A Rosin, E Rosin, J Oliver

    American Journal of Veterinary Research

    Summary
    This summary is machine-generated.

    Urethral pressure profiles were measured in normal dogs. Female dogs showed age-related differences in maximum urethral closure pressure, while male dogs had higher pressures than younger females.

    Area of Science:

    • Veterinary Urology
    • Canine Physiology

    Background:

    • Urethral pressure profilometry is crucial for assessing lower urinary tract function.
    • Standardized nomenclature is essential for comparing urethral pressure profile (UPP) data across studies.

    Purpose of the Study:

    • To establish reference values for urethral pressure profiles in healthy dogs.
    • To investigate potential age-related differences in urethral closure pressure in female dogs.

    Main Methods:

    • Urethral pressure profiles were recorded in seven female and six male dogs using a saline-infused catheter.
    • Dogs were immobilized with xylazine, and catheters were withdrawn at a fixed rate.
    • Nomenclature followed International Continence Society recommendations.

    Main Results:

    Related Experiment Videos

    • Maximum urethral closure pressures in female dogs ranged from 13.0 to 46.0 mm Hg (mean 23.9 ± 11.8 mm Hg).
    • Younger female dogs (<2 years) had significantly lower maximum urethral pressures than older females (P < 0.025).
    • Maximum urethral closure pressures in male dogs ranged from 25.0 to 36.0 mm Hg (mean 28.3 ± 4.0 mm Hg).

    Conclusions:

    • This study provides normative urethral pressure profile data for healthy dogs.
    • Age influences urethral closure pressure in female dogs, highlighting the need for age-specific reference ranges.
    • Canine urethral pressure profilometry can be a valuable diagnostic tool in veterinary urology.
