    Area of Science:

    • Veterinary Medicine
    • Urology
    • Animal Physiology

    Background:

    • Urinary incontinence is a clinical challenge in mares.
    • Objective diagnostic methods for equine urinary incontinence are limited.
    • Urethral pressure profilometry is a potential tool for assessment.

    Purpose of the Study:

    • To develop and validate a technique for recording urethral pressure profiles (UPP) in mares.
    • To compare UPP parameters between clinically normal mares and those with urinary incontinence.
    • To establish the reliability of UPP for evaluating urethral function in mares.

    Main Methods:

    • Developed a simple and reliable technique for UPP recording in mares.
    • Obtained UPP data from 12 clinically normal mares.

  • Obtained UPP data from 3 mares diagnosed with urinary incontinence.
  • Measured intravesicular pressure and maximal urethral closure pressure.

    • Main Results:

    • The mean maximal urethral closure pressure was significantly lower in mares with urinary incontinence compared to normal mares (P <= 0.001).
    • The UPP technique proved simple and reliable for objective evaluation.
    • Individual UPP variations were noted, highlighting the need for comparative analysis.

    Conclusions:

    • The developed UPP technique is a valuable, objective tool for diagnosing urinary incontinence in mares.
    • Reduced maximal urethral closure pressure is a key indicator of urinary incontinence in this species.
    • This method facilitates a better understanding of urethral function and dysfunction in mares.
