Ureter Stones in Cats
Ureterolithiasis in Cats
Ureterolithiasis is a condition which involves formation of stones that may lodge into the ureter, causing its blockage. A muscular tube which connects the kidney to the bladder, the ureter also carries urine from kidneys to the bladder. Typically, ureter stones originate in the kidneys and later pass down into the ureter.
Depending on the size and shape of the stone, the stone may pass down to the bladder without any resistance or it may partially or completely obstruct the ureter, resulting in the dilatation of the upper portion of the ureter and subsequent kidney damage.
There are a number of different types of stones found in animals and type of stone may vary in according to breeds, age, and sex of the cat.
Symptoms and Types
Some cats with ureterolithiasis display no symptoms, especially during the initial stages. Otherwise, be attentive to the following symptoms:
The underlying cause may vary depending on the type of the stone. Typical causes include:
Your veterinarian will conduct a complete medical history and perform a physical examination on your cat. He or she will then use routine laboratory tests including complete blood count, biochemistry profile, electrolyte panel, and urinalysis to assess the condition of your cat and severity of the disease. These tests also help in evaluating your pet for any other concurrent disease or condition.
Abdominal X-rays are extremely useful in visualizing the stones and their size; it will also confirm if the kidney has become enlarged as a result of the stones. Similarly, X-rays will depict if the ureter is intact or ruptured. In some cases, a special dye is injected intravenously and X-rays are taken afterward. This helps better visualize the stones by providing contrast. Ultrasound scans is another method for detecting ureter stones and kidney size.
