To pass a kidney stone at home, drink 2 to 3 quarts of water per day to flush out the urinary tract, advises Mayo Clinic. Take over-the-counter pain relievers, such as acetaminophen ibuprofen or naproxen sodium, to alleviate mild discomfort. A doctor may prescribe an alpha blocker, a medication that helps relax the ureter muscles, so that you can pass the stone with as little pain as possible.
Most kidney stones pass within 48 hours with adequate fluid intake, according to MedicineNet. If the pain is severe, a doctor may provide an injectable anti-inflammatory drug or oral narcotics.
The size of the stone, your size and age, and the presence of pregnancy or prostate enlargement are factors that affect your ability to pass a kidney stone, notes MedicineNet. If the stone does not pass on its own, you may undergo lithotripsy, a procedure in which shock waves break up the stone into smaller pieces that pass more easily. This procedure lasts up to an hour and can cause moderate pain, so you made receive sedation or light anesthesia, states Mayo Clinic. Alternatively, a doctor may pass a ureteroscope into the ureter or kidney to remove or break up the stone. Very large stones require surgical removal through a small incision in your back.
