What is Prescrotal Urethrostomy?

A prescrotal urethrostomy is a surgical procedure that involves creating a permanent opening for the urethra through the prescrotal region of a male canine. Let’s delve into the details:

Indications:

• • A prescrotal urethrostomy is indicated when the urethral opening is persistently obstructed or is too narrow.
  • It is most commonly performed on male cats suffering from feline urologic syndrome, a condition that makes them prone to protein plugs, bladder “sand,” or bladder stones that enter the urethra and obstruct urine flow.
  • In dogs, this procedure is indicated when bladder stones have traveled to the urethra and caused partial or complete obstruction.
  • Breeds commonly affected include Dalmatians and Lhasa Apsos.
  • Urethrostomy may also be necessary in cases of severe penile trauma or scarring/stricture that prevents normal urine passage.

Procedure:

• • The surgery is performed under general anesthesia (although it can be done under sedation and local anesthesia in unstable patients).
  • The prescrotal region is the area just caudal to the os penis (the bone within the penis).
  • An artificial permanent hole is created in the urethra, allowing urine to bypass any obstructions.
  • In intact male dogs, prescrotal urethrostomy requires simultaneous castration if not already done.

Postoperative Care:

• • Patients must be kept calm and inactive during recovery.
  • Bleeding from the surgical site may occur for up to 10 days postoperatively.
  • Cats should have constant access to a litter box with dust/clay-free litter.
  • Dogs may feel an increased urgency to urinate and should be walked more often.
  • An Elizabethan collar is necessary until suture removal.

Risks and Complications:

• • As with any surgery, there are risks, including infection, bleeding, and anesthesia-related complications.

 

Remember that individual cases may vary, and consulting a veterinarian is essential for proper diagnosis and treatment.
