Surgery poses the risk of infection and of causing kidney damage, so it is only used when other treatment options aren't working.
What is the procedure to remove kidney stones in cats?
In order to correctly identify the stones, a procedure called extracorporeal shock wave lithotripsy (ESWL) may be performed. During this noninvasive procedure, shock waves will be used to break up the stones, allowing pieces to be removed from the urinary tract and identified. Identifying the minerals in the stones can help determine the best treatment for the cat.

What is the function of the kidneys?
The kidneys are responsible for filtering the blood, removing wastes such as mineral salts, urea, and toxins, and excreting these filtered wastes with water in the form of urine. Some of these wastes that are normally excreted by the kidneys aren't completely soluble and remain in the kidneys, forming crystals or renal calculi. Over time, these crystals can form stones, known as nephroliths, and cause a condition known as nephrolithiasis.

He or she will then perform a complete physical examination, ultrasound imaging, and urinalysis. However, in order to confirm the diagnosis, identify the mineral content of the stones, and develop a proper course of treatment, pieces of nephroliths must be retrieved for analysis. This is usually achieved by performing a procedure known as extracorporeal shock wave lithotripsy (ESWL), in which stones are broken up within the urinary tract using sound waves.
What does it mean when a kidney stone is inactive?

The kidneys are a complex and delicate organ in your cat’s body that have the job of removing waste substances and toxins from the bloodstream and turning them into urine. This is then removed from the body when your kitty has a pee. Inside the kidney there are thousands of little filtration units called nephrons. Within each nephron, there are loops of blood capillaries and a set of tubes. Waste products pass out of the blood capillaries and into the tubes where urine is produced. A series of ducts drain the urine from the nephrons into a larger tube called the renal pelvis. This leads into the ureter and exits the body.

What are kidney stones made of?
Bladder stones, says Richard Goldstein, DVM, associate professor of small animal medicine at Cornell University’s College of Veterinary Medicine, are composed of minerals—either struvite or calcium oxalate—while kidney stones are always made of calcium oxalate. “These minerals are present naturally in a cat’s body,” he says, “and the stones form when the minerals exceed a certain threshold of concentration in the urinary system. When the concentration goes over that threshold, they start to form crystals, and the crystals accumulate and may grow into stones. We don’t know why this process takes place, but we’ve observed that it tends to occur frequently in domesticated cats, especially in those that are not very active, don’t take in enough fluids, and don’t urinate enough.”
What are the functions of a cat's kidneys?
Among them are: to filter metabolic waste such as urea, mineral salts, and various toxins from circulating blood; to help regulate the volume of body fluids and the blood levels of important chemicals and hormones; to initiate the recirculation of purified blood throughout an animal’s system; and to facilitate the excretion of the filtered-out waste products (mixed with water to form urine) before they reach toxic concentrations in the body. Most cats will go through life without experiencing a serious disruption in these vital processes. Some others, however, will experience urolithiasis—a potentially lethal condition marked by the formation of small stones (uroliths) somewhere within this elaborate system.
Can a cat's urine be blocked?
In the worst case, they can slip into a cat’s urethra and interfere with the passage of urine.
