Many veterinarians and technicians do not routinely evaluate blood films microscopically, largely because they lack confidence in either preparing a well-made blood film or in being able to accurately identify important abnormalities.
In this article, I describe the most common clinical signs and physical examination findings in hyperthyroid cats. I also review the available diagnostic methods, including their advantages and disadvantages.
Reference ranges are established by testing a group of apparently healthy normal animals. But even if a value falls within the reference range, it may not be normal for that animal if the animal is ill.
Calcium oxalate (CaOx) was the most common (47 percent) mineral in feline uroliths submitted to the Minnesota Urolith Center during 2003 (Table 1). More than two-thirds of feline nephroliths were composed of CaOx.
As discussed in last month's Diagnote, the underlying causes of different types of uroliths vary. It follows that medical and/or surgical procedures designed to safely and effectively treat different types of uroliths also vary. The objective of the second part of this series is to provide an overview of risks and benefits associated with surgical and medical therapy of urolithiasis. Therapeutic caveats associated with treatment of specific types of uroliths will be the subject of next month's Diagnote.
