Kidney stones are result of concentration of substances like calcium in blood. These might be associated with other conditions such as bowel disease and urine infection. It is also appear due to accumulation of uric acid in blood. Uric acid stones make up about 8% of all stones. It is more common in men because they’re most often associated with gout or chemotherapy. Stones found in women are usually the result of urinary tract infection. Some other types of stones are however hereditary, and tend to run in families and they don’t follow any pattern for their cause.

Answer:
In addition to the other answers, stones can also be caused by excess uric acid. Uric acid crystals are what cause gout. Bacteria, such as the Proteus species, are involved in the formation of certain kidney stones as well (phosphate stones, I believe). The acidity of the urine also plays a factor, as does what kinds of food you eat. Actually, there are a lot of factors that go into the conditions required to create kidney stones.

Answer:
There are different types of kidney stones (meaning the stones are made up of different substances). The kidney acts as a sieve for the blood, and when too much of a certain substance is in the blook (like calcium or uric acid for example), the substance precipitates in the kidney forming a stone.

What are kidney stones?

Kidney stones are made of salts and minerals in the urine that stick together to form small "pebbles." They can be as small as grains of sand or as large as golf balls. They may stay in your kidneys or travel out of your body through the urinary tract. The urinary tract is the system that makes urine and carries it out of your body. It is made up of the kidneys, the tubes that connect the kidneys to the bladder (the ureters), the bladder, and the tube that leads from the bladder out of the body (the urethra).

When a stone travels through a ureter, it may cause no pain. Or it may cause great pain and other symptoms.

What causes kidney stones?

Kidney stones form when a change occurs in the normal balance of water, salts, minerals, and other things found in urine. The most common cause of kidney stones is not drinking enough water. Try to drink enough water to keep your urine clear (about 8 to 10 glasses of water a day). Some people are more likely to get kidney stones because of a medical condition or family history.

Kidney stones may also be an inherited disease. If other people in your family have had them, you may have them too.

What are the symptoms?

Kidney stones often cause no pain while they are in the kidneys, but they can cause sudden, severe pain as they travel from the kidneys to the bladder.

Call a doctor right away if you think you have kidney stones. Watch for severe pain in your side, belly, or groin or for urine that looks pink or red. You may also feel sick to your stomach (nausea) and may vomit.
