Not every kidney stone requires surgery.
Small stones may sometimes pass naturally, while some asymptomatic stones can be monitored under medical supervision. However, a procedure may become necessary when a stone is too large to pass, causes persistent obstruction, produces recurrent severe pain, leads to infection, affects kidney function or is unlikely to clear on its own.
The term kidney stone treatment surgery can refer to several different procedures. The appropriate option depends on:
-
Stone size
-
Stone location
-
Number of stones
-
Stone density and composition
-
Urinary obstruction
-
Infection
-
Kidney anatomy
-
Kidney function
-
Previous stone treatments
-
Overall health
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides kidney-related evaluation and can coordinate appropriate specialist care for patients with kidney stones and associated kidney-function problems.
Does Every Kidney Stone Need an Operation?
No.
Treatment is selected according to the characteristics of the stone and the patient's clinical condition.
A smaller stone with no infection or significant obstruction may be managed with observation and appropriate medical treatment.
A larger stone, however, may have a low chance of spontaneous passage and may require active removal.
Factors that can favor intervention include:
-
Persistent or recurrent severe pain
-
Urinary obstruction
-
Recurrent urinary infection
-
Declining kidney function
-
Increasing stone size
-
A stone unlikely to pass naturally
-
Occupational or lifestyle circumstances requiring definitive clearance
-
Failure of previous conservative treatment
The decision should be made after appropriate imaging and clinical assessment.
How Do Doctors Decide Which Stone Surgery Is Appropriate?
There is no single procedure that is suitable for every kidney stone.
The treatment plan is influenced by the stone's:
Size + location + density + anatomy + obstruction status + infection status
For example, a small ureteric stone may be suitable for ureteroscopy, while a large complex renal stone may require PCNL.
A doctor may review ultrasound or CT imaging before recommending the procedure.
Main Types of Kidney Stone Treatment Surgery
Several techniques are used to remove or fragment urinary stones.
1. Ureteroscopy With Laser Lithotripsy
Ureteroscopy (URS) is a commonly used minimally invasive procedure for stones located in the ureter or kidney.
A thin endoscope is introduced through the natural urinary passage and guided toward the stone.
Once the stone is reached, a laser may be used to fragment it.
The smaller pieces can then be removed with specialized instruments or allowed to pass naturally when appropriate.
Why Is Laser Treatment Used?
Laser lithotripsy can fragment stones into smaller pieces and may allow the surgeon to treat stones in different locations within the urinary tract.
Flexible ureteroscopy can also be used for selected kidney stones and is often referred to as RIRS (retrograde intrarenal surgery) when the kidney's collecting system is accessed using a flexible scope.
2. RIRS for Kidney Stones
RIRS is a minimally invasive endoscopic technique used to reach stones inside the kidney.
A flexible ureteroscope is passed through the urinary tract into the kidney.
The stone can then be fragmented, often using laser energy.
RIRS may be considered for selected renal stones based on:
-
Stone size
-
Stone location
-
Stone density
-
Kidney anatomy
-
Patient factors
Larger stone burdens may sometimes require more than one session.
3. PCNL for Large Kidney Stones
Percutaneous nephrolithotomy (PCNL) is commonly used for larger or complex kidney stones.
A small access tract is created through the skin into the kidney. Instruments are then introduced through this tract to fragment and remove the stone.
PCNL may be considered for:
-
Large renal stones
-
Complex stone burdens
-
Staghorn stones
-
Stones that are unlikely to clear effectively with less invasive approaches
The exact technique depends on stone characteristics and patient anatomy.
4. ESWL or Shock Wave Lithotripsy
Extracorporeal shock wave lithotripsy (ESWL/SWL) uses externally generated shock waves to break a stone into smaller fragments.
It does not require an incision.
However, its effectiveness depends on factors such as:
-
Stone size
-
Stone location
-
Stone density
-
Body habitus
-
Kidney anatomy
Some stones may require more than one session, and fragments may need to pass through the urinary tract afterward.
ESWL is therefore not automatically the best option for every stone.
What Is the Difference Between Laser Surgery and PCNL?
Both can be used to treat kidney stones, but the approach is different.
| Feature | Laser Ureteroscopy / RIRS | PCNL |
|---|---|---|
| Access | Through natural urinary passage | Through a small tract into the kidney |
| Common use | Selected ureteric and renal stones | Larger or complex renal stones |
| Stone fragmentation | Usually laser | Mechanical/energy fragmentation through the access tract |
| Incision | No skin incision | Small skin incision |
| Staging | May be required for larger stone burdens | May also be staged for complex cases |
| Suitability | Depends on stone and anatomy | Depends on stone burden and kidney anatomy |
The final choice should be based on individual imaging and clinical findings.
Can Kidney Stone Surgery Be Done Without a Large Incision?
Many modern stone procedures are minimally invasive.
Ureteroscopy and RIRS are performed through the natural urinary passage.
PCNL uses a small access tract rather than the large surgical incision associated with traditional open surgery.
The appropriate approach depends on the stone.
Open surgery is now uncommon for routine kidney stones because minimally invasive techniques can treat many cases.
What Happens Before Kidney Stone Surgery?
Before a procedure, the doctor may evaluate:
Imaging
Ultrasound or CT may be reviewed to determine:
-
Stone size
-
Exact location
-
Number of stones
-
Stone density
-
Urinary obstruction
-
Kidney anatomy
Urine Testing
Urinalysis and urine culture may be recommended to identify infection.
Blood Tests
Depending on the situation, tests may include:
-
Serum creatinine
-
eGFR
-
Electrolytes
-
Hemoglobin
-
Other preoperative investigations
Medication Review
Blood thinners and other medicines may require specific instructions before a procedure.
Patients should never stop prescribed medication without guidance from their treating doctor.
Why Must Infection Be Checked Before Stone Surgery?
A urinary infection can significantly affect the timing and safety of stone treatment.
If there is an obstructed urinary system with infection, urgent drainage may be necessary rather than immediately performing definitive stone removal.
Drainage may involve:
-
Ureteral stenting
-
Nephrostomy
After the infection has been appropriately treated, definitive stone removal can be planned.
Fever and urinary obstruction together require urgent medical evaluation.
Is a Stent Used During Kidney Stone Surgery?
A ureteral stent may be placed before or after certain stone procedures.
A stent helps maintain urine flow between the kidney and bladder.
It may be used when:
-
The ureter is swollen
-
Stone fragments need to pass
-
There is a risk of temporary obstruction
-
The procedure has irritated the ureter
-
Drainage needs to be maintained
A stent can cause temporary:
-
Urinary urgency
-
Frequent urination
-
Burning
-
Flank discomfort
-
Blood in urine
Stents are generally temporary and should be removed or exchanged according to the treating specialist's plan.
How Long Does Kidney Stone Surgery Take?
The duration varies substantially.
It depends on:
-
Stone size
-
Number of stones
-
Location
-
Procedure selected
-
Stone density
-
Patient anatomy
-
Whether the treatment is staged
A simple procedure may be relatively short, while complex or multiple stones can require longer treatment or more than one session.
The treating surgical team can provide an individualized estimate.
Is Kidney Stone Surgery Painful?
Modern stone procedures are generally performed with anesthesia or appropriate sedation, so significant pain during the procedure is controlled.
After surgery, some patients may experience:
-
Mild flank discomfort
-
Burning while urinating
-
Urinary urgency
-
Blood in urine
-
Discomfort from a ureteral stent
-
Passage of small stone fragments
Pain severity varies according to the procedure and individual circumstances.
What Is Recovery Like After Kidney Stone Surgery?
Recovery depends on the procedure and the amount of stone treated.
After a minimally invasive procedure, patients may be advised to:
-
Take prescribed medicines
-
Follow individualized fluid instructions
-
Avoid strenuous activity for the recommended period
-
Watch for fever or worsening pain
-
Attend scheduled follow-up
-
Return for stent removal when required
Passing small fragments after stone fragmentation can sometimes cause temporary discomfort.
Can Kidney Stones Come Back After Surgery?
Yes.
Stone removal treats the existing stone but does not necessarily eliminate the metabolic or dietary factors that caused stone formation.
Recurrence can be associated with:
-
Low fluid intake
-
High dietary sodium
-
Certain metabolic abnormalities
-
Family history
-
Recurrent urinary infection
-
Specific dietary patterns
-
Certain medical conditions
For recurrent stone formers, the treating doctor may recommend:
-
Stone analysis
-
Blood testing
-
Urine testing
-
Metabolic evaluation
-
Dietary changes
-
Preventive medication in selected cases
How Can You Prevent Another Kidney Stone?
Prevention should be tailored to the type of stone and individual risk factors.
General measures may include:
Maintain Appropriate Fluid Intake
Adequate fluid intake can help reduce the concentration of stone-forming substances in urine.
However, fluid goals should be individualized in people with kidney, heart or other medical conditions.
Reduce Excess Salt
High sodium intake can increase urinary calcium excretion in susceptible people.
Follow an Individualized Diet
Dietary advice depends on the stone type.
People with calcium stones should not automatically eliminate normal dietary calcium without professional advice.
Complete Stone Analysis
If a stone or fragment is recovered, laboratory analysis can help determine its composition.
Consider Metabolic Evaluation
People with recurrent, multiple or high-risk stones may benefit from a more detailed evaluation to identify factors contributing to recurrence.
What Are the Risks of Kidney Stone Surgery?
As with any medical procedure, complications are possible.
Depending on the procedure, potential risks may include:
-
Bleeding
-
Infection
-
Temporary urinary discomfort
-
Residual stone fragments
-
Ureteral injury
-
Need for a stent
-
Urinary obstruction
-
Need for another procedure
-
Anesthesia-related complications
The risks differ between URS, RIRS, PCNL and ESWL.
Your treating specialist should explain the expected benefits and possible risks before the procedure.
When Should You Seek Urgent Help After Stone Surgery?
Contact a healthcare professional urgently or seek emergency care if you develop:
-
High fever or chills
-
Severe or worsening pain
-
Very little or no urine
-
Persistent vomiting
-
Severe weakness
-
Confusion
-
Heavy or worsening bleeding
-
Rapid deterioration
These symptoms can indicate infection, obstruction or another complication.
Can Kidney Stone Surgery Damage the Kidney?
Modern stone procedures are designed to remove stones while minimizing injury to the urinary tract.
However, every procedure has potential risks.
The impact on the kidney depends on factors such as:
-
Existing kidney function
-
Stone burden
-
Infection
-
Duration of obstruction
-
Procedure type
-
Patient anatomy
-
Number of procedures required
Leaving a significant obstructing stone untreated can itself cause kidney damage.
Therefore, the risks of treatment and the risks of untreated stone disease should both be considered.
What Happens If the Stone Is Very Large?
Large stones may require a more comprehensive treatment plan.
Depending on the location and complexity, the doctor may consider:
-
PCNL
-
RIRS
-
Flexible ureteroscopy
-
Staged procedures
-
Combined approaches
For very large or complex stone burdens, achieving complete clearance may require more than one procedure.
Imaging plays an important role in deciding the safest approach.
Kidney Stone Surgery for Patients With Reduced Kidney Function
Patients with pre-existing kidney disease require careful assessment before stone treatment.
The medical team may review:
-
Creatinine
-
eGFR
-
Electrolytes
-
Urine output
-
Medications
-
Blood pressure
-
Infection status
The objective is to relieve obstruction or remove the stone while protecting overall kidney function.
Nephrology and urology teams may coordinate care when kidney-function problems coexist with a surgical stone condition.

Frequently Asked Questions
What is the best surgery for kidney stones?
There is no single procedure that is appropriate for every stone. Ureteroscopy with laser, RIRS, PCNL and ESWL may be considered according to stone size, location, density, anatomy and other clinical factors.
Is laser treatment better than traditional kidney stone surgery?
Laser lithotripsy is a minimally invasive technique used during ureteroscopy or RIRS. Whether it is appropriate depends on the individual stone and patient rather than being universally better.
How large does a kidney stone need to be before surgery?
There is no single size threshold that applies to every patient. Location, obstruction, symptoms, infection, kidney function and likelihood of spontaneous passage all influence the decision.
How long does kidney stone surgery recovery take?
Recovery varies according to the procedure, stone burden and individual health. Some minimally invasive procedures allow relatively quick recovery, while complex or staged treatment may require more time.
Will I need a stent after kidney stone surgery?
Some patients require a ureteral stent, while others may not. The decision depends on the procedure, ureteral condition, stone fragments and risk of obstruction.
Can a kidney stone be removed without surgery?
Some smaller stones may pass naturally with appropriate medical management. Larger or problematic stones may require active removal through procedures such as ureteroscopy, RIRS, PCNL or ESWL.
Can kidney stones return after surgery?
Yes. Removing a stone does not eliminate the factors that caused it. Stone analysis and preventive evaluation can help reduce recurrence risk in appropriate patients.
Conclusion
Kidney stone treatment surgery encompasses several minimally invasive and endoscopic techniques rather than one single operation.
Depending on the stone's size, location, density, anatomy and clinical effects, treatment may involve ureteroscopy with laser lithotripsy, RIRS, PCNL or ESWL. Some patients may require staged or combined treatment.
Before stone removal, evaluation for infection, obstruction and kidney-function impairment is important. After treatment, follow-up can help confirm stone clearance and address factors that may contribute to recurrence.
If you have persistent stone-related pain, urinary obstruction, recurrent infection, a large stone or reduced kidney function, specialist evaluation can help determine the appropriate treatment pathway.
