Perineal Urethrostomy
Urinary obstruction in male cats can be life-threatening. Perineal urethrostomy opens the urethra to prevent life-threatening obstructions to your pet.

Urinary Obstruction in Male Cats
Mucus, crystals, small stones, and inflammation that have formed in the urinary tract block urine outflow from the bladder. The cause of the formation of obstructing material is not known but viral infections, diet, stress, and water intake may play a role.
Clinical Signs of Urinary Obstruction
- Straining to Urinate
- Frequent Urination
- Urinating Outside the Litter Box
- Blood in the Urine
- Vocalization & Restlessness
- Painful Urination
- Hiding
- Loss of Appetite
- Weakness & Lethargy
- Abdominal Distention
- Reluctance to Move
Diagnosis & Immediate Care
Inability to express the bladder or pass a urinary catheter support lower urinary obstruction and patients with urinary obstruction will need immediate relief and drainage of their bladder. Abdominal imaging (radiographs +/- ultrasound) may help determine if urinary stones are present or if bladder rupture has occurred. Bloodwork is required to look for abnormalities requiring correction with IV fluid therapy and to evaluate the overall health of each patient.
Perineal Urethrostomy
In cats with recurrent lower urinary obstructions, surgical intervention helps mitigate the life threatening occurrence that accompanies the obstructions.
Perineal urethrostomy (PU) creates a new wider opening for urine to pass.
The surgery does not prevent bladder inflammation or stone formation from reoccurring, but it does minimize the risk of re-obstruction.
Complications
& Risks
- Bleeding
- Straining to Urinate
- Urine Leakage Into Surrounding Tissues
- Urethral Stricture (Closing) of the Opening
- Recurrent Lower Urinary Tract Inflammation and/or Infection
After Surgery
During this time pets should be kept indoors, separated from other pets, and not be allowed to jump up on/off furniture or run up and down stairs. Your pet should be confined to a small area with access to food and water.
