Variations of Nighttime and Daytime Bladder Capacity in Patients with Nocturia: Implication for Diagnosis and Treatment

Abstract

Patients with nocturnal polyuria have a different bladder capacity in the day and the night. Severe nocturia (3 or more episodes per night) predicts the presence of nocturnal polyuria and reduced bladder capacity. Our data suggest that in patients with severe nocturia those 2 conditions should be considered and managed.
