Cats with Kidney Stones

Cats with Kidney Stones

Help us solve this common, costly and devastating problem.  We need whole, formalin-fixed kidneys of cats with nephroliths. If cats have a kidney removed during therapy, succumb to their illness, or are humanely euthanized; place whole, intact kidneys (after carefully removing the outer capsule) in formalin.  We’ll cover the cost of shipping; please email Dr. Jody Lulich at [email protected].

One of the most compassionate acts we can perform as veterinarians and cat owners is to contribute to the efforts of scientists working to cure diseases.

Genetic Risk Factors for Dogs with Urinary Stones

Genetic Risk Factors for Dogs with Urinary Stones

Calcium Oxalate Uroliths

canine calcium oxalate urolithDr. Eva Furrow in the canine genetics laboratory is investigating genetic risk factors for urinary stones. She is currently seeking DNA samples (cheek swabs or blood) from dogs with CaOx stones. While the Border Collie, Dachshund, Miniature Schnauzer, Bichon Frise, and Shih Tzu breeds are her main focus, DNA from any affected breed can be helpful. Please see the following website for more information: 

Hereditary Xanthine Uroliths

Dr. Furrow also recently discovered genetic mutations for xanthinuria (the cause of hereditary xanthine stones) in Cavalier King Charles Spaniels, Toy Manchester Terriers, and a mixed breed dog. Tests for these mutations are available:
Dachshund and Chihuahua dogs with a history of xanthine stones may be eligible for free testing.   

Contact Dr. Furrow at [email protected] for more information about either study or other genetic stone types.
