My 3-year British Shorthair had urethral stricture after surgery and keeps closing up what can help?

Post-urethrostomy urethral adhesion means the inner walls stick together, commonly from poor mucosa-skin alignment, local tension, subcutaneous urine leak, or the cat licking the wound, causing difficult or no urination. It may be a surgical complication or from poor technique or aftercare.

For severe adhesion, a second surgery may be needed to separate the walls and dilate the urethra with a dilator or two-lumen catheter, extending dilation by healing progress. Use topical and oral antibiotics to prevent infection, and stop the cat from licking the opening while keeping it clean.
