    Area of Science:

    • Urology
    • Medical Imaging
    • Functional Anatomy

    Background:

    • Conventional urethral pressure profile studies offer limited anatomical detail.
    • Accurate assessment of urethral function is crucial for diagnosing and managing conditions like prostatic hypertrophy.
    • Three-dimensional imaging can enhance understanding of complex anatomical structures and their function.

    Purpose of the Study:

    • To introduce a new tomographic method for recording urethral pressure profiles.
    • To enable three-dimensional delineation of urethral functional morphology.
    • To assess the continence mechanism and external urethral sphincter function, particularly in patients with prostatic hypertrophy.

    Main Methods:

    • Development of a novel examination system for tomographic urethral pressure profile recording.

    Related Experiment Videos

  • Recording pressure profiles from anterior, right, posterior, and left urethral walls.
  • Application of urethral pressure tomography in patients diagnosed with prostatic hypertrophy.

    • Main Results:

    • The devised system provides a three-dimensional representation of urethral functional morphology.
    • The method is comparable in time and effort to conventional studies and is non-painful.
    • Stereographic depiction of the bladder neck continence mechanism and external urethral sphincter function was achieved.
    • The degree of urethral oppression was successfully assessed in patients with prostatic hypertrophy.

    Conclusions:

    • The new tomographic urethral pressure profile method offers a comprehensive 3D view of urethral function.
    • This technique is efficient, non-invasive, and provides valuable insights into continence mechanisms.
    • Urethral pressure tomography is a promising tool for evaluating patients with prostatic hypertrophy and related conditions.
