CANINE COMPOUND UROLITHS 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.
PREVENTION DIAGNOSTIC CONSIDERATIONS
Identify causes for the material at the center of urolith(s). Culture the urine
MEDICAL CONSIDERATIONS
Follow prevention strategies to minimize the material at the center of urolith(s). Culture and susceptibility testing provides the most accurate method for selecting effective antimicrobials. Avoid suture entering the lumen of the urinary bladder
NUTRITIONAL CONSIDERATIONS
Follow nutritional recommendations for preventing the mineral at the center of urolith(s).
MONITORING CONSIDERATIONS
Follow monitoring strategies to minimize the material at the center of urolith(s). Medical imaging every 6 to 12 months to detect recurrent stones when small to permit their easy removal without surgery.
** 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. In depth recommendations and references are available on our website: urolithcenter.org under the resources tab.
