Most kidney stones are about the size of a grape seed. Stones of this size are small enough to pass through your urine. Once it is passed, a stone can be analyzed. This wait-and-see approach is called expectant therapy. If pain is a problem, ask your doctor about pain medicines. Then follow their directions for how much water to drink. Drinking more water creates more urine to flush out your stone. Also be sure to strain your urine. Take any stones you pass to your doctor for analysis.

Drinking lots of water may help your stone pass. Water also dilutes the chemicals in your urine. This reduces your risk of forming new stones. You may be told to drink 8, 12-ounce glasses of water a day. Don't drink liquids that dehydrate you. This includes drinks that have caffeine or alcohol.

Straining your urine lets you collect your stone for analysis. Use the strainer each time you urinate. Strain your urine for as long as your doctor suggests. Watch for brown, tan, gold, or black specks or tiny pebbles. These may be kidney stones.

Your doctor may give you medicine that makes it more likely for you to pass the kidney stone.

Follow up by taking any stones you find to your doctor for analysis. The type of stone you have will determine your diet, any medicines, and prevention program. You may need more tests in the future. These tests will help ensure that new stones are not forming. Contact your doctor if you have new symptoms or questions. Keep your follow-up appointments.
