Most kidney stones will be small enough (no more than 4mm or 0.2in in diameter) to be passed out in your urine. It may be possible to treat these at home.
However, small kidney stones may still cause pain. The pain from smaller kidney stones usually lasts a couple of days and disappears when the stone has been passed.
If a kidney stone is too big to be passed naturally (6-7mm in diameter or larger), you may need to have treatment to remove it another way.
This could include:
- extracorporeal shock wave lithotripsy (ESWL)
- ureteroscopy
- percutaneous nephrolithotomy (PCNL)
- open surgery
These procedures are explained in more detail below. The type of treatment you have will depend on the size and location of your stones.
