Radiograph

General Information

Osseous transformation of the lining of the urinary tract is uncommon. There is little know as to why this occurs and if recurrence is likely.

Diagnostic

• Biopsy urothelium to identify cause for urothelial transformation into pathological calcification (e.g. neoplasia, trauma, ischemia) or ectopic ossification (e.g. trauma, bleeding, inflammation, genetic variants).

Medical

• Most cases are idiopathic and treatment is unknown. • Reduction in urine specific gravity and changes in urine pH may reduce nucleation of minerals over osseous surfaces. See specific urolith recommendations (e.g. CaOx) for preventing mineral types that formed over osseous portion at z.umn.edu/mnurolithRX. • PUBLICATON: Ectopic Bone as a Nidus for Calcium Oxalate Urocystolithiasis in a Cat, Lulich, J.P., Prasad, H.S., Manno, M. and Bagley, B. (2017), J Vet Intern Med. doi:10.1111/jvim.14859

Nutritional

• Canned foods or adding water to food may lower specific gravity and minimize nucleation or minerals that form over osseous portion.

Monitoring

Medical imaging every 12 months to detect recurrence. Recurrence is an indication for further evaluation and alternative treatment strategies.

Disclaimer

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.
