Causes And Risk Factors
Kidney stones form when certain substances in the urine turn into crystals. These substances are often salts, but uric acid or other minerals sometimes form stones too:
- 80% of people with kidney stones have stones,
- 5 to 10% have uric acid stones, and
- 10% have stones made up of the mineral struvite.
Stones of any other substances are rare.
Usually, these substances are dissolved in the urine. But some medical conditions cause their concentration in the urine to rise, resulting in crystals. For instance, if the parathyroid glands are overactive, the level of in the urine will rise. Gout increases the level of uric acid. Sometimes, but rarely, the excess levels are genetic. This is the case if the stones are made of the amino acid cystine, for example.
Nutrition is a factor too: Some foods, such as rhubarb, contain high levels of oxalic acid. Offal may increase uric acid levels. These higher levels can result in kidney stones. The concentration of substances that can potentially form stones also increases if we don’t drink enough fluids.
One other cause might be a lack of substances that usually prevent the formation of stones in the urine, the main one being citrate. A citrate deficiency may result from chronic diarrhea, for example.
Certain medications can create favorable conditions for kidney stones, too either because they form crystals in the urine themselves or because they change the composition of the urine.

Kidney Stone Undescended No Symptoms
A kidney stone starts as tiny crystals that form inside the kidney where urine is made. Most kidney stones enlarge to about 1/8 to 1/4 inch in size before leaving the kidney and moving toward the bladder. There are 4 types of kidney stones. Eighty percent are calcium stonesmostly calcium oxalate but also some with calcium phosphate. The other 3 types include uric acid stones, struvite stones , and rarely, cystine stones.
When the stone breaks free and starts to move down the ureter it often causes sharp, severe back and side pain, often with nausea and vomiting. When the stone reaches the bladder, the pain stops. Once in your bladder, the kidney stone may pass through the urethra while you are urinating . Or, it may break into such small fragments that you dont notice it passing.
Your kidney stone is still inside the kidney. There is no way to predict how long it will be before it breaks free and causes any symptoms. Most stones will pass on their own within a few hours to a few days . You may notice a red, pink, or brown color to your urine. This is normal while passing a kidney stone. A large stone may not pass on its own and may require special procedures to remove it. These procedures include:
Lithotripsy. This uses ultrasound waves to break up the stone.
Ureteroscopy. A thin, basket-like instrument is pushed through the urethra and bladder to pull out the stone.
Direct surgery through the skin

What Are The Symptoms Of Kidney Stones
“A kidney stone is a hard mass that’s made up of minerals , certain salts and other byproducts. They can form when these substances accumulate in the area of your kidneys where urine is produced,” explains Dr. Kannady.
Kidney stones can be as small as the point of a pen or as large as a ping pong ball.
“Typically, a person doesn’t start noticing the symptoms of a kidney stone until it moves from the kidney into the ureter, which is the tube that carries urine from your kidney to your bladder,” Dr. Kannady adds.
Kidney stone symptoms include:
- Sharp pain in the lower abdomen, typically on one side
- A burning sensation or pain while urinating
- Urinating frequently
- Feeling like you’re urinating incompletely or in small amounts
- Urine that is brown, red or pink, which indicates the presence of blood

When Surgery Is Necessary
If you think you might have a kidney stone, you should see your doctor as soon as possible. If youre found to have one, your doctor can help you determine whether to try to pass the stone naturally, take medication, or get the stone surgically removed.
In some circumstances, your doctor might recommend immediate surgical removal without a waiting period. This will usually be because the stone is too big to pass naturally or is blocking urine flow. If the stone is blocking the flow of urine, it can lead to an infection or renal damage.
In other circumstances, your doctor might recommend waiting to see if you can pass the stone on your own. You should check in with your doctor often during this time to see if anything is changing, especially if you have new symptoms.
During the waiting period, your doctor might recommend surgery if the stone continues to grow, youre having unmanageable pain, or you develop signs of infection, such as a fever. Infection, fever, kidney damage, intractable pain, or intractable vomiting are all indications for immediate surgery.

Take Steps To Bypass Kidney Stones
Even though kidney stones can be common and recur once youve had them, there are simple ways to help prevent them. Here are some strategies that can help:
1. Drink enough water. A 2015 meta-analysis from the National Kidney Foundation found that people who produced 2 to 2.5 liters of urine daily were 50% less likely to develop kidney stones than those who produced less. It takes about 8 to 10 8-ounce glasses of water daily to produce that amount.
2. Skip high-oxalate foods. Such foods, which include spinach, beets, and almonds, obviously raise oxalate levels in the body. However, moderate amounts of low-oxalate foods, such as chocolate and berries, are okay.
3. Enjoy some lemons. Citrate, a salt in citric acid, binds to calcium and helps block stone formation. “Studies have shown that drinking ½ cup of lemon juice concentrate diluted in water each day, or the juice of two lemons, can increase urine citrate and likely reduce kidney stone risk,” says Dr. Eisner.
4. Watch the sodium. A high-sodium diet can trigger kidney stones because it increases the amount of calcium in your urine. Federal guidelines suggest limiting total daily sodium intake to 2,300 milligrams . If sodium has contributed to kidney stones in the past, try to reduce your daily sodium to 1,500 mg.

Reducing Kidney Stone Risk
Drinking enough fluid will help keep your urine less concentrated with waste products. Darker urine is more concentrated, so your urine should appear very light yellow to clear if you are well hydrated. Most of the fluid you drink should be water. Most people should drink more than 12 glasses of water a day. Speak with a healthcare professional about the right amount of water that’s best for you. Water is better than soda, sports drinks or coffee/tea. lf you exercise or if it is hot outside, you should drink more. Sugar and high-fructose corn syrup should be limited to small quantities.
Eat more fruits and vegetables, which make the urine less acid. When the urine is less acid, then stones may be less able to form. Animal protein produces urine that has more acid, which can then increase your risk for kidney stones.
You can reduce excess salt in your diet. What foods are high in salt? Everyone thinks of salty potato chips and French fries. Those should be rarely eaten. There are other products that are salty: sandwich meats, canned soups, packaged meals, and even sports drinks.
Some herbal substances are promoted as helping prevent stones. You should know that there is insufficient published medical evidence to support the use of any herb or supplement in preventing stones.
