Gout and kidney stones can occur together, but having gout does not mean you will develop stones. It also does not mean that every stone you develop will be made of uric acid.
The connection involves uric acid handling, urine concentration, and urine acidity. These factors need separate assessment: a blood uric acid result cannot identify the composition of a kidney stone.
If you have both conditions, stone analysis and appropriate urine testing can help your clinician build a prevention plan that addresses your actual risks.

How Are Gout and Kidney Stones Connected?
Gout involves monosodium urate crystals in and around joints. Uric acid stones form within the urinary tract under conditions that allow uric acid to crystallize.
They are related problems, but joint crystals do not travel from your toe into your kidneys.
For uric acid stones, persistently acidic urine is particularly important. Low urine volume and, in some people, increased urinary uric acid also contribute.
Blood urate, urinary uric acid, and urine pH are different measurements. A prevention plan may need to address more than the blood result alone.
For background, read what uric acid is.
Does Having Gout Mean Your Stone Is a Uric Acid Stone?
No. People with gout can develop calcium-containing stones or stones with mixed components.
This distinction matters because treatments are not interchangeable. A treatment intended to dissolve a uric acid stone will not dissolve a calcium oxalate stone.
If you pass a stone, ask how to collect and submit it for laboratory analysis. Do not identify its composition from color, shape, or an online photograph.
| Finding | What it can—and cannot—tell you |
|---|---|
| High blood uric acid | Relevant to gout, but does not identify stone composition |
| Acidic urine | Supports assessment of uric acid stone risk, but does not prove a stone is present |
| Imaging | Shows features such as stone size, location, and possible obstruction |
| Stone analysis | Identifies the material in the submitted stone |
| A 24-hour urine collection | Helps identify urinary factors that may contribute to recurrence |
Symptoms That Need Assessment
Kidney stones may cause sharp pain in the side or back, sometimes moving toward the lower abdomen or groin. Pain can come in waves.
Other symptoms can include blood in the urine, painful urination, nausea, or vomiting. These symptoms also have other possible causes.
Seek urgent medical care if you have suspected stone pain with fever or chills, cannot urinate, have uncontrolled pain, or cannot keep fluids down.
Fever with a urinary blockage can represent a serious infection. Do not wait for a home remedy to work.
Having gout should not lead you to dismiss abdominal or back pain as another gout flare.
What Tests Help Guide Prevention?
Your clinician may use blood tests, urine tests, and imaging to investigate the stone and check kidney function.
After the immediate episode, stone analysis and a metabolic assessment help determine whether further testing is needed. A detailed assessment often includes 24-hour urine collections, particularly for people at higher risk of recurrence.
Follow the laboratory’s collection instructions carefully. An incomplete collection can make results difficult to interpret.
Useful questions include:
- What type of stone did I have?
- Was it causing a blockage?
- Do I need a 24-hour urine assessment?
- Is urine acidity part of my risk?
- How will we check whether prevention is working?

If you are comparing paid gout guides, read the seller’s information here. A general gout programme should not replace stone analysis, imaging, or treatment of a urinary obstruction.
Can Uric Acid Stones Be Dissolved?
Some uric acid stones can be dissolved by medically supervised treatment that makes urine less acidic.
Medicines used for this purpose may include potassium citrate or, in selected circumstances, sodium bicarbonate. Treatment requires an appropriate urine pH target and monitoring; making urine excessively alkaline can create other stone risks.
This approach depends on the likely stone composition and the clinical situation. A blocked or infected urinary system may need urgent drainage or another procedure.
Do not self-prescribe potassium citrate or baking soda. Kidney function, potassium levels, sodium intake, and other medicines affect what is suitable.
“Uric acid stones can sometimes dissolve” does not mean that every stone can be safely managed at home.
Does Allopurinol Prevent Kidney Stones?
Allopurinol lowers uric acid production and is used for gout. It may also be prescribed for selected stone-formers when their findings support its use.
However, it does not automatically correct persistently acidic urine. Someone taking allopurinol may still need a separate stone-prevention plan.
Do not increase your dose because of stone symptoms. Ask your clinician how the gout prescription fits with your urine results and stone type.
Practical Prevention When You Have Gout and Stones
Agree on a fluid plan
Adequate fluid intake helps keep urine less concentrated. Spread drinks through the day rather than trying to consume a large amount at once.
Your clinician can set a suitable intake or urine-output goal. If you have heart failure, advanced kidney disease, or a prescribed fluid restriction, generic advice to drink several extra litres may be inappropriate.
Do not force large volumes of water during severe pain or suspected obstruction.

Adjust food choices to the stone type
Limiting excessive animal protein may be relevant to uric acid stone prevention. Sodium reduction is also important for many calcium stone-formers.
Do not automatically eliminate calcium from food. Appropriate dietary calcium can be part of calcium oxalate stone prevention, while supplements need individual review.
A dietitian can help reconcile stone advice with gout, diabetes, or kidney-related dietary needs.
Avoid extreme dietary changes
A very restrictive diet may be difficult to maintain and may not address the factor driving your stones.
Use your results to guide changes rather than avoiding every food mentioned on a generic stone list. See the gout diet guide for gout-specific food considerations.
Follow through with monitoring
Feeling better after a stone episode does not establish that recurrence risk has been addressed.
Keep the recommended follow-up appointments and tests. Bring all prescriptions and supplements to the review so your clinicians can coordinate the two treatment plans.
Frequently Asked Questions
Can I have a uric acid stone without gout?
Yes. Urine conditions can favor uric acid stones even without a history of gout attacks.
Does a normal blood uric acid result rule out uric acid stones?
No. Urine acidity and concentration matter, and the blood result alone cannot exclude them.
Will lemon water dissolve a uric acid stone?
It should not be treated as a reliable substitute for prescribed urine-alkalinizing treatment. Whether a stone can dissolve requires assessment and monitoring.
Does controlling gout guarantee that stones will stop?
No. Good gout control is valuable, but stones can involve other urinary risk factors and different materials.
Should I stop calcium-containing foods?
Not automatically. Advice depends on stone type and your nutritional needs. Discuss calcium supplements separately with your clinician.
Do I need surgery for a kidney stone?
Not always. Management depends on size, location, composition, symptoms, obstruction, and infection. Some stones pass, some uric acid stones may dissolve with treatment, and others require a procedure.
