Knowledge of urolith composition is important because contemporary methods of detection, treatment and prevention of the underlying causes of urolithiasis largely depend on knowledge of urolith composition.
Definitively diagnosing canine hyperadrenocorticism (Cushing's disease) can be exceptionally difficult because nonadrenal illness can affect the test results. However, I think that the urine cortisol:creatinine ratio (UC:Cr) serves an invaluable role in ruling out canine Cushing's disease since a dog with a normal UC:Cr almost assuredly does not have Cushing's disease.
Feline urinary problems can frustrate both owners and veterinarians. To help us discern whether the problem is medical or behavioral or due to litter box issues, we have the owners complete this form. Inappropriate housesoiling is often due to a combination of these issues, and this form helps us narrow in on the cause and correct it. --Maureen Owen, LVT Fishers, Ind.
Interpretation of color is subjective, and therefore varies from person
to person. The most reliable results are obtained when a standardized method
is consistently used. Urine color should be evaluated by placing a standardized
volume of urine in a standardized clear plastic or glass container and viewing
the sample against a white background with the aid of a good light source.
