Analysis of changes in the pathophysiology of nocturia according to the number of nocturia episode, age, and gender using frequency volume charts: A retrospective observational study.

ABSTRACT:

Purpose

To evaluate the pathophysiology of nocturia based on the frequency volume chart, and determine the risk factors for nocturia occurring ≥2 times per night.

Materials and methods

In this retrospective study, we reviewed 311 patients with complaints of nocturia from January 2017 to February 2019 at our institution. Nocturnal polyuria (NP) and global polyuria (GP) were defined as NP index >0.35 regardless of age and 24 h urine volume >2.5 L/day, respectively. Decreased bladder capacity (dBC) was when the maximal voided volume was <325 mL. Decreased nocturnal bladder capacity (dNBC) was defined as nocturnal bladder capacity index >0.

Results

In total, 273 patients were included in the primary analyses. Of 802 days from 273 frequency volume charts, the median number
