Introduction
If you've ever passed a kidney stone, you're not likely to forget the experience — it can be excruciatingly painful. Kidney stones (renal lithiasis) are an ancient affliction dating back to the age of the Egyptian pyramids, yet they are still a common disorder today. The incidence of kidney stones has been increasing in recent decades. Although the reasons for this are still unclear, many experts believe that diet choices and lack of fluids are important factors that have contributed to this increase.

Not all kidney stones cause symptoms. They're often discovered when you have X-rays for an unrelated condition or when you seek medical care for other problems, such as blood in your urine or recurring urinary tract infections. The pain becomes agonizing only when a kidney stone breaks loose and begins to work its way down from your kidneys to your bladder through the connecting tube (ureter).

Kidney stones usually form when your urine becomes too concentrated. This causes minerals and other substances in urine to form crystals on the inner surfaces of your kidneys. Over time, these crystals may combine to form a small, hard mass, or stone.

Most small kidney stones pass into your bladder without causing any permanent damage. Still, it's important to determine the underlying cause so that you don't form more stones in the future. In many cases, you can prevent kidney stones simply by drinking more water and making a few dietary changes
Treatment for kidney stones varies, depending on the type of stone and the cause. You may be able to move a stone through your urinary tract simply by drinking plenty of water — as much as 2 to 3 quarts a day — and by staying physically active.

Stones that can't be treated with more-conservative measures — either because they're too large to pass on their own or because they cause bleeding, kidney damage or ongoing urinary tract infection — may need professional treatment. Procedures include:
