Can Kidney Stones Be Dissolved?

First things first. Can kidney stones be dissolved in the first place? Answer: it depends on the type of kidney stone you have.

If you don’t know what kind of kidney stone you have, a 24-hour urine test will give you a pretty good idea. An analysis of the stone itself is the only way to confirm the type of kidney stone you had.

Title: Can this type of kidney stone dissolve? No: calcium oxalate & calcium phosphate. Maybe: uric acid

How to Dissolve Calcium Oxalate Kidney Stones

Calcium oxalate is the most common type of kidney stone. About 80% of kidney stones are calcium oxalate. (1)

Unfortunately, calcium oxalate kidney stones cannot be dissolved. Once a calcium oxalate kidney stone has formed, you have to pass it, or have it removed by a urologist.

There are a handful of studies that have found ways to dissolve calcium oxalate kidney stones outside the body. Scientists can dissolve calcium oxalate kidney stones in petri dishes with a variety of chemicals. (2) (3) However, no studies have found a way to dissolve calcium oxalate kidney stones in the body.

It is hard to translate these petri dish studies to kidney stones in real humans. Remember, eating or drinking something is very different than putting that something directly on a kidney stone to dissolve it. When you consume a food or supplement, it has to be absorbed in the intestines, transported through the blood, metabolized by the liver, repackaged and excreted in the urine. All of these processes dramatically change food from the state you eat it in. It is also important to consider if enough of what you consume makes it to your urine, where it could dissolve kidney stones.

How to Dissolve Calcium Phosphate Kidney Stones

Similar to calcium oxalate kidney stones, there is no way to dissolve calcium phosphate kidney stones.

How to Dissolve Uric Acid Kidney Stones

Good news! You can dissolve uric acid kidney stones fast.

Many uric acid kidney stones can be dissolved by a medication called potassium citrate. The goal of this therapy is to reduce urine acid levels (aka, increase your urine pH). (4) (5) For most people, a urine pH of at least 6.0 is the goal to dissolve uric acid kidney stones.

Your doctor may even ask you to to test your urine pH at home using basic pH testing strips*. There are also fancier options* that also measure urine ketones, glucose, protein and a number of other things. Testing your urine pH can help make sure your medication is working to lower urine acid.

How Fast Can you Dissolve Uric Acid Kidney Stones?

The time it takes to dissolve uric acid kidney stones depends on the size and composition of your kidney stone, and urine pH.

One study found the average time to dissolve uric acid kidney stones was 3 months. (4) Another study found it took 6 weeks for uric acid kidney stones to dissolve. (5) Either way, this timeframe is a relatively fast way to dissolve kidney stones!

Natural Remedies to Dissolve Uric Acid Kidney Stones Fast

If you prefer to avoid medication, there are ways to reduce urine acid and help dissolve uric acid kidney stones naturally.

Here are some things you can do to help dissolve uric acid kidney stones:

  • Use the power of food! What you eat can change the pH of your urine. Eat more foods with a negative acid load, and fewer foods with a positive acid load to help increase urine pH. For most people, this boils down to less animal protein and more fruits and vegetables. Learn more about dietary acid load.
  • Lemon juice. But, you need a lot of it! A typical dose of potassium citrate is 20mEq. A 1/2 cup of lemon juice has the same amount of alkali as 20mEq dose of potassium citrate. Squeezing a wedge of lemon into your water is probably not going to cut it.
  • Get potassium citrate from drinks! Crystal Light Lemonade* is surprisingly high in potassium citrate. One liter has the same amount of alkali as 20mEq of a potassium citrate pill.
  • Try a drink powder. I know these are a bit more like medications. However, if you want to avoid pills, Moonstone* and Litholyte* can help reduce acid in your urine.
How to increase urine pH. Eat at least 5 servings fruits and vegetables per day. Enjoy animal protein in small portions & less often.

Disclaimer: Although all of these natural remedies can reduce urine acid, these remedies have not been proven to be as effective as medication. They may not reduce acid levels enough to dissolve your kidney stones. As your doctor what is best for you!

Supplements & Foods to Dissolve Kidney Stones Fast

There are many supplements that claim to dissolve kidney stones fast. Very few of these are backed by research.

In fact, a study found that two-thirds of dietary supplements that claim to treat or prevent kidney stones contain ingredients with conflicting or no scientific evidence to support their claims. (6)

Here are some supplements and foods that claim to dissolve or help with kidney stones. NONE of these are backed by quality research. I do not recommend them for kidney stone prevention or treatment.

Also, supplements are not regulated in the United States, and could cause harm. Always let your doctor or dietitian know about any nutritional or herbal supplements you take.

What You CAN Do About Kidney Stones

For most people, there is no good way to dissolve kidney stones fast. I truly wish I could give you a more positive news!

However, there is a lot you can do to prevent kidney stones! If you have had one kidney stone, you have up to a 50% chance of having another stone at some point in your life. (7) So, kidney stone prevention is very important!

Kidney stone prevention is different for everyone. There is no single “kidney stone diet” that is for everyone. Not even one diet for people with the same type of kidney stone.

Instead, nutrition for kidney stones must be personalized to your 24-hour urine test results. This test will tell you and your doctor the cause of your kidney stone, to make sure your treatment will be effective.

Here is some general information about how to prevent calcium oxalate and uric acid kidney stones. Always ask your Registered Dietitian what is best for you!

Happy Eating!

    I have a 5mm Kidney stone in my right mid kidney now along with muiltable small ones and some in my left kidney as well. Uric Acid level is 7.7 mg/dl , Calcium is 9,4 mg/dl. this is about the 40 time i’ve had stones since 1984. I’ve had it all Lithotripsy and everything else done. Been told that my stones are made up of calcium / uric aid. What i had learn about stones i should be a urologist. I live in southern Lousisana and work outside, swet like a mule, drink water all day, One cup of coffee per day, No soft drinks, Drink ice tea at dinner. Eat fish, chickhen, salads with some spinach,( not every day). I need help. doctors have been telling me to stop eatting this and drinking that. I do it and still get Stones. I’m so tired of this merry go round. Please Please help. i can sent you my blood charts and CT scans

      Hi Robert. OH my goodness. I’m so sorry you’ve been dealing with stones for so long. I can’t imagine! I would love to help you come up with a TARGETED, effective plan to prevent more stones. You can work with me in Kidney Stone Nutrition School – or schedule an appointment with one of our kidney stone dietitians. You can learn about both options here. Please don’t hesitate to reach out with questions!

  2. Thank you for your WONDERFUL service and assistance. One question: there is a procedure to bombard an existing kidney stone with sonic waves that is non-invasive and is supposed to break up the stone into small granueles that can readily pass through the system. Do you have thoughts on this procedure? Is it safe? recommended?

    Thank you, again.

    1. Melanie Betz MS, RD, CSR, CSG

      You are so welcome! This is a MUCH better question for a urologist. This is their expertise (nutrition is mine!). I can say this is a VERY common procedure to get rid of those kidney stones!

    2. If the stone is in the kidney, sometimes this procedure, lithotripsy, will help break up the stone fairly safely, however, if it is in your ureter it is too dangerous. Try StoneBreaker…Chanca Piedra. It works for me.

    3. I had this done several years ago for a large kidney stone. It left me a bit sore, but it was much less invasive than the surgery I had to have later, and the stone was broken up and caught in the strainer I was given to urinate in, after which no signs of the stone were found. I can’t speak for everyone, but it was much more pleasant than surgery, with a MUCH faster recovery time.

    4. I have had this done ten times already throughout the past maybe 7 years. It is very safe, and there is no discomfort involved. After the stones are crushed you just have to strain your urine for some weeks so the doctor can have them checked to see what kind of stones you are passing. It’s a good way to get rid of stones with no needing to fret.

    1. Melanie Betz MS, RD, CSR, CSG

      Thank you for sharing. I am aware of this and similar studies. There is not enough data in humans to show that consuming ACV can prevent stones for me to recommend it at this time. But, it is something to watch.

  3. i’ve been put on a low calcium oxalate diet for a kidney stone. Can i have broccoli, olive oil, kale, spinach, peas, Oikos high protein yogurt?

    thank you, i’m very frustrated and hungry!

    1. Melanie Betz MS, RD, CSR, CSG

      Hi Donna! Thank you SO much for your comment. I’d question your doctor’s advice for a low calcium diet for kidney stones. This is actually very outdated and dangerous advice. We now know that a low calcium diet significantly INCREASES the risk of calcium oxalate stones. This article about all aspects of calcium oxalate stone nutrition that might apply to you (ultimately, nutrition has to be personalized to your 24 hour urine test results) will be helpful. Also, this article about calcium specifically will be helpful. I’d love to help you understand exactly what you should eat for stone prevention – I help people do this in Kidney Stone Nutrition School!

  4. Thank you for this incredible resource! I have lots of digestive issues and so my diet is already quite restricted. I am pretty strict about high oxalate foods because of my history with kidney stones – passed two, ultrasound shows several tiny ones still lurking. 🙁 I’m inspired by the calcium intake connection you mention. I’m wondering how important it is that the calcium be ingested WITH the meal…all that calcium can be constipating for some of us! So frustrating…any suggestions??

    1. Melanie Betz MS, RD, CSR, CSG

      Hi Judy! I’m so glad this was helpful! This article will help you with your calcium piece. For “how important it is to pair calcium with oxalate” – it truly depends on your 24 hour urine test. I can’t say what is best for you without looking at those results. For constipation, it can be helpful to increase your dairy slowly to help your body adjust. Also, to get plenty of water (which is critical for stones anyway!) and fiber (which can be difficult on a restrictive low oxalate diet, which is one of the MANY reasons I always want to make absolutely SURE that someone NEEDS a low oxalate diet). I have lots of tips for combating constipation in the summer edition of Stop Kidney Stones From Your Kitchen and in Kidney Stone Nutrition School!

  5. Hello I’m 40yrs old African American female. 1 1/2 ago I was diagnosed with stage 3 kidney disease.

    1. Melanie Betz MS, RD, CSR, CSG

      Hi Myeisha! So good to “meet” you! I think this article about how food can impact acid/CO2 levels in your body will be helpful to you. Ultimately, nutrition is truly different for every single person. I’d recommend asking for a renal dietitian referral to see what is best for you!

    Hi, very informative site. A minor correction on a typo error of listed non official possible kidney stone solutions. It is “chanca piedra”. Chanca comes, probably from quechua. In Peru, it is a very well known weed, boiled, and water drunk to “chancar” or mush the stones. I have tried the herb (works well) and would not take the capsules/pills sold on line since it is not medically regulated. The tea you can make it weak and, play it by ear, to increase herb use.

  7. This was a great post. When I had to get more citrate into my husbands diet, I cannot tell you how hard it was to find out how muck citrate was in K.Cit pill vs lemon juice vs Crystal Light (which I try to avoid due to artificial sweeteners in latge amounts often). Took me forever, you would think I wanted the combination to Fort Knox! I hope many other people find it helpful.

    1. Melanie Betz MS, RD, CSR, CSG

      Thank you so much Carol! I’m glad you found the article helpful. Good luck with getting in that citrate!
