition known to affect Quality of Life. In addition sleep deprivation is also known to affect daytime functioning and productivity. Whilst recently recognised as a discrete clinical entity nocturia is also a symptom of those women complaining of Overactive Bladder (OAB) syndrome. The causes of nocturia are multifactorial although in clinical practice nocturia is generally associated with either increased nocturnal urine production, problems related to bladder storage or sleep pattern abnormalities. When evaluating women complaining of nocturia a urinary diary and clinical examination is integral to making the diagnosis prior to commencing treatment. Having excluded and treated any underlying cause behavioural modification, such as moderation of fluid intake or timing of taking anti-diuretic medication, should be considered first line therapy. Should this conservative approach fail then treatment with antimuscarinic agents or desmopressin, a nona-peptide analogue of anti-diuretic hormone (ADH) is often helpful.
