Purpose: We applied the International Continence Society Guidelines and categorized men and women with nocturia 2 or more times a night in pathophysiological groups based on selected lower urinary tract symptoms, clinical examination, frequency volume charts and urodynamics, and categorized the most likely pathophysiological causes of nocturia.Materials and Methods: Participants were randomly selected among respondents in a population study of 4,000 individuals 60 to 80 years old living in Copenhagen County. Nocturia was assessed using the new and validated Nocturia, Nocturnal Enuresis, and Sleep-interruption Questionnaire. Nocturic (2 or more voids) or control (less than 1 void) status was assessed by a 3-day frequency volume chart.
