This study establishes age-adjusted reference values for bladder diary measurements, crucial for diagnosing nocturia. Night urine production rate, adjusted for age and volume, is identified as the most reliable indicator.

Area of Science:

  • Urology
  • Gerontology
  • Physiology

Background:

  • Bladder diary measurements are essential for assessing urinary function.
  • Establishing age-adjusted reference values is critical for accurate clinical interpretation of nocturia.

Purpose of the Study:

  • To investigate bladder diary measurements in asymptomatic individuals across different age groups.
  • To develop age-adjusted reference values for daytime and nighttime voiding parameters.
  • To compare relationships between age, voided volume, and urine production.

Main Methods:

  • Collected three-day bladder diaries from 253 participants (161 females, 92 males).
  • Analyzed average voided volume (Vavg), voiding frequency, and urine production measures (volume, rate, ratios).
  • Utilized regression analysis to adjust for age and total volume.

Main Results:

  • Both daytime and nighttime Vavg and frequency increase with voided volume, with a steeper increase at night.
  • Aging correlates with increased frequency, decreased Vavg, decreased daytime production, and increased nighttime production.
  • Age-adjusted regression analysis significantly reduced variability in night production measures.

Conclusions:

  • Regression equations were developed to adjust Vavg, frequency, and production rate for age and volume influences.
  • A table of 95% confidence limits for night urine production and frequency was calculated.
  • Nighttime/24-hour production rate emerged as the least variable and potentially most efficacious measure for detecting nocturnal polyuria.
