Kidney stones do not always require surgery. Some small stones can pass naturally, particularly when they are not causing significant obstruction or other complications.
However, surgical removal of kidney stones may be recommended when a stone is too large to pass, causes persistent obstruction, produces recurrent severe pain, contributes to infection or threatens kidney function.
The choice of procedure depends on several factors, including:
-
Stone size
-
Stone location
-
Number of stones
-
Kidney anatomy
-
Degree of obstruction
-
Presence of infection
-
Kidney function
-
Previous stone treatments
-
Overall health
There is no single procedure that is best for every patient.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist assessment of kidney stones and kidney-function concerns and can help determine when procedural treatment may be required.
Why Do Some Kidney Stones Need to Be Removed?
A stone may need intervention when it creates a problem that is unlikely to resolve safely with observation.
Common reasons include:
Persistent Urinary Obstruction
A stone lodged in the ureter can interfere with urine drainage from the kidney to the bladder.
Prolonged obstruction may damage kidney function.
Recurrent or Severe Pain
Repeated renal colic that cannot be adequately controlled may be an indication for active stone treatment.
Urinary Infection
A stone associated with recurrent infection may need definitive treatment after any urgent infection and obstruction have been appropriately managed.
Large Stone Burden
Larger kidney stones are less likely to pass naturally and may require a procedure.
Kidney Function Concerns
Obstruction affecting kidney function requires careful assessment and timely treatment.
Stone Growth
An enlarging stone may eventually become more difficult to treat or cause obstruction.
What Are the Main Surgical Options for Kidney Stones?
Modern kidney stone treatment includes several minimally invasive procedures.
The most appropriate option is selected according to the stone's characteristics.
1. Ureteroscopy and Laser Lithotripsy
Ureteroscopy is performed through the natural urinary passage.
A small camera is guided through the urethra and bladder into the ureter or kidney.
Once the stone is located, laser energy can fragment it into smaller pieces.
Depending on the situation, fragments may be removed with specialized instruments or allowed to pass naturally.
Ureteroscopy May Be Considered For:
-
Ureteric stones
-
Selected kidney stones
-
Stones causing obstruction
-
Stones that have not passed naturally
-
Patients for whom other approaches are unsuitable
A temporary ureteric stent may be placed in selected cases.
2. Percutaneous Nephrolithotomy (PCNL)
PCNL is commonly used for larger or complex kidney stones.
A small tract is created through the skin into the kidney. A specialized instrument is then introduced directly into the kidney to break and remove the stone.
PCNL may be considered for:
-
Large kidney stones
-
Staghorn stones
-
Multiple or complex stones
-
Significant stone burden
-
Stones that are unlikely to be cleared effectively by simpler techniques
Compared with traditional open stone surgery, PCNL uses a much smaller access tract.
3. Shock-Wave Lithotripsy
Shock-wave lithotripsy, or SWL, uses externally generated shock waves to break selected stones into smaller fragments.
The fragments can then pass through the urinary tract.
SWL may be suitable for certain kidney or ureteric stones, depending on:
-
Stone size
-
Stone location
-
Stone composition
-
Body habitus
-
Urinary anatomy
Not every stone is suitable for shock-wave treatment.
4. Laparoscopic or Robotic Stone Surgery
Laparoscopic or robotic surgery has a more selective role in modern stone management.
It may be considered in unusual or complex situations, particularly when a stone is associated with an anatomical abnormality that also requires surgical correction.
For many patients, ureteroscopy or PCNL is preferred instead.
Is Kidney Stone Surgery Always Better Than Waiting?
No.
Observation can be appropriate for selected patients.
A small, uncomplicated stone may pass naturally without surgery.
However, prolonged observation may not be appropriate if there is:
-
Persistent obstruction
-
Infection
-
Worsening kidney function
-
Uncontrolled pain
-
Significant hydronephrosis
-
Stone growth
-
A solitary functioning kidney
A doctor can determine whether observation is safe based on imaging and clinical findings.
How Is the Right Kidney Stone Surgery Selected?
Before recommending a procedure, the healthcare team may review:
Stone Size
A small stone and a large stone may require completely different treatment strategies.
Stone Location
A stone in the kidney may be managed differently from one lodged in the ureter.
Stone Composition
Certain stone types respond differently to shock-wave treatment and other procedures.
Kidney Anatomy
Anatomical variations can influence which procedure provides the best access.
Urinary Obstruction
The degree and duration of obstruction can affect treatment urgency.
Infection
An infected obstructed urinary system requires urgent medical attention and appropriate drainage before definitive stone treatment in many cases.
Kidney Function
Creatinine and eGFR help doctors understand whether the kidneys are being affected.
What Tests Are Done Before Kidney Stone Removal?
Evaluation may include several investigations.
Ultrasound
Ultrasound can identify many stones and may show:
-
Hydronephrosis
-
Kidney swelling
-
Urinary obstruction
-
Other structural abnormalities
CT Scan
CT imaging can provide detailed information about:
-
Exact stone location
-
Stone size
-
Number of stones
-
Stone burden
-
Urinary anatomy
-
Degree of obstruction
Blood Tests
Doctors may check:
-
Serum creatinine
-
eGFR
-
Electrolytes
-
Complete blood count
-
Blood glucose
-
Other tests based on the planned procedure
Urine Tests
Urinalysis and urine culture may be performed to identify blood or infection.
Why Is a Urinary Infection Important Before Surgery?
A kidney stone can block urine flow while bacteria are present in the urinary tract.
This combination can be dangerous.
If infection and significant obstruction occur together, urgent drainage of the urinary system may be required.
Definitive stone removal may be performed after the infection has been appropriately treated and the patient is medically stable.
Seek urgent medical care if you have:
-
Fever with kidney stone symptoms
-
Chills
-
Severe flank pain
-
Vomiting
-
Weakness
-
Confusion
-
Reduced urine output
What Happens During Kidney Stone Surgery?
The exact process depends on the procedure.
For ureteroscopy:
-
Anesthesia is administered.
-
A small scope is introduced through the urinary tract.
-
The stone is located.
-
Laser energy may fragment the stone.
-
Fragments may be removed.
-
A temporary stent may be placed when appropriate.
For PCNL:
-
Anesthesia is administered.
-
A small access tract is created into the kidney.
-
A nephroscope is introduced.
-
The stone is fragmented.
-
Stone fragments are removed.
-
A temporary drainage tube or stent may be used depending on the situation.
What Is a Ureteric Stent?
A ureteric stent is a thin flexible tube placed inside the ureter to help urine drain from the kidney to the bladder.
A stent may be used after some stone procedures to:
-
Maintain urine drainage
-
Reduce the risk of obstruction from swelling
-
Support healing
-
Help manage certain urinary-tract conditions
Some patients experience temporary symptoms such as urinary urgency, frequency or discomfort while a stent is in place.
The stent should be removed or exchanged according to the treating doctor's instructions.
How Long Does Kidney Stone Surgery Take?
The duration depends on:
-
Stone size
-
Number of stones
-
Stone location
-
Procedure selected
-
Anatomical complexity
-
Whether more than one treatment session is needed
Some stones can be treated in a single procedure, while complex stone disease may require staged treatment.
The surgeon should provide an individualized estimate.
What Is Recovery Like After Kidney Stone Surgery?
Recovery varies depending on the procedure and the patient's health.
After treatment, patients may experience:
-
Mild urinary discomfort
-
Blood in the urine for a short period
-
Urinary frequency
-
Temporary flank discomfort
-
Fatigue
These symptoms should be discussed with the medical team if they are severe, persistent or worsening.
Follow-up imaging may be recommended to determine whether any residual stone fragments remain.
Can Kidney Stones Return After Surgery?
Yes.
Surgical removal eliminates existing stones but does not necessarily eliminate the reason they formed.
Stone recurrence may be associated with:
-
Low fluid intake
-
High sodium intake
-
Dietary factors
-
Metabolic abnormalities
-
Family history
-
Certain medical conditions
-
Previous recurrent stones
Patients with repeated stones may benefit from a metabolic evaluation.
How Can Future Stones Be Prevented?
Prevention depends on the stone type and individual risk factors.
Maintain Appropriate Hydration
Adequate fluid intake can help reduce the concentration of stone-forming substances in urine.
However, people with advanced kidney disease or certain heart conditions may have individualized fluid limits.
Reduce Excess Salt
High sodium intake can increase urinary calcium in some people.
Follow Stone-Specific Dietary Advice
Depending on the stone composition, recommendations may involve:
-
Sodium
-
Calcium
-
Oxalate
-
Animal protein
-
Purine-rich foods
Avoid extreme dietary restrictions without professional advice.
Analyze Recurrent Stones
Stone analysis and metabolic testing can sometimes identify preventable risk factors.
Can Kidney Stone Surgery Damage the Kidney?
Modern stone procedures are designed to remove stones while preserving kidney tissue.
As with any medical procedure, complications can occur.
Potential risks depend on the technique and may include:
-
Bleeding
-
Infection
-
Injury to the urinary tract
-
Residual stone fragments
-
Scar formation
-
Need for repeat procedures
-
Anesthesia-related complications
The potential benefits and risks should be discussed before treatment.
What If the Stone Is Very Large?
Very large stones often require an active treatment strategy.
PCNL is commonly considered for significant renal stone burdens.
In particularly complex cases, more than one procedure may be necessary.
A large staghorn stone, for example, may require staged treatment rather than attempting complete removal in a single session.
Does Kidney Stone Surgery Improve Kidney Function?
If a stone is obstructing urine flow, relieving the obstruction may help preserve or improve kidney function in appropriate cases.
However, recovery depends on:
-
Duration of obstruction
-
Severity of obstruction
-
Existing kidney disease
-
Presence of infection
-
Whether one or both kidneys are affected
Permanent damage may occur if severe obstruction is prolonged.
When Should a Kidney Stone Be Treated Urgently?
Urgent medical assessment is particularly important when a suspected stone is associated with:
-
Fever or chills
-
Severe uncontrolled pain
-
Persistent vomiting
-
Very little or no urine
-
Significant urinary obstruction
-
Worsening kidney function
-
A solitary functioning kidney
-
Rapid deterioration
An infected obstructed urinary system can become a medical emergency.

Frequently Asked Questions
What is the best surgery for kidney stone removal?
There is no single best procedure for every patient. Ureteroscopy, laser lithotripsy, PCNL, shock-wave lithotripsy and selected surgical approaches may be considered depending on stone characteristics.
Can a kidney stone be removed without surgery?
Yes. Some smaller stones can pass naturally. Medication and observation may be appropriate in selected uncomplicated cases.
Is PCNL used for large kidney stones?
Yes. PCNL is commonly used for larger or complex kidney stones because it provides direct access to the kidney.
Is laser treatment a surgical procedure?
Ureteroscopic laser lithotripsy is a minimally invasive procedure in which a laser fragments the stone inside the urinary tract.
How long does kidney stone surgery recovery take?
Recovery varies according to the procedure, stone complexity and overall health. The treating team can provide specific postoperative guidance.
Can kidney stones come back after surgical removal?
Yes. Removing a stone does not necessarily eliminate the underlying tendency to form stones. Preventive evaluation may reduce recurrence risk.
Is kidney stone surgery urgent when there is fever?
A fever with a suspected obstructing kidney stone can indicate an infected obstruction and requires urgent medical assessment.
Conclusion
Surgical removal of kidney stones is recommended when a stone is unlikely to pass safely or is causing complications such as persistent obstruction, recurrent severe pain, infection or kidney-function problems.
Modern treatment offers several minimally invasive options, including ureteroscopy with laser lithotripsy, PCNL and shock-wave lithotripsy. Laparoscopic or robotic surgery may have a role in selected complex cases.
