Renal stone surgery refers to procedures used to remove or break kidney stones when they are unlikely to pass naturally, are causing significant symptoms or create a risk to kidney function.
Kidney stones vary considerably in size, location and composition. A small stone that is likely to pass may only require observation and medical management, whereas a larger or obstructing stone may require an intervention.
Modern stone treatment includes several minimally invasive options. The appropriate procedure depends on the stone's characteristics and the patient's overall health rather than using the same operation for everyone.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides specialist evaluation of kidney stones and related kidney-function problems.
When Does a Kidney Stone Need Surgery?
Not every renal stone requires an operation.
A procedure may be considered when a stone:
-
Causes repeated or severe pain
-
Blocks urine flow
-
Is associated with infection
-
Causes deterioration in kidney function
-
Is too large to pass naturally
-
Continues to grow
-
Causes repeated urinary problems
-
Remains in the urinary tract despite observation
-
Is associated with significant bleeding or other complications
-
Is unlikely to pass because of its size or location
The decision is based on imaging, symptoms, kidney function, obstruction and other clinical factors.
Can Kidney Stones Pass Without Surgery?
Yes.
Some smaller stones can pass through the urinary tract naturally.
Doctors may recommend observation when:
-
The stone is small enough to have a reasonable chance of passage
-
There is no significant obstruction
-
There is no serious infection
-
Kidney function is stable
-
Symptoms can be controlled
-
Follow-up is possible
The patient may need repeat imaging to confirm whether the stone has passed or remains in place.
Main Types of Renal Stone Surgery
Several procedures are available for kidney stone removal.
The most appropriate treatment depends on the stone's size, location, number, anatomy and other patient-specific factors.
1. Ureteroscopy With Laser Lithotripsy
Ureteroscopy is a minimally invasive procedure in which a small scope is passed through the natural urinary passage to reach the stone.
Once the stone is visualized, a laser can fragment it into smaller pieces.
The fragments may then be removed or allowed to pass naturally, depending on their size and the procedure performed.
A temporary ureteral stent may be placed in selected patients.
When Is Ureteroscopy Used?
It may be considered for stones located in:
-
The ureter
-
The kidney
-
Certain difficult-to-access areas of the urinary tract
The suitability depends on stone size, location and patient anatomy.
2. PCNL for Larger Kidney Stones
Percutaneous nephrolithotomy (PCNL) is commonly considered for larger or complex kidney stones.
A small access tract is created through the skin into the kidney. Specialized instruments are then used to break and remove the stone.
PCNL can be particularly useful for:
-
Large kidney stones
-
Multiple stones
-
Complex stone burdens
-
Staghorn calculi
-
Stones unlikely to be effectively treated with simpler approaches
The exact technique depends on the stone burden and kidney anatomy.
3. ESWL or Shock Wave Lithotripsy
Extracorporeal shock wave lithotripsy (ESWL) uses externally generated shock waves to break selected kidney or urinary stones into smaller fragments.
The fragments can then pass through the urinary tract.
ESWL may be suitable for certain stones based on:
-
Stone size
-
Stone location
-
Stone composition
-
Patient anatomy
-
Skin-to-stone distance
-
Presence or absence of obstruction
ESWL is not appropriate for every stone.
4. Flexible Ureteroscopy
Flexible ureteroscopy allows a specialist to reach stones located within different parts of the kidney.
A flexible scope can be guided through the urinary tract to the stone.
Laser technology can then be used to fragment the stone.
This approach may be useful when a stone's location makes other treatments less suitable.
What Factors Determine the Type of Kidney Stone Surgery?
Choosing renal stone surgery is not simply a matter of selecting the procedure with the shortest name or fastest recovery.
Doctors consider:
Stone Size
Larger stones are generally less likely to pass naturally and may require an active procedure.
Stone Location
A stone in the kidney may be treated differently from one lodged in the ureter.
Number of Stones
Multiple stones may require a different treatment strategy from a single small stone.
Stone Composition
Certain stones respond differently to shock waves and other treatments.
Urinary Obstruction
Significant obstruction can change the urgency and treatment approach.
Infection
A stone with an associated urinary infection may require urgent drainage before definitive stone removal.
Kidney Function
Patients with impaired kidney function require careful treatment planning.
Patient Health
Age, medical conditions, previous surgeries, medications and anesthesia-related risks can influence the procedure selected.
Kidney Stone Surgery for an Obstructed Kidney
A blocked urinary tract requires particular attention.
If a stone blocks urine flow and infection is also present, the immediate priority may be to establish drainage rather than remove the stone during the same procedure.
Depending on the situation, drainage may involve:
-
A ureteral stent
-
A nephrostomy tube
Once the infection is controlled and the patient is stable, definitive stone treatment can be planned.
A blocked infected urinary system can become a medical emergency.
What Happens Before Renal Stone Surgery?
Before a procedure, the medical team may review:
-
Symptoms
-
Stone size and location
-
Ultrasound or CT findings
-
Kidney function
-
Urine test results
-
Blood tests
-
Current medicines
-
Previous stone procedures
-
Previous anesthesia history
-
Other medical conditions
If infection is suspected, appropriate testing and treatment are particularly important before definitive stone removal.
What Happens During Kidney Stone Surgery?
The exact process depends on the procedure.
During Ureteroscopy
A scope is inserted through the urinary tract and advanced toward the stone. Laser energy may be used to fragment the stone, followed by removal of selected fragments.
During PCNL
A small access pathway is created into the kidney. Instruments are passed through this tract to fragment and remove the stone.
During ESWL
The patient is positioned so shock waves can be focused on the stone. The waves fragment the stone without making an incision into the kidney.
The treating team determines the appropriate technique based on the individual case.
Is a Stent Needed After Kidney Stone Surgery?
A temporary ureteral stent may be placed after certain procedures.
The stent can help maintain urine drainage while the ureter heals or while small stone fragments pass.
A stent may cause temporary symptoms such as:
-
Urinary urgency
-
Frequent urination
-
Bladder discomfort
-
Flank discomfort
-
Mild blood in urine
Not every patient needs a stent.
If one is placed, the patient should follow the prescribed removal or exchange schedule.
Recovery After Renal Stone Surgery
Recovery varies according to the procedure and the patient's health.
After treatment, some patients may experience:
-
Mild urinary discomfort
-
Temporary blood in urine
-
Tiredness
-
Flank discomfort
-
Increased urinary frequency
The recovery period after ESWL may differ from recovery after ureteroscopy or PCNL.
Your doctor will provide procedure-specific instructions regarding:
-
Activity
-
Fluid intake
-
Medicines
-
Diet
-
Follow-up imaging
-
Stent removal
-
Return to work
What Should You Eat After Kidney Stone Surgery?
Dietary advice depends on the type of stone and the patient's medical condition.
General preventive measures may include:
-
Appropriate fluid intake
-
Limiting excessive sodium
-
Maintaining a balanced diet
-
Avoiding extreme dietary restrictions
-
Following stone-specific nutritional advice when recommended
Patients with chronic kidney disease may have additional dietary requirements involving potassium, phosphorus, protein or fluid.
Therefore, dietary advice should be individualized.
Can Kidney Stones Come Back After Surgery?
Yes.
Removing a stone treats the existing stone but does not necessarily eliminate the reason why stones formed.
Some people have a higher risk of recurrence because of:
-
Family history
-
Low fluid intake
-
High urinary calcium
-
High urinary oxalate
-
Uric acid abnormalities
-
Certain metabolic conditions
-
Recurrent urinary infections
-
Dietary factors
Patients with recurrent stones may benefit from metabolic testing and stone analysis.
How to Prevent Another Kidney Stone
Prevention depends on the type of stone.
A doctor may recommend:
-
Drinking an appropriate amount of fluid
-
Reducing excessive salt intake
-
Following a balanced diet
-
Maintaining a healthy body weight
-
Treating metabolic abnormalities
-
Taking prescribed preventive medicines
-
Completing follow-up urine testing when indicated
-
Monitoring for recurrent stones
Avoid following generic “kidney stone diets” without understanding the type of stone involved.
Risks of Renal Stone Surgery
Kidney stone procedures are commonly performed, but every medical procedure has potential risks.
Depending on the technique, complications can include:
-
Bleeding
-
Infection
-
Pain
-
Residual stone fragments
-
Ureteral injury
-
Need for additional treatment
-
Temporary urinary symptoms
-
Stent-related discomfort
-
Anesthesia-related complications
The risks vary between procedures and individual patients.
Your treating specialist should explain the expected benefits and potential complications before treatment.
How Long Does Kidney Stone Surgery Take?
Procedure duration varies considerably.
It depends on:
-
Stone size
-
Number of stones
-
Stone location
-
Procedure selected
-
Difficulty of access
-
Whether multiple stones require treatment
Some stones can be treated relatively quickly, while complex stone disease may require a longer procedure or staged treatment.
Is Kidney Stone Surgery Painful?
Pain levels depend on the procedure and the individual.
Modern stone procedures are generally performed with appropriate anesthesia or sedation.
Temporary discomfort may occur after treatment, particularly when passing stone fragments or when a ureteral stent is present.
Severe or worsening pain after a procedure should be reported to the treating medical team.
Can All Kidney Stones Be Removed in One Procedure?
Not always.
Large, complex or multiple stones may require:
-
More than one procedure
-
Staged ureteroscopy
-
A combination of treatment methods
-
Follow-up treatment for residual fragments
The objective is safe and effective stone clearance while minimizing unnecessary risk to the patient.
Renal Stone Surgery and Kidney Function
A stone that causes prolonged obstruction can potentially affect kidney function.
This is particularly important when:
-
Both kidneys are affected
-
The patient has only one functioning kidney
-
There is severe obstruction
-
Infection is present
-
Baseline kidney function is already reduced
People with abnormal creatinine or known chronic kidney disease may require careful kidney-function monitoring before and after stone treatment.
When Should You Seek Urgent Care for a Kidney Stone?
A known or suspected kidney stone requires urgent medical assessment if you develop:
-
Fever or chills
-
Severe or worsening flank pain
-
Very little or no urine
-
Persistent vomiting
-
Severe weakness
-
Confusion
-
Fainting
-
Significant blood in urine
-
Symptoms of infection with urinary obstruction
A blocked urinary system accompanied by infection can become dangerous and should not be managed with home remedies alone.

Frequently Asked Questions
What is renal stone surgery?
Renal stone surgery includes procedures used to break or remove kidney stones when they are unlikely to pass naturally or are causing significant symptoms, obstruction or complications.
Which surgery is best for kidney stones?
There is no single best procedure for every stone. Treatment may include ESWL, ureteroscopy with laser lithotripsy or PCNL depending on stone size, location, anatomy and patient health.
Is laser treatment better than ESWL?
Neither is universally better. Laser treatment and ESWL have different indications. The most appropriate choice depends on the characteristics of the stone and the patient's condition.
Is PCNL used for large kidney stones?
Yes. PCNL is commonly considered for larger or complex kidney stones, including some staghorn and multiple-stone cases.
Will I need a stent after kidney stone surgery?
Possibly. A temporary ureteral stent is used in selected patients, depending on the procedure and condition of the urinary tract.
Can kidney stones damage the kidneys?
Stones can potentially impair kidney function when they cause significant or prolonged obstruction, especially when infection is also present.
Do kidney stones always require an operation?
No. Some smaller stones can pass naturally and may be managed with observation and medical treatment when appropriate.
How can I prevent stones after surgery?
Prevention depends on the stone type and individual risk factors. Appropriate hydration, dietary adjustments, stone analysis and metabolic evaluation may be recommended.
Conclusion
Renal stone surgery encompasses several modern treatments for kidney stones, including ESWL, ureteroscopy with laser lithotripsy and PCNL. The right procedure depends on the stone's size, location, number, degree of obstruction, kidney function and the patient's overall health.
Some stones can pass without an operation, while others require active treatment to relieve obstruction, control symptoms or protect kidney function.
If you have recurrent kidney stones, severe flank pain, urinary obstruction or abnormal kidney-function tests, specialist evaluation can help determine whether observation or a stone-removal procedure is appropriate.
