Traumatic urethral injuries in male dogs and cats heal well with intact mucosa. Management involves assessment, urinary diversion, and surgical repair or bypass, prioritizing function and avoiding strictures.

Area of Science:

  • Veterinary Surgery
  • Urology
  • Small Animal Medicine

Background:

  • Urethral injuries are common in male dogs and cats.
  • The urethral epithelium exhibits significant regenerative capacity.
  • Effective healing by second intention requires mucosal continuity.

Purpose of the Study:

  • To outline principles for managing traumatic urethral injuries in male dogs and cats.
  • To discuss various treatment options for urethral defects.
  • To emphasize the importance of preserving urethral function and avoiding strictures.

Main Methods:

  • Accurate patient assessment, including injury extent.
  • Correction of electrolyte and acid-base disturbances.
  • Urinary diversion (cystostomy or catheterization) and urine extravasation drainage.

  • Surgical repair or bypass (urethrostomy) of injured urethra.
  • Scrotal urethrostomy is preferred in male dogs for penile urethral injuries.

    • Main Results:

    • Healing by second intention is effective if mucosal continuity is maintained.
    • Urinary diversion is crucial for pelvic or perineal urethral defects.
    • Primary repair is an option for transection injuries.
    • Urethrostomy bypasses injured segments, with scrotal site being common.

    Conclusions:

    • Successful management hinges on accurate assessment and appropriate surgical intervention.
    • Meticulous surgical technique is vital to minimize fibrosis and maintain luminal diameter.
    • Goals include avoiding urethral stricture and preserving urinary function.
