How long does it take a kidney stone to form?

You can have kidney stones for years without knowing they’re there. As long as these stones stay in place within your kidney, you won’t feel anything. Pain from a kidney stone typically starts when it moves out of your kidney. Sometimes, a stone can form more quickly — within a few months.

Talk with your healthcare provider about your risk factors. They might do a 24-hour urine test to check how quickly you develop stones.
