Uroliths with a center composed of a different material than the outer layer(s) are called compound. Compound uroliths commonly occur when metabolic uroliths (e.g. calcium oxalate, urate) contribute to urinary tract infections with bacteria that promote struvite formation, or when suture material or other intraurocystic foreign material promotes mineralization over its surface, or when treatment/diet administered prior to urolith removal alter urine pH or crystal solubility.

• Identify causes for the most abundant mineral near the center (see recommendations for specific mineral types at z.umn.edu/mnurolithRX)

• If present, prevent infection-induced struvite and calcium phosphate carbonate by repeating urine cultures and administering antibiotics when needed.. • Next, select therapy to prevent the most abundant mineral near the center (see recommendations for specific mineral types at z.umn.edu/mnurolithRX). • Then, make adjustments in therapy to prevent the other minerals without opposing therapy to prevent the most abundant mineral near the center (e.g. feed therapeutic canned foods or add water to achieve a specific gravity less than 1.030 for cats, adjust urine pH, and consider medications that reduce minerals).

• Foods designed to minimize the abundant mineral at the center of the urolith can be found at z.umn.edu/mnurolithRX. • Prevent infection-induced minerals by controlling infection; not with food.

• Select foods designed to minimize minerals at, or near the center of the urolith that are not infection-induced. z.umn.edu/mnurolithRX • Prevent infection-induced minerals by controlling infection; not with food.

We advise reviewing manufacturer's literature regarding selected therapeutic foods to determine indications and contraindications. For pets with multiple health concerns,we suggest that the selection of diet should take into consideration all health needs of the pet.
