Analysis of Nocturia Determinants Using a Novel Portable Urine-Measuring Device

Area of Science:

• Urology
• Gerontology
• Biomedical Engineering

Background:

• Nocturia, or nighttime urination, affects older adults and can impact quality of life.
• Understanding the factors contributing to nocturia is crucial for developing effective management strategies.

Purpose of the Study:

• To explore the correlation between nocturia and various urine parameters measured by a new portable device.
• To assess the utility of this device in guiding nocturia management.

Main Methods:

• Thirty-three older men with nocturia were enrolled.
• A novel portable device measured urine volume, salt content, temperature, and urination speed over 24 hours and two nights.
• Correlation analyses were performed to identify relationships between nocturia and measured parameters.

Main Results:

• Nocturnal urination frequency positively correlated with nocturnal urine volume (r=0.65) and salt content (r=0.57).
• Frequency negatively correlated with nocturnal urine temperature (r=-0.37).
• No significant correlation was found between nocturia and 24-hour urine volume or salt content, nor with morning blood pressure.

Conclusions:

• Nocturnal urine volume, salt content, and temperature are key factors associated with nocturia.
• The portable urine-measuring device shows promise for guiding nocturia reduction strategies by monitoring these parameters.
