Male cats have a long, narrow urethra that can become blocked by crystals, stones or mucus plugs. A urinary blockage is a life-threatening emergency, and some cats become blocked again and again despite treatment and diet changes.
A perineal urethrostomy, often called a PU, is a surgery that creates a wider opening for urine to pass. It's usually recommended for cats who have had repeated blockages or whose urethra has been damaged, to help prevent future emergencies.
Signs of a Urinary Blockage in Cats
A blocked cat can become seriously ill within hours. If your cat shows any of these signs, come in right away or contact the nearest emergency hospital:
- Straining in the litter box with little or no urine
- Going in and out of the litter box often
- Crying out while trying to urinate
- Licking the genital area
- Vomiting, hiding or not eating
- Weakness or lethargy
What to Expect With PU Surgery
Before surgery, your cat's blockage is relieved and they're stabilized, and your vet may recommend bloodwork and urine tests. During surgery, your cat is under general anesthesia and closely monitored, with pain medication to keep them comfortable.
After surgery, your cat will wear a cone and may need shredded paper or a special litter while the area heals. Medications, rechecks and a urinary diet may be recommended. Most cats recover well and go on to live comfortable lives.
