Calcium oxalate urolithiasis is the most common urinary stone type in cats, causing significant pain and requiring lifelong management to prevent recurrence.
Calcium oxalate urolithiasis causes significant suffering through mechanical trauma as rough stones abrade the urothelium, dysuria during urination, and complete obstruction if stones lodge in the urethra. Cats with urinary obstruction develop life-threatening uremia within 24-48 hours and experience extreme pain and distress. Surgical removal, while effective, involves anesthesia and postoperative recovery with incisional discomfort. The high recurrence rate means many cats undergo multiple surgical procedures over their lifetimes. Preventive management through dietary modification and enhanced water intake is crucial to avoiding repeated episodes and the chronic pain associated with this condition.
