Conditions We Treat: Kidney Stones

Kidney stones are hard objects in the urinary tract made up of millions of tiny crystals.

Kidney stones are formed when the body’s system for filtering urine becomes too concentrated. Rather than being filtered out through the urine, substances like calcium, oxalate and phosphate separate as crystals and attach to one another, accumulating into a small mass, or stone.

Kidney Stones: What You Need to Know

  • Kidney stones often produce intense pain that starts in the lower back and may move to the side or groin. 
  • Those who have had a kidney stone before are at greater risk of developing another.  
  • To prevent kidney stones, drink plenty of water every day. 
  • Once a stone has passed, it can be evaluated to determine the cause. Knowing why your stone formed is the best way to reduce your risk of future stones.
