Abstract

OBJECTIVES: To determine if nocturnal polyuria in geriatric patients with nocturia and nocturnal incontinence is associated with elevated plasma atrial natriuretic peptide (ANP) levels. DESIGN: Case series. SETTING: Four nursing homes and two board and care facilities. PARTICIPANTS: Fifty-four nursing home residents and 26 board and care residents with a mean age of 86. MEASUREMENTS: Daytime (7:00 a.m. to 7:00 p.m.) and nighttime (7:00 p.m. to 7:00 a.m.) urine volumes of incontinent nursing home residents were measured over 3 days and 3 nights by reweighing preweighed adults diapers and toileting inserts emptied by research staff for the board and care group. Blood was drawn in the early morning (5:00 a.m. to 7:00 a.m.) before subjects arose and in the evening after an hour of lying in bed (8:00 p.m. to 11:00 p.m.), and plasma ANP levels were determined by radioimmunoassay. RESULTS: Forty-nine (61%) of the subjects had nocturnal polyuria as defined by night/total urine volume ratios ≥ 50%. There was no significant difference between those with night/total ratios ≥ 50% versus
