    This study explored urethral hyperthermia in dogs after cystoprostatectomy and ileal loop diversion. Complete urethral destruction was achieved in some dogs, suggesting potential for this surgical approach.

    Area of Science:

    • Veterinary Surgery
    • Urology
    • Oncology

    Background:

    • Cystoprostatectomy and ileal loop diversion are complex procedures.
    • Urethral preservation or destruction is a critical consideration in these surgeries.
    • Hyperthermia is being investigated as a therapeutic modality.

    Purpose of the Study:

    • To evaluate the efficacy of urethral hyperthermia in achieving urethral destruction post-cystoprostatectomy and ileal loop diversion in male dogs.
    • To assess the feasibility and complications associated with the surgical technique.

    Main Methods:

    • Nine male dogs underwent cystoprostatectomy, ileal loop diversion, and urethral hyperthermia.
    • Survival was monitored for six weeks.
    • The degree of urethral epithelial destruction was histologically assessed.

    Main Results:

    • Five out of nine dogs survived the six-week period.
    • Of the survivors, three dogs exhibited complete urethral destruction.
    • Two dogs showed partial destruction (95% and 50%), with incomplete destruction at the proximal end.

    Conclusions:

    • Urethral hyperthermia, combined with cystoprostatectomy and ileal loop diversion, can lead to significant urethral destruction in dogs.
    • Complete urethral destruction may be enhanced by resecting the proximal urethra post-irrigation.
    • The procedure had few complications, and further modifications like dorsal slit and meatotomy might avert potential complications.
