Kidney stones

Skip Navigation

Kidney stones are small stones made of minerals in the urine that stick together. They can cause severe pain as they travel through the ureters (tubes that connect the kidneys and the bladder) to exit the body when you urinate.

Your doctor may give you medicine to ease the pain until you pass the stone. If the stone is too large or gets stuck, other treatment is needed.
