Does Potassium Citrate Reduce Kidney Stones

Why It Is Important To Do This Review

Does potassium citrate prevent future kidney stones? / Kidney Stone Diet with Jill Harris

Various studies have demonstrated that citrate excretion is significantly lower in stone formers than in normal controls and citrate supplementation increases the urinary citrate level. A number of nonrandomised studies have demonstrated a beneficial effect of citrate salts therapy in patients with kidney stones. demonstrated superiority of potassium citrate’s over sodiumpotassium citrate. The European Association of Urology Guidelines on Urolithiasis recommends the use of citrate in hypocitraturia. However, the evidence base for this recommendation is limited.

There is no consensus on the best formulation to treat recurrent kidney stone disease. This uncertainty warranted a systematic review to synthesise all available evidence on the efficacy, safety and acceptability of products containing citrate salts to assist people with stone disease and to reduce recurrence by creating good evidencebased treatment decisions.

Kidneys Filter And Reabsorb Citrate

In one published study,;concentration of citrate in blood is about 80 170 micromolar. A recent review places it at 120micromoles/liter.;If we use 120 micromoles/liter;as a reasonable average, and a common value for glomerular filtration of 120 milliliters/minute, the filtration of citrate is about 21;millimoles a day. Of this about 1; 4;millimoles appear in the urine, the rest being reabsorbed by the kidney cells. So the fraction of filtered citrate excreted is about 5;to 20%, and regulation of this fraction controls the amount of citrate in the urine.

Try To Avoid Soft Drinks

Many soft drinks like cola contain phosphoric acid , which may possibly increase the likelihood of kidney stones forming. There has only been one high-quality study on the question of whether not drinking soft drinks also lowers the risk of developing more kidney stones. In the study, 500 men were advised to drink fewer soft drinks. On average, they lowered their consumption to under 100 milliliters per day that’s less than half a glass. Their risk of kidney stones dropped in comparison to the group of men who didn’t change their drinking habits. The study showed the following after three years:

  • 41 out of 100 men who drank as many soft drinks as before developed another kidney stone.
  • 34 out of 100 men who drank fewer soft drinks developed another kidney stone.

In other words, drinking fewer soft drinks prevented the development of further kidney stones in 7 out of 100 men. Some men dropped out of the study early possibly because they found it difficult to change their drinking habits.

Herbs And Supplements To Use Only With Caution

According to some, but not all research, use ofvitamin C supplements can slightly raise levels of oxalate in the urine,40,41,53 which could, in turn, increase risk of kidney stones. However, large-scale observational studies have found that people who consume large amounts of vitamin C have no increased risk or even a decreased risk of kidney stone formation.42-44 Nonetheless, it seems that in certain people, high vitamin C intake can lead to a rapid increase in urinary oxalate, and in one case stones developed within a few days.45 The bottom line: People with a history of kidney stones should probably limit vitamin C supplements to about 100 mg daily.46

Some evidence hints that excessive consumption of phosphorus in the form of soft drinks might increase kidney stone risk, but study results are contradictory, and if there is an effect, it appears to be small.62-64

As noted above, regular consumption of grapefruit juice may significantly increase risk of stones.17

What Are Struvite Stones

Potassium Citrate 99mg 100% Vegetar (end 1/10/2017 12:15 PM)

Struvite stones are caused by infections in the upper urinary tract. A kidney stone is a hard object that is made from chemicals in the urine. After formation, the stone may stay in the kidney or travel down the urinary tract into the ureter. Stones that don’t move may cause significant pain, urinary outflow obstruction, infection, or other health problems.

Oj Better Than Lemonade

In the study, researchers compared the effects of orange juice and lemonade in preventing recurrent kidney stones. Both juices contain comparable citrate levels.

Thirteen volunteers, some with a history of kidney stones and some without, participated in the three-phase study.

In random order, the participants drank approximately 13 ounces of either distilled water, orange juice, or lemonade three times a day with meals for one week, with a three-week interval before moving to the next phase. They also followed a special diet as recommended for preventing recurrent kidney stones.

The results showed that orange juice increased levels of citrate in the urine and decreased urine acidity, which reduced the risk of kidney stones. But lemonade did not have the same effect.

“Orange juice could potentially play an important role in the management of kidney stone disease and may be considered an option for patients who are intolerant of potassium citrate,” says researcher Clarita Odvina, MD, assistant professor of internal medicine at the University of Texas Southwestern Medical Center at Dallas, in a news release.

The results appear in the Clinical Journal of the American Society of Nephrology. Researchers say this was a small study and further research is needed to evaluate the role of orange and other citrus juices in preventing kidney stones.

The study was supported by research grants from NIH.

We Do Need A Trial Of Citrate For Calcium Phosphate Stone Formers

I do not know how often this must be said. Calcium phosphate stone formers must lurk in each of the trials I have reviewed, but I do not know their outcomes. One trial insisted stones be at least >50% calcium oxalate. That means perhaps a few had considerable phosphate is stones.

Calcium phosphate crystal formation is sensitive to urine pH whereas calcium oxalate stone formation will not be. The reason is that calcium phosphate supersaturation requires divalent phosphate be present, and the pKa for the second proton is about 6.8. Citrate salts can raise urine pH, so they can raise supersaturation with respect to calcium phosphate salts. On the other hand, citrate is an inhibitor of crystallization both because it is calcium binding and because it directly affects calcium crystal growth.

Calcium Oxalate And Calcium Phosphate Stones

Calcium stones are the most common type of kidney stones, and can be either calcium oxalate or calcium phosphate. As mentioned, good hydration is important to prevent calcium stones. It may be surprising, but results of a randomized clinical trial show that people with calcium kidney stones should not cut back on dietary calcium. In fact, they should consume the recommended daily allowance of calcium . Why? Calcium binds to oxalate in the intestine and prevents its absorption through the gut, so there is less in the urine to form stones. Ideally, calcium should come from food. Talk with your doctor before taking calcium supplements, and increasing fluid intake might be beneficial depending on how much calcium you take.

Foods high in oxalates can increase the amount of oxalate in the urine. Consume these in moderation.

Calcium phosphate stones are less common than calcium oxalate stones. Causes include hyperparathyroidism , renal tubular acidosis , and urinary tract infections. It is important to understand if one of these conditions is behind the formation of calcium phosphate stones.

Good hydration can help prevent recurrence of calcium stones. In addition, thiazide diuretics such as hydrochlorothiazide can help the kidney absorb more calcium, leaving less of it in the urine where it can form stones. Potassium citrate is another medication that can bind to calcium and help keep calcium oxalate and calcium phosphate in the urine from forming into stones.

Why Are Potassium Citrate Pills An Alkali Load

In the citric acid cycle citrate is metabolized as citric acid, meaning that 3 protons are taken up from blood with each molecule. Removing protons is identical to adding alkali. Typical dosing is about 20 40 mEq of potassium salt daily, but the amount can vary widely.

Commercial potassium citrate contains 1080 mg of the compound in a 10 mEq pill. Typically the potassium citrate salts have a potassium on each of the three anion sites on the citrate molecule.;The MW of citrate anion is 189.1.;Urocit K, a common commercial version, is a crystalline monohydrate salt;so it has a MW of 3×39 + 189.1 + 18 for the one water molecule, or 324.1 in all. Given 324.1 for 3 mEq of base, the 10 mEq tablet contains 10/3 x 324.1 or 1080 mg.

Should I Cut Out All Foods That Have Oxalate Or Calcium


No, this is a common mistake. Some people think that cutting out all foods that have oxalate or all foods with calcium will keep stones from forming. However, this approach is not healthy. It can lead to poor nutrition and can cause other health problems. A better plan? Eat and drink calcium and oxalate-rich foods together during a meal. Doing this helps oxalate and calcium bind to one another in the stomach and intestines before reaching the kidneys, making it less likely for kidney stones to form in the urine.

Description Of The Condition

Kidney stones remain a public health problem around the world irrespective of geographical, cultural or racial backgrounds, with an incidence of approximately 0.1% to 0.3%. The lifetime risk is estimated to be between 10% and 20% in the Western world, but can be as high as 20% to 25% in the Middle East. Stone disease typically affects men two times more commonly than women and peak incidence is in the fourth to sixth decades of life . Recent studies reported that the male:female ratio of patients with stones altered from 1.6:1 to 1.2:1 ,1.7:1 to 1.3:1 . Between the mid1970s and the mid1990s, the prevalence of stone disease increased from 3.2% to 8.8% in the USA . The stone recurrence rate without treatment is approximately 10% at one year, 33% at five years, 50% at 10 years, and 75% at 20 years . Following first recurrence, the subsequent relapse risk is increased with a shortened time interval between recurrences .

Most stones are composed of calcium salts . The remainder are noncalcium stones such as struvite , uric acid , cystine , or other substances . Kidney stone formation is based on supersaturation of urinary salts and crystal retention in the urinary tract. Urinary Inhibitors and promoters are involved in the process and deficiency of inhibitors or abundance of promoters in the urine thought to predispose to stone disease .

What Are Side Effects Of Potassium Chloride

Highly acidic urine can increase the risk of uric acid kidney stones and make passing them more painful.

High amounts of acid in the urine also encourage the kidneys to reabsorb citrate rather than excrete it. Citrate is a compound that can help flush out calcium-based stones, as well as impair their growth.

Highly acidic foods include:

According to the National Kidney Foundation, almost 1 in 10 people in the United States develop a kidney stone during their lifetime. The risk is around 19% for men and 9% for women.

Most men experience their first kidney stone after the age of 30 years.

How To Dissolve Kidney Stones

How Kidney Stones Form

If you have ever passed a kidney stone, you most likely would not wish to go through this excruciating process again; in fact, you probably would not wish it on your worst enemy. Kidney stones are common in both males and females and can strike again in half of those who develop it, usually within 5 to 7 years if preventive measures are not taken.

Kidney stones form when substances like oxalate, calcium, and uric acid become overly concentrated and create crystals in the kidneys. Those crystals then grow larger and form kidney stones. About 75 percent of all kidney stones are calcium oxalate stones.

After kidney stones develop, they can dislodge and pass down to the ureter, blocking urine flow. This can lead to periods of severe pain and discomfort, including pain in one side of the body between your stomach and your back. At times, pain can be accompanied by blood in the urine, nausea, and vomiting.

As the stones travel down the ureter to the bladder, they may result in bladder pressure, groin pain, or frequent urination. If you experience any of these symptoms, you should speak to your doctor. He/she will probably carry out a urinalysis and renal ultrasound, abdominal x-ray, or CT scan to determine if you have kidney stones and confirm their size and number.

Diagnosis of Kidney Stones

If your doctor suspects that you have a kidney stone, he/she may carry out diagnostic tests and procedures, such as:

1. Blood test:

2. Urine test:

3. Imaging:
