Kidney Stones

Kidney stones form in the kidney and cause pain when they move from the kidney to the bladder. The most common form of kidney stone contains calcium, but other forms include uric acid and cystine. Stone analysis along with medical evaluation provides an understanding of why they form.

Prevalence and Risks

The prevalence of kidney stones has been steadily increasing in the United States for the last 30 years. The incidence in the United States is about 5% of the population, which means about 1 in 20 people will develop a kidney stone in their lifetime. White men are more at risk than anyone, but men and women of all ages and ethnicities are at risk. Once you have had a kidney stone, you are at an increased risk for another stone.

Often kidney stones produce pain, but can also cause other complications such as infection and bleeding.

Of course, when a stone is passed or removed, it is easy to forget about the problem, but you are likely to develop another stone. Treatment in our clinic is aimed at preventing recurrence of kidney stone.

There are many risk factors contributing to stone formation including family history, diet, and metabolic abnormalities.

Who is at risk for kidney stones?

Everyone is at risk. However, there are certain risk factors that may increase your chances of forming a kidney stone. These factors include family history, diet, and metabolic abnormalities.

If I had one kidney stone, how likely am I to get another kidney stone?

Once you have had a kidney stone, you are at increased risk for forming another stone. Recurrence in men is 70% to 80% and in women, 40% to 50%.

What do I need to bring to my first appointment?
