Urinary tract function changes with age, even in healthy individuals. Symptoms like nocturia increase, and urodynamic measures such as maximum flow rate decline in both sexes.

Area of Science:

  • Gerontology
  • Urology
  • Physiology

Background:

  • Lower urinary tract function can change with age.
  • Age-related alterations may occur even in asymptomatic individuals.

Purpose of the Study:

  • To investigate age-related changes in lower urinary tract function.
  • To assess changes in symptomatology and urodynamics in aging adults.

Main Methods:

  • Symptom study: Questionnaire administered to 168 males and 101 females over 30.
  • Urodynamic study: Assessed 65 males and 51 females with low symptom scores.
  • Statistical analysis to correlate age with urinary symptoms and urodynamic parameters.

Main Results:

  • Urinary symptom prevalence increased with age, with nocturia significantly rising in those over 70.

  • Maximum flow rate decreased significantly with age in both males and females.
  • Maximum detrusor pressure decreased in females, while residual urine increased in males.

    • Conclusions:

    • Urinary symptoms and urodynamic variables can change with age, even in subjects considered 'normal'.
    • Findings suggest careful interpretation of these parameters in elderly individuals.
    • Age-related changes in lower urinary tract function are evident across both symptomatic and asymptomatic populations.
