The nocturnal polyuria index (NP<jats:sub>i<\/jats:sub>) was defined as the ratio of nocturnal and 24\u2009h urine output. Subgroups were defined according to variations in nocturia frequency during the three 24\u2009h\u2010periods of the FVC (fluctuating\/consistent) and to the number of nocturia episodes during a single night (0\/1\/\u22652).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We analyzed 504 24\u2009h\u2010FVC, collected by 168 subjects (58% female) with a median age of 60 (50\u201068) years. Nocturia frequency fluctuated in 69 (41%) subjects. For the same number of nocturnal voids, we found no differences in NP<jats:sub>i<\/jats:sub> and maximum voided volume (MVV) between consistent and fluctuating nocturia frequency. Increasing numbers of nocturnal voids were associated with an increasing NP<jats:sub>i<\/jats:sub> in subjects with fluctuating nocturia, while for consistent nocturia, it was linked to an increase in NP<jats:sub>i<\/jats:sub> and a decrease in MVV. For both subjects with fluctuating and consistent nocturia, increasing nocturia severity was associated with increasing daytime fluid intake.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>For the same number of nocturnal voids, bladder capacity, and NUP were similar between patients with consistent and fluctuating nocturia.
