This list of dog diseases is a selection of diseases and other conditions found in the dog. Some of these diseases are unique to dogs or closely related species, while others are found in other animals, including humans. Not all of the articles listed here contain information specific to dogs.
Urinary casts are microscopic cylindrical structures produced by the kidney and present in the urine in certain disease states. They form in the distal convoluted tubule and collecting ducts of nephrons, then dislodge and pass into the urine, where they can be detected by microscopy.
Hematuria can be classified according to visibility, anatomical origin, and timing of blood during urination. [1] [6]In terms of visibility, hematuria can be visible to the naked eye (termed "gross hematuria") and may appear red or brown (sometimes referred to as tea-colored), or it can be microscopic (i.e. not visible but detected with a microscope or laboratory test).
Microscopic hematuria is sometimes observed in healthy people after exercise [98] or as a consequence of contamination of the sample with menstrual blood. [97] Pathologic causes of hematuria are diverse and include trauma to the urinary tract, kidney stones , urinary tract infections , drug toxicity , genitourinary cancers, and a variety of ...
Most patients have been reported to have gross or microscopic hematuria. [8] Significantly increased serum lactate dehydrogenase levels and proteinuria may also be observed. [7] Renal angiography is still the gold standard, but CT renal angiography, CT angiography, and DMSA radioisotope scan can also be used to establish the diagnosis. [4]
Blood tests (to monitor levels of platelets, red blood cells, and white blood cells), stool tests (especially to check for microscopic or macroscopic levels of fresh or old blood), urinalysis (to help monitor kidney function, like blood urea nitrogen, or BUN, levels, pH, and for blood in the urine- hematuria) [3]
Capillaria plica (dog bladder worm) is a parasitic nematode which is most often found in the urinary bladder, and occasionally in the kidneys, of dogs and foxes. [1] It has also been found in the domestic cat, and various wild mammals.
