Kidney stone removal refers to medical or procedural treatment used to clear a stone from the kidney or urinary tract when it is unlikely to pass naturally or is causing symptoms or complications.
Kidney stones form when certain minerals and salts become concentrated in urine and crystallize. Small stones can sometimes pass through the urinary tract without a procedure. Larger stones, obstructing stones or stones associated with infection may require active treatment.
The appropriate removal method depends on several factors, including stone size, location, composition, symptoms, urinary obstruction, kidney function and the patient's overall health.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialized evaluation of kidney stones and related kidney problems.
When Is Kidney Stone Removal Necessary?
Not every kidney stone requires immediate removal.
A doctor may recommend active treatment when a stone:
-
Causes persistent or severe pain
-
Blocks urine flow
-
Causes repeated urinary infections
-
Is too large to pass naturally
-
Causes worsening kidney function
-
Continues to grow
-
Remains in the urinary tract without passing
-
Causes repeated bleeding or urinary symptoms
-
Is associated with complications
The decision should be based on clinical evaluation and appropriate imaging.
Can Small Kidney Stones Pass Naturally?
Yes, some smaller stones can pass without a procedure.
The likelihood of spontaneous passage depends on factors such as:
-
Stone size
-
Stone location
-
Shape of the stone
-
Anatomy of the urinary tract
-
Previous stone history
-
Presence or absence of obstruction
A doctor may recommend observation, pain management and selected medicines when spontaneous passage is reasonably likely.
How Is the Best Kidney Stone Removal Method Chosen?
There is no single procedure that is best for every kidney stone.
Doctors consider:
Stone Size
Larger stones may be less likely to pass naturally and may require a procedure.
Stone Location
A stone in the kidney may be managed differently from one lodged in the ureter.
Stone Density
Some stones are harder and may respond differently to shock waves or laser treatment.
Symptoms
Persistent pain, recurrent bleeding or urinary symptoms may influence the treatment decision.
Infection
An infected obstructed urinary system requires urgent medical attention and may require drainage before definitive stone removal.
Kidney Function
Existing kidney disease can affect treatment planning.
Main Kidney Stone Removal Options
Common approaches include:
-
Observation and medical management
-
Extracorporeal shock wave lithotripsy (ESWL)
-
Ureteroscopy
-
Laser lithotripsy
-
Percutaneous nephrolithotomy (PCNL)
-
Other specialized procedures in selected cases
1. Medical Management and Natural Stone Passage
For appropriately selected small stones, a doctor may recommend waiting for the stone to pass naturally.
Treatment may include:
-
Pain-control medicines
-
Medicines that may facilitate stone passage in selected patients
-
Appropriate fluid advice
-
Follow-up imaging
-
Monitoring for complications
Not every patient should simply drink excessive amounts of water to force a stone out. Fluid recommendations should take the individual's medical condition into account.
2. ESWL for Kidney Stone Removal
Extracorporeal shock wave lithotripsy (ESWL) uses focused shock waves generated outside the body to break a stone into smaller fragments.
The fragments can then pass through the urinary tract.
ESWL may be considered for selected stones depending on:
-
Size
-
Location
-
Density
-
Kidney anatomy
-
Patient factors
Some stones may require more than one treatment session.
3. Ureteroscopy for Stone Removal
Ureteroscopy is a minimally invasive procedure in which a small endoscope is passed through the urinary tract to reach the stone.
The stone can then be removed or fragmented.
Ureteroscopy may be particularly useful for certain ureteral stones and kidney stones that are not suitable for or have not responded adequately to other treatments.
4. Laser Lithotripsy
During laser lithotripsy, a laser is used through an endoscopic instrument to fragment the stone.
The fragments may be removed using specialized instruments or allowed to pass naturally when appropriate.
Laser treatment is widely used for selected urinary stones and can be combined with ureteroscopy.
5. Percutaneous Nephrolithotomy
Percutaneous nephrolithotomy (PCNL) is a procedure generally used for larger or complex kidney stones.
A small access tract is created through the skin into the kidney, allowing instruments to reach and remove or fragment the stone.
PCNL may be preferred for certain large stone burdens where other approaches are less suitable.
Kidney Stone Removal According to Stone Size
Stone size is an important consideration, but it is not the only factor.
Small Stones
Small stones may pass naturally, particularly when located in a favorable position.
Medium-Sized Stones
Some may require ESWL, ureteroscopy or another procedure depending on location and symptoms.
Large Stones
Larger stones are less likely to pass naturally and may require procedural treatment.
Complex or Staghorn Stones
Large branching stones occupying multiple areas of the kidney often require specialized treatment planning, frequently involving percutaneous procedures.
Kidney Stone Removal From the Ureter
A ureteral stone can cause severe pain because the ureter is a narrow tube carrying urine from the kidney to the bladder.
Treatment depends on:
-
Stone size
-
Stone location
-
Degree of obstruction
-
Pain severity
-
Infection status
-
Kidney function
Some ureteral stones can pass naturally, while others require medication or a procedure such as ureteroscopy.
Kidney Stone Removal and Urinary Infection
A kidney stone combined with urinary obstruction and infection can be a medical emergency.
Symptoms that require prompt assessment include:
-
Fever
-
Chills
-
Severe flank pain
-
Vomiting
-
Weakness
-
Difficulty passing urine
-
Reduced urine output
In an infected obstructed system, immediate drainage may be necessary before definitive stone removal.
Tests Before Kidney Stone Removal
The medical team may recommend several investigations.
Urine Testing
Urine tests can look for:
-
Blood
-
Infection
-
Crystals
-
Other abnormalities
Blood Tests
Depending on the situation, tests may assess:
-
Creatinine
-
Kidney function
-
Electrolytes
-
Blood count
-
Other relevant parameters
Imaging
Imaging helps determine:
-
Stone size
-
Number of stones
-
Location
-
Urinary obstruction
-
Kidney anatomy
Ultrasound, X-ray or CT may be used depending on the clinical situation.
Is Kidney Stone Removal Painful?
The experience depends on the treatment used.
ESWL may cause temporary discomfort during or after treatment.
Ureteroscopy and laser lithotripsy are performed using appropriate anesthesia or sedation according to the procedure.
After treatment, patients may experience temporary:
-
Flank discomfort
-
Burning during urination
-
Blood in urine
-
Urinary frequency
-
Passage of stone fragments
The treating team provides appropriate pain-management instructions.
Kidney Stone Removal Recovery
Recovery depends on the procedure.
After a less invasive procedure, some patients return to normal activities relatively quickly.
Others may require more recovery time, particularly after treatment of larger or more complicated stones.
Follow-up may include:
-
Imaging
-
Urine testing
-
Kidney-function testing
-
Monitoring for residual fragments
-
Stent removal when a stent has been placed
Patients should follow the specific recovery instructions given by their healthcare team.
What Is a Ureteral Stent?
A ureteral stent is a thin tube placed inside the ureter to help maintain urine flow from the kidney to the bladder.
A stent may be used after certain stone procedures or when temporary drainage is needed.
Some patients experience:
-
Urinary frequency
-
Urgency
-
Flank discomfort
-
Bladder discomfort
Stents are generally intended for a specific period and should be removed or changed according to the treating doctor's instructions.
Can Kidney Stones Come Back After Removal?
Yes.
Removing a stone does not necessarily eliminate the reason it formed.
Some people are prone to recurrent stones because of:
-
Low fluid intake
-
High sodium intake
-
Certain dietary patterns
-
Metabolic abnormalities
-
Family history
-
Certain medical conditions
-
Specific medications
A recurrent stone former may benefit from a metabolic evaluation and preventive strategy.
How to Reduce the Risk of Future Kidney Stones
Prevention should be individualized according to the stone type and the patient's health.
General measures may include:
-
Maintaining appropriate hydration
-
Limiting excessive dietary salt
-
Following a balanced diet
-
Maintaining a healthy body weight
-
Avoiding unnecessary dietary restrictions
-
Taking prescribed preventive medicines when indicated
-
Investigating recurrent stone formation
People with kidney, heart or other medical conditions may have specific fluid restrictions, so they should follow their doctor's advice.
Should You Save a Passed Kidney Stone?
If a stone is naturally passed, your doctor may recommend collecting it for analysis.
Knowing the stone's composition can help identify why it formed and guide future prevention.
Common stone types include:
-
Calcium oxalate
-
Calcium phosphate
-
Uric acid
-
Struvite
-
Cystine
Treatment and prevention differ according to stone composition.
Kidney Stone Removal and Kidney Function
Most appropriately managed kidney stones do not result in permanent kidney failure.
However, repeated obstruction, severe infection or prolonged untreated urinary blockage can damage kidney function.
People with existing kidney disease require particularly careful assessment when a stone is causing obstruction or infection.
When Is Kidney Stone Removal an Emergency?
Seek urgent medical assessment if a suspected kidney stone is accompanied by:
-
Fever or chills
-
Severe or worsening pain
-
Persistent vomiting
-
Difficulty passing urine
-
Very low urine output
-
Significant weakness
-
Known urinary obstruction
-
A single functioning kidney with obstructive symptoms
An infected obstructed kidney can deteriorate rapidly and may require urgent drainage.

Frequently Asked Questions About Kidney Stone Removal
What is the fastest way to remove a kidney stone?
There is no single fastest method for every stone. Treatment depends on the stone's size, location, obstruction, symptoms and other patient factors. Procedures such as ureteroscopy, laser lithotripsy or ESWL may be appropriate in selected cases.
Can a 5 mm kidney stone pass naturally?
Some stones around this size can pass naturally, but the likelihood varies with location and individual anatomy. Medical assessment helps determine whether observation or active treatment is more appropriate.
Is laser treatment better than ESWL?
Both have advantages and limitations. The best option depends on stone size, location, density and patient-specific factors.
How long does kidney stone removal take?
Treatment duration varies significantly depending on the procedure and complexity of the stone.
Do kidney stones always need surgery?
No. Some small stones can pass naturally with appropriate medical management and monitoring.
Can kidney stones damage the kidneys?
A stone can potentially affect kidney function when it causes prolonged obstruction, repeated infection or other complications.
Can kidney stones be removed without surgery?
Selected stones can be managed without surgery, including observation and medical treatment. ESWL is also a non-invasive stone-fragmentation option for appropriately selected stones.
Conclusion
Kidney stone removal is not a one-size-fits-all treatment. Some stones can pass naturally, while others require active intervention because of their size, location, persistent symptoms, obstruction, infection or effect on kidney function.
Treatment options may include medical management, ESWL, ureteroscopy, laser lithotripsy and PCNL. Choosing the right approach requires assessment of the stone and the patient's overall health.
Early evaluation can also help identify factors contributing to recurrent stones and allow preventive measures to be introduced.
