About 1 out of every 11 people in the United States will get a kidney stone. Stones are more common in men, people who are obese, and those who have diabetes 1.
You might not notice anything is amiss until the stone moves into your ureter — the tube that urine travels through to get from your kidney to your bladder. Kidney stones are typically very painful. Most stones will pass on their own without treatment. Here are eight signs and symptoms that you may have kidney stones. Kidney stone pain — also known as renal colic — is one of the most severe types of pain imaginable 2. The pain is intense enough to account for more than 1 million visits to emergency rooms each year 3.
Usually the pain starts when a stone moves into the narrow ureter. This causes a blockage , which makes pressure build up in the kidney. Kidney stone pain often starts suddenly.
As the stone moves, the pain changes location and intensity. Pain often comes and goes in waves, which is made worse by the ureters contracting as they try to push the stone out. Each wave may last for a few minutes, disappear, and then come back again. It may radiate to your belly and groin area as the stone moves down through your urinary tract.
Even a little stone can be painful as it moves or causes a blockage. Your doctor might call this dysuria. The pain can feel sharp or burning. Sometimes you can have an infection along with the stone. Needing to go to the bathroom more urgently or frequently than usual is another sign that the stone has moved into the lower part of your urinary tract. You may find yourself running to the bathroom, or needing to go constantly throughout the day and night.
Urinary urgency can also mimic a urinary tract infection symptom. How long do kidney stones take to pass? Large stones may need other types of intervention, such as shock wave lithotripsy SWL , ureteroscopy, or percutaneous nephrolithotomy PCNL. SWL involves the use of ultrasound waves to break the stone into smaller pieces to make it easier to pass. They will then use laser energy to break up the stone. PCNL involves passing a long, thin instrument through the back and into the kidney, where it can break up or remove the stone using laser energy.
This procedure requires general anesthesia. There may be a risk of complications, such as an infection, after removing a large kidney stone. A doctor should explain the possible complications beforehand so that if any develop, a person can recognize the signs.

If the stone gets stuck somewhere and blocks the flow of urine, it causes pain. Most stones occur when calcium combines with oxalate. Stones can also form from uric acid, which is a byproduct of protein metabolism. Drink plenty of water: Drinking extra water dilutes the substances in urine that lead to stones.

It may help to include some citrus beverages, like lemonade and orange juice. The citrate in these beverages helps block stone formation.
