Kidney stones do not all require the same treatment. Some small stones pass through the urinary tract without a procedure, while larger stones may need to be broken apart or removed.

The right approach depends on several factors, including:

• The stone's size and location

• Whether urine flow is blocked

• The severity of pain

• Whether infection is present

• Kidney function

• The stone's composition and density

• Previous kidney stones and other medical conditions

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), treatment options include observation, pain-relieving medicines, shock wave lithotripsy, ureteroscopy and percutaneous nephrolithotomy (PCNL).

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides kidney evaluation and medical management, with appropriate coordination for urological procedures when stone removal is required.

1. Observation: When a Kidney Stone May Pass Naturally

Some small kidney stones can pass through the urinary tract without surgery. A doctor may recommend observation when the stone is likely to pass and there are no complications requiring immediate treatment.

During observation, the treatment plan may include:

• Appropriate pain relief

• Monitoring symptoms and urine output

• Following individualized fluid advice

• Taking prescribed medicines when indicated

• Follow-up imaging or tests to confirm whether the stone has passed

A stone's size and location influence the likelihood of natural passage. A small stone in the ureter may pass, while a larger stone or one causing persistent obstruction may require active treatment.

Important: Observation should not mean ignoring the stone. Follow-up is needed to ensure it has passed or is not damaging kidney function.

2. Medicines for Kidney Stones

Medicines can help with pain, nausea and, in selected cases, stone passage. However, no single tablet works for every stone.

Pain Relief Medicines

A clinician may recommend pain medication based on the patient's symptoms, kidney function and other medical conditions.

Some anti-inflammatory painkillers can be effective for renal colic, but they may be unsuitable for people with chronic kidney disease, dehydration, certain heart conditions or other risks. Do not take them without checking whether they are safe for you.

Medicines That May Help a Stone Pass

For selected ureteral stones, a doctor may prescribe a medicine that relaxes the ureter and may improve the chance of passage. These medicines are not suitable for every stone, and their benefit depends on factors such as stone size and location.

Medicines That Dissolve Certain Stones

Some uric acid stones may be dissolved through medically supervised urine alkalinization. This approach does not work for most common calcium-based stones and requires monitoring.

Do not take stone medicines, antibiotics or herbal remedies without medical advice. Treatment should be based on the suspected stone type, test results and individual health risks.

3. Fluid Intake and Home Care

Home care can support recovery when a clinician confirms that conservative treatment is appropriate. It cannot replace urgent treatment for an infected or severely obstructed urinary tract.

Drink an Appropriate Amount of Water

Adequate fluid intake helps prevent many kidney stones from forming. However, drinking excessive water does not reliably force an existing stone through an obstruction.

If you have advanced kidney disease, heart failure, reduced urine output or a prescribed fluid restriction, ask your clinician how much you should drink.

Follow the Prescribed Pain Plan

Take medicines only as directed. If pain remains severe despite treatment, seek medical reassessment rather than repeatedly increasing doses.

Collect the Stone if Advised

If a stone passes, your clinician may ask you to collect it for laboratory analysis. Knowing its composition can help guide prevention.

Avoid Unproven Remedies

Apple cider vinegar, herbal mixtures, kidney cleanses and other online remedies have not been established as reliable treatments for all kidney stones. Do not delay appropriate treatment while trying them.

4. Shock Wave Lithotripsy (ESWL)

Extracorporeal shock wave lithotripsy (ESWL) uses shock waves generated outside the body to break a kidney or urinary stone into smaller fragments.

The fragments can then pass through the urinary tract. ESWL may be suitable for selected stones depending on their size, location, density and the patient's anatomy.

Potential advantages include:

• No incision into the kidney

• A non-invasive approach to stone fragmentation

• Suitability for selected kidney and ureteral stones

Possible limitations include:

• More than one treatment session may be required

• Fragments may not clear completely

• Temporary blood in urine or discomfort may occur

• A fragment may obstruct the ureter

• Some stones are less suitable for ESWL because of their location or density

Your treating specialist will assess whether ESWL is likely to be effective for your particular stone.

5. Ureteroscopy and Laser Lithotripsy

Ureteroscopy involves passing a thin instrument through the urinary passage to locate a stone in the ureter or kidney. A laser can be used to fragment the stone, and small pieces may be removed with specialized instruments.

This option may be considered when:

• A ureteral stone is unlikely to pass

• A stone causes persistent symptoms

• ESWL is unsuitable or has not worked

• Direct visualization and stone removal are preferred

Some patients need a temporary ureteral stent to support urine drainage after the procedure.

Possible risks include infection, bleeding, ureteral injury, stent discomfort and residual fragments. The likelihood of complete clearance depends on the stone burden and clinical circumstances.

6. Percutaneous Nephrolithotomy (PCNL)

For larger or complex kidney stones, percutaneous nephrolithotomy (PCNL) may be recommended.

During PCNL, the surgeon creates a small access tract through the skin of the back into the kidney. Instruments are used to fragment and remove the stone.

PCNL is commonly considered for large renal stones, including stones larger than 2 cm, although the final decision depends on the patient's anatomy, stone characteristics and overall health.

PCNL may offer substantial stone clearance for selected large stones, but it requires an operation and anesthesia. Potential risks include bleeding, infection, injury to nearby structures and the need for additional treatment.

7. What If a Kidney Stone Is Blocking Urine Flow?

A stone can obstruct urine drainage from the kidney. Persistent obstruction may impair kidney function, particularly when both kidneys are affected or the person has only one functioning kidney.

Treatment may involve removing the stone or restoring drainage through a ureteral stent or nephrostomy tube, depending on the situation.

When Infection and Obstruction Occur Together

An infected, obstructed urinary tract is a medical emergency.

Warning signs can include:

• Fever or chills

• Severe flank or back pain

• Vomiting

• Markedly reduced urine output

• Feeling extremely unwell

Urgent drainage and antibiotics may be required. Definitive stone removal is generally delayed until the infection is controlled.

Do not attempt to manage these symptoms at home.

8. How Do Doctors Choose the Best Stone Treatment?

A treatment plan is based on test results and the patient's clinical condition rather than stone size alone.

A clinician may recommend:

Urine tests: To look for blood, infection and other abnormalities.

Blood tests: To assess creatinine, kidney function, electrolytes and signs of infection when appropriate.

Ultrasound or CT imaging: To identify stone size, location, number and possible obstruction.

Stone analysis: To identify the composition of a passed or removed stone.

The assessment may also consider pregnancy, age, medications, previous procedures, kidney function and other medical conditions.

9. Food and Lifestyle Changes to Prevent More Stones

Removing a stone does not eliminate the risk of forming another. Prevention is more effective when the stone type and relevant risk factors are known.

Maintain Appropriate Hydration

For many people, adequate fluid intake helps dilute urine and reduce the concentration of stone-forming substances. The recommended amount should be individualized, especially in kidney or heart disease.

Reduce Excess Salt

High sodium intake can increase urinary calcium in some people and may contribute to stone risk. Reducing excessive salt can be helpful.

Do Not Automatically Avoid Dietary Calcium

People with calcium stones should not usually eliminate normal dietary calcium without medical advice. Calcium needs should be individualized according to stone type and overall health.

Adjust Protein and Oxalate When Appropriate

Some people may benefit from changes in animal protein or high-oxalate foods, depending on their stone composition and urine test results. A renal dietitian or clinician can help tailor the diet.

Consider a Metabolic Evaluation

People with recurrent stones or other risk factors may benefit from stone analysis and, in selected cases, a 24-hour urine evaluation. Results can guide targeted prevention and medication decisions.

10. How Long Does Kidney Stone Treatment Take?

The timeline varies considerably.

• Small stones: May pass naturally, sometimes over days or weeks, with appropriate monitoring.

• Medicines: May be used for symptom relief or to support passage in selected cases.

• ESWL: May require follow-up and sometimes additional sessions to clear fragments.

• Ureteroscopy with laser: Many patients go home the same day, but recovery and stent management vary.

• PCNL: May require hospital observation and a longer recovery than less invasive procedures.

These are general patterns, not a guarantee of recovery time. The treating team should explain the expected course for your particular stone and procedure.

When Should You Seek Immediate Medical Care?

Do not wait for a routine appointment if kidney stone symptoms occur with:

• Fever or chills

• Severe or persistent pain

• Repeated vomiting or inability to keep fluids down

• Very little or no urine

• Confusion or severe weakness

• Known obstruction with worsening symptoms

Severe pain or bleeding associated with a suspected stone warrants prompt medical assessment.

Frequently Asked Questions

What are the best ways to treat kidney stones?

Treatment may involve observation, prescribed pain relief, medicines to support passage in selected cases, ESWL, ureteroscopy with laser lithotripsy or PCNL. The right option depends on stone size, location, symptoms and complications.

Can kidney stones be treated without surgery?

Some small stones can pass naturally with medical guidance and monitoring. Larger, obstructing, infected or persistently painful stones may need a procedure.

Can drinking water remove kidney stones?

Adequate hydration supports prevention and may be advised during conservative management, but excessive water does not reliably remove a large or obstructing stone. Fluid advice must account for kidney and heart conditions.

Which medicine is best for kidney stones?

There is no single best medicine for every stone. Pain medicines, selected medical expulsive therapy and stone-specific treatments are chosen according to the patient's condition and stone characteristics.

Is laser treatment better than ESWL?

Neither is best for every patient. Laser treatment through ureteroscopy and ESWL have different advantages and limitations. Stone size, location, density, anatomy and the need for complete clearance influence the choice.

When does a kidney stone require surgery?

A procedure may be needed when the stone is unlikely to pass, causes persistent pain, blocks urine flow, grows, contributes to infection or threatens kidney function.

Can kidney stones return after treatment?

Yes. Recurrence is possible. Stone analysis, appropriate fluid intake, individualized dietary changes and preventive medicines for selected patients may reduce future risk.

Conclusion

The most effective ways to treat kidney stones depend on the size and location of the stone, its likelihood of passing naturally, the condition of the urinary tract and the patient's kidney function.

Some stones can be managed with observation and prescribed medicines. Others may need ESWL, ureteroscopy with laser lithotripsy or PCNL. Home care and dietary changes can support recovery and help prevent recurrence, but they should not replace medical assessment when complications are possible.

Fever or chills with suspected obstruction, very little urine, repeated vomiting or severe pain requires prompt medical attention.
