The International Veterinary Renal Pathology Service (IVRPS) is a collaborative effort between the Ohio State University and Texas A&M University.

Our mission is to improve health care for individual patients with kidney disease and generate new knowledge about renal diseases in animals by expertly performing thorough pathologic evaluations of kidney specimens obtained from dogs and cats, as well as other animals.  

IVRPS goals

The work performed by the IVRPS is centered around the following operational goals:

  • To perform histologic, ultrastructural and immunohistologic examinations of kidneys that will assist veterinarians, especially nephrologists and specialists in academic and private practices, with the evaluation of their patients with kidney disease.
  • To effectively communicate pathologic findings and their implications, in a timely manner, with each patient's attending clincian(s).
  • To collect detailed clincial information about the features, course, response to treatment, and outcome of pathologically well-defined kidney diseases in animals and integrte the information with the pathologic findings. 
  • To generate and maintain a database containing the clinical and pathologic information collected about pathologically well-defined kidney diseases in animals. To use the resources of the IVRPS, including the database and technology for gathering and managing the data, to facilitate retrospective and prospective investigations that will advance understanding of the causes, treatment and prevention of renal diseases in dogs, cats and other animals.
