Perineal / Scrotal - Urethrostomy

Surgical Procedure

A perineal urethrostomy is a surgical procedure used to treat urethral blockage in male dogs or cats caused by either stones (crystals) or a tightening of the urethra walls (i.e. narrowing of the opening from stricture or growth) due to injury or congenital defect. The procedure involves bypassing the penile urethra and redirecting it through an opening in the perineum to outside the body where urine can flow. The bladder still controls the flow of urine and the upper area of the urethra is wider than the lower penile area of the urethra so there is less chance of a stone blockage.

The procedure can, however, increase urinary tract infections, and a prescription diet is still needed to reduce the chance of crystal and stone formations.

Process overview

Pre-Surgery Preparations

All procedures require pre-operational bloodwork. Food and water is restricted 8 to 12 hours prior to surgery to prevent possible aspiration due to vomiting. Depending on the case and procedure, additional diagnostic tests may be required for example EKG, Xray, or ultrasound. We may also recommend an anesthesia specialist if necessary to oversee the anesthesia and health monitoring of your pet.

During Surgery

Your pet will given a sedative to facilitiate preparation of the surgical site and placement of IV cather. The next step is to provide oxygen, fluids, and thermal support. All medical equipment or apparatus will then be connected so as to monitor your pet's vital signs. Your pet is then anesthetized (induced) and appropriate pain management (epidural, local anesthetic, constant rate infusion/CRI) is administered as needed. We will continue to regulate and monitor your pet throughout the procedure.

Immediately following the procedure, we continue to administer fluids and observe your pet for a few hours until your pet is fully awake. Discharge instructions will be provided during which all your post-op questions will be answered by the doctor and your pet is able to go home to start his/her recovery process. Follow-up post-operative exams and post-operation pain medication is provided.
