    Elderly men often experience bladder issues like detrusor hyperreflexia, characterized by involuntary bladder contractions. This study suggests age-related obstruction and nervous system changes contribute to these common urinary problems.

    Area of Science:

    • Urology
    • Gerontology
    • Neuroscience

    Background:

    • Age-related changes in bladder function are common in elderly men.
    • Detrusor hyperreflexia, an overactive bladder condition, affects a significant portion of this demographic.
    • Understanding the etiology of these changes is crucial for effective management.

    Purpose of the Study:

    • To investigate bladder function in healthy elderly males.
    • To identify the prevalence of detrusor hyperreflexia in this population.
    • To explore potential etiological factors contributing to observed bladder dysfunction.

    Main Methods:

    • Cystometry, uroflowmetry, and voiding cystourethrography were employed.
    • A cohort of 20 healthy elderly male volunteers participated.

  • Data analysis focused on bladder pressures, flow rates, and neurological findings.

    • Main Results:

    • 53% of participants exhibited detrusor hyperreflexia.
    • Reduced urinary flow rates and elevated maximal intravesical pressures were observed.
    • No direct correlation was found between flow rate/pressure and detrusor hyperreflexia presence.

    Conclusions:

    • Detrusor hyperreflexia is highly prevalent in elderly men.
    • Incipient infravesical obstruction and subclinical neurological impairment are likely etiological factors.
    • These findings highlight the multifactorial nature of age-related bladder dysfunction.
