Nocturia: morbidity and management in adults.

Nocturia is an increasingly prevalent and bothersome urinary symptom associated with considerable impact and morbidity in later life. Nocturnal frequency is associated with a number of underlying pathologies, both related and unrelated to the lower urinary tract. Following careful assessment, diagnosis and management, the condition is amenable to amelioration, if not complete cure in the majority of cases. This paper outlines the epidemiology, underlying pathophysiology and diseases associated with nocturia and reviews current treatment strategies.
