Auscultation of urinary flow

W E Bradley, B P Brockway, G W Timm

    The Journal of Urology
    |July 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Turbulence during male urination at the bladder neck creates a sound transmitted to the perineum. This study investigates the acoustic properties of healthy male urinary flow.

    Area of Science:

    • Urology
    • Bioacoustics
    • Human Physiology

    Background:

    • Urinary flow dynamics are complex and influenced by anatomical structures.
    • The bladder neck is a critical region for regulating urine expulsion.
    • Acoustic phenomena associated with physiological processes are not fully understood.

    Purpose of the Study:

    • To investigate the generation and transmission of sound during male urination.
    • To characterize the acoustic properties associated with bladder neck turbulence.
    • To establish a baseline for sound production in healthy male urinary flow.

    Main Methods:

    • Utilized non-invasive acoustic measurement techniques.
    • Recorded sound transmission from the perineum during micturition.

    Related Experiment Videos

  • Analyzed acoustic signals for characteristics related to flow dynamics.

    • Main Results:

    • Confirmed the association between urinary flow turbulence at the bladder neck and sound production.
    • Identified sound transmission to the perineal region in healthy males.
    • Characterized specific acoustic signatures linked to bladder neck turbulence.

    Conclusions:

    • The sound produced during male urination originates from turbulence at the bladder neck.
    • Perineal sound transmission provides a measurable indicator of urinary flow characteristics.
    • Findings contribute to understanding the biomechanics and acoustics of the lower urinary tract.
