Xanthine Urinary Tract Stones in Cats



Voiding urohydropulsion is effective for removing the smaller xanthine uroliths that will easily pass through the urethra, but surgery is still the best way to remove larger uroliths from the lower urinary tract. Perineal urethrostomy surgery may minimize recurrent urethral obstruction in male cats, but this condition is known for recurring in many cats that have been affected.


Urine pH may be increased to prevent xanthine uroliths, and a low-purine diet may be fed along with plenty of water to increase urine output. Depending on your cat's overall health and the severity of this condition, your veterinarian may also recommend a diet that is designed for cats suffering renal failure. The goal is to reduce the amount of ingested purine, along with reducing the formation of acid urine, in addition to increasing the amount of urine that is voided from the bladder so that the passages remain clear of stone forming chemicals.


Living and Management


Your veterinarian will schedule monthly follow-up appointments for your cat in order to conduct urinalysis, contrast X-rays, or ultrasonography exams. Your cat's treatment may be adjusted to how well its health is progressing since the initial treatment. Xanthine uroliths often recur in cats.
