Urolithiasis in rabbits and guinea pigs-pathophysiology and diagnosis

Urolithiasis is a common condition in both rabbits and guinea pigs. Their particular type of calcium metabolism and other predisposing factors can lead to the formation of predominantly calcium carbonate stones in the urinary tract of these animals. Clinical signs and urinalysis can lead to a tentative diagnosis of urolithiasis. Radiographic imaging and ultrasonography are used to confirm the diagnosis. Additional blood testing can be helpful in estimating each animal's prognosis.
