How do you identify calcium oxalate crystals?
Calcium oxalate crystals are found primarily in acidic urine but also are seen in neutral and even alkaline urine. When seen in urine with an alka- line pH, the dihydrate form of calcium oxalate tends to maintain its classic, easily identifiable shape.
How do you test for calcium oxalate?
How are they diagnosed?
- Urine test. Your doctor may request a 24-hour urine sample to check levels of oxalate in your urine.
- Blood test. Your doctor can test your blood for the gene mutation that causes Dent disease.
- Imaging tests. An X-ray or CT scan can show stones in your kidney.
How do you treat calcium oxalate crystals in cats?
“Treatment of oxalate stones usually requires surgical removal, known as a cystotomy.” Less commonly, bladder stones may be removed via a process known as cystoscopy. This involves inserting a small camera into the bladder, with a basket or retrieval device that can be used to remove the stones.
When do calcium oxalate stones develop in cats?
Most calcium oxalate stones develop in cats between ages 5 and 14 years. 35% of cats with calcium oxalate bladder stones have elevated blood calcium ( hypercalcemia ). Cats with calcium oxalate bladder stones tend not to have crystals in their urine (while those with struvite stones do tend to have struvite crystals in their urine).
Can a cat get struvite or calcium oxalate bladder stones?
Now, a cat is just about equally likely to develop struvite or calcium oxalate bladder stones. Unfortunately, this change isn’t simply due to a decrease in the number of struvite stones.
What can you feed a cat with calcium oxalate in it?
Feed canned cat food only. The high water content of canned foods promotes the formation of dilute urine. Calcium oxalate crystals are less likely to come out of solution and form stones in dilute urine. If necessary, you can even add a little extra water to canned food.
What kind of stones are in a cat’s urine?
Oxalate bladder stones are composed of a mineral called calcium oxalate. While a small amount of calcium oxalate crystals in the urine can be a normal finding, some cats have very high numbers of these crystals. Under certain conditions, these crystals can combine into stones within the bladder or other areas of the urinary tract.
What are symptoms of bladder stones in cats?
The most common symptoms of bladder stones in the cat are hematuria (blood in the urine) and dysuria (straining to urinate). Hematuria occurs because the stones rub against the bladder wall, irritating and damaging the tissues and causing bleeding.
How do you treat bladder stones in cats?
The most common treatment for bladder stones is a cystotomy, in which the bladder is surgically opened and the stones are removed. Cats usually recover quickly from this common surgery. Bladder stones can also be treated with laser or shockwave lithotripsy.
How do you dissolve calcium oxalate?
One method for dissolving calcium oxalate in the lab is the application of a compound called ethylenediaminetetraacetic acid or EDTA. EDTA is highly effective at binding the calcium ions and thereby decreasing the concentration of calcium in solution, shifting the reaction equilibrium so that more calcium oxalate will dissolve.
What causes calcium oxalate?
Calcium oxalate stones are generally caused by excess consumption of food stuff that contain high amounts of calcium. In addition, excessive intake of Vitamin C that is metabolized to oxalate may lead to hyperoxaluria and an increase in stone formation.
