I have kidney stone which is 4mm so i do for this?

Kidney stone: The first thing to do is increase your fluid intake. You should drink 2 liters of fluid daily. This will help you pass the stone. You may require a medication such as Flomax (tamsulosin) to help the stone pass easier. If the stone gets stuck, you may need the help of a urologist.

Drink: If the stone is in the kidney you may have to do nothing. If you have pain the stone has moved and lodged in the drainage system. If this occurs drink lots of fluid. The extra urine output should distend the drainage system making it easier for the stone to pass and less likely for it to cause obstruction. Severe pain, nausea or vomiting go to er. It should be small enough to pass on its own.
