Introduction
Kidney and ureteral stones can cause severe pain, blood in the urine, nausea, vomiting, urinary discomfort, and sometimes urinary obstruction. When a stone is too large or unlikely to pass naturally, a procedure may be recommended to remove or fragment it.
Laser for stone removal, commonly performed during ureteroscopy with laser lithotripsy, is a minimally invasive treatment used for selected kidney and ureteral stones. During the procedure, a urologist uses a thin endoscope to reach the stone and a laser to break it into smaller fragments that can be removed or passed through the urine.
The choice of treatment depends on factors such as stone size, location, composition, urinary obstruction, infection, kidney function, and the patient's overall health.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, a super specialist nephrologist, provides comprehensive kidney stone evaluation, kidney function assessment, metabolic evaluation, prevention guidance, and coordination with experienced urology specialists when a stone-removal procedure is required.
What Is Laser for Stone Removal?
Laser stone removal is a procedure in which laser energy is used to fragment a kidney or ureteral stone.
The treatment is generally performed through the natural urinary passage rather than through a large surgical incision.
A commonly used approach is:
Ureteroscopy → Stone visualization → Laser fragmentation → Stone removal or fragment passage
The procedure is performed by a urologist, while a nephrologist can help evaluate kidney function, associated medical conditions, recurrent stone risk, and long-term prevention.
How Does Laser Kidney Stone Removal Work?
Laser stone treatment is generally performed under anesthesia.
Step 1: Pre-Procedure Evaluation
The patient may undergo:
-
Medical history and physical examination
-
Urine testing
-
Blood tests
-
Kidney function testing
-
Ultrasound or CT imaging when appropriate
The doctor evaluates the stone's size and location and checks for infection or obstruction.
Step 2: Ureteroscopy
A thin ureteroscope is carefully passed through the urinary tract to reach the ureter or kidney.
No large external incision is generally required.
Step 3: Stone Identification
The urologist visualizes the stone using the ureteroscope.
Step 4: Laser Fragmentation
Laser energy is directed at the stone to break it into smaller pieces or dust-like fragments, depending on the treatment strategy.
Step 5: Fragment Removal
Fragments may be removed using specialized instruments or left small enough to pass naturally through the urine when appropriate.
Step 6: Ureteral Stent
A temporary ureteral stent may be placed after the procedure in selected patients to help urine drain while the ureter heals.
When Is Laser Stone Removal Recommended?
Laser lithotripsy may be considered when:
-
The stone is unlikely to pass naturally
-
The stone is causing persistent symptoms
-
The stone is obstructing urine flow
-
The stone is associated with recurrent problems
-
Other treatment options are less suitable
-
The stone is located in an area that can be effectively reached using ureteroscopy
-
Active stone treatment is clinically necessary
Not every kidney stone requires laser treatment.
Small stones without significant obstruction or infection may sometimes be monitored or managed medically.
Laser Treatment for Kidney Stones vs Ureter Stones
Laser lithotripsy can be used for selected stones in both the kidney and ureter.
Ureter Stones
A ureteroscope can often reach stones located in the ureter. The stone may be fragmented with a laser and the fragments removed.
Kidney Stones
For selected kidney stones, flexible ureteroscopy may allow the urologist to access the kidney and use laser energy to fragment the stone.
The appropriate procedure depends on:
-
Stone size
-
Stone location
-
Number of stones
-
Stone composition or density
-
Kidney anatomy
-
Urinary obstruction
-
Previous procedures
-
Overall health
Benefits of Laser Stone Removal
For appropriately selected patients, laser lithotripsy may offer several advantages.
Minimally Invasive Approach
The procedure is performed through the urinary tract and generally does not require a large surgical incision.
Effective Stone Fragmentation
Laser energy can fragment many types of urinary stones.
Useful for Difficult Stone Locations
Ureteroscopy can reach certain stones that may be difficult to treat using other approaches.
Stone Fragment Retrieval
Depending on the situation, stone fragments can be removed during the procedure.
Potentially Short Recovery
Many patients can return to normal activities relatively quickly, although recovery varies according to the procedure and individual health.
Is Laser Stone Removal Painful?
The procedure itself is generally performed under anesthesia, so patients typically do not experience the procedure in the usual way.
After treatment, some patients may experience:
-
Mild burning while urinating
-
Blood in the urine
-
Urinary frequency
-
Urinary urgency
-
Flank or bladder discomfort
-
Temporary discomfort related to a ureteral stent
These symptoms often improve as recovery progresses, but patients should follow their treating doctor's instructions.
Ureteral Stent After Laser Stone Removal
A ureteral stent may be placed temporarily after ureteroscopy and laser lithotripsy.
The stent helps maintain urine drainage from the kidney to the bladder.
Some people experience:
-
Frequent urination
-
Urgency
-
Burning during urination
-
Blood in the urine
-
Flank discomfort
-
Bladder discomfort
The stent is usually removed according to the treatment plan provided by the urologist.
Patients should not ignore severe pain, fever, or difficulty passing urine while a stent is in place.
Recovery After Laser Stone Removal
Recovery depends on the stone, procedure, stent placement, and overall health.
Patients are generally advised to:
-
Follow the urologist's instructions
-
Take prescribed medicines correctly
-
Drink fluids according to medical advice
-
Avoid strenuous activity for the recommended period
-
Attend the scheduled follow-up appointment
-
Return for stent removal when advised
-
Complete follow-up imaging when recommended
Recovery can vary from person to person.
Possible Risks and Complications
Laser stone removal is commonly used, but like any medical procedure, it has potential risks.
Possible complications include:
-
Urinary tract infection
-
Blood in the urine
-
Temporary urinary discomfort
-
Ureteral injury
-
Ureteral narrowing or stricture
-
Residual stone fragments
-
Need for another procedure
-
Stent-related discomfort
The risk depends on the patient's condition, stone characteristics, and complexity of treatment.
Laser Stone Removal and Infection
One of the most important considerations before stone treatment is whether a urinary infection is present.
A stone that blocks urine flow while infection is present can become a serious medical emergency.
If there is significant infection with obstruction, urgent drainage of the urinary system may be required before definitive stone removal.
Possible drainage methods include:
-
Ureteral stent
-
Percutaneous nephrostomy
Antibiotic treatment is also used when a bacterial infection is diagnosed or suspected.
Fever or chills associated with severe stone pain or difficulty passing urine requires urgent medical evaluation.
How Is the Need for Laser Treatment Decided?
Your doctor may evaluate:
Stone Size
Larger stones are less likely to pass naturally.
Stone Location
A stone in the kidney may have a different treatment approach from one located in the ureter.
Stone Density
Imaging characteristics can influence the choice between treatment options.
Symptoms
Persistent or severe pain may favor active treatment.
Obstruction
Urinary obstruction can threaten kidney function and may require timely intervention.
Infection
Infection changes the urgency and sequence of treatment.
Kidney Function
Patients with impaired kidney function require careful treatment planning.
Other Kidney Stone Treatment Options
Laser treatment is only one of several available approaches.
Observation and Medical Management
Some small stones may pass naturally with appropriate monitoring and medical treatment.
ESWL
Extracorporeal Shock Wave Lithotripsy (ESWL) uses externally generated shock waves to fragment selected kidney or ureteral stones.
RIRS
Retrograde Intrarenal Surgery (RIRS) uses a flexible ureteroscope to reach selected kidney stones and fragment them, often with laser energy.
PCNL
Percutaneous Nephrolithotomy (PCNL) is commonly used for larger or complex kidney stones and involves accessing the kidney through a small skin incision.
The best treatment depends on individual circumstances rather than stone size alone.
What Happens to the Stone After Laser Treatment?
Depending on the treatment strategy, the stone may be:
-
Broken into very small fragments
-
Removed using specialized instruments
-
Left as small fragments to pass naturally
-
Sent for laboratory analysis when appropriate
Stone analysis can be useful because knowing the stone type may help guide future prevention.
Can Kidney Stones Come Back After Laser Removal?
Yes. Laser treatment removes or fragments the existing stone, but it does not necessarily eliminate the underlying reason why stones formed.
Patients with recurrent stones may benefit from:
-
Stone analysis
-
Blood tests
-
Urine evaluation
-
Metabolic assessment
-
Dietary review
-
Increased fluid intake when appropriate
-
Stone-specific preventive medication when indicated
Long-term prevention is particularly important for people who repeatedly develop kidney stones.
How to Reduce the Risk of Future Kidney Stones
Depending on the stone type and medical condition, prevention may include:
-
Drinking adequate fluids as advised
-
Reducing excessive salt intake
-
Maintaining a balanced diet
-
Following stone-specific dietary recommendations
-
Managing body weight
-
Avoiding unnecessary supplements
-
Treating recurrent urinary infections
-
Taking prescribed preventive medicines
-
Attending follow-up appointments
Patients with chronic kidney disease or fluid restrictions should follow individualized fluid advice rather than increasing water intake on their own.

Frequently Asked Questions
Is laser treatment safe for kidney stones?
Laser lithotripsy is a commonly used treatment for selected kidney and ureteral stones. However, every procedure has potential risks, and suitability depends on the patient's individual condition.
Is laser better than ESWL?
Neither treatment is universally better. The choice depends on stone size, location, density, anatomy, obstruction, infection, previous treatment, and other patient-specific factors.
How long does laser stone removal take?
The duration varies depending on the number, size, location, and complexity of the stones and the treatment approach.
Will I need a stent after laser stone removal?
A temporary ureteral stent may be recommended in some patients. Whether a stent is needed depends on factors such as ureteral swelling, obstruction, stone characteristics, and the details of the procedure.
Can a kidney stone be completely removed with laser treatment?
In appropriately selected cases, stones can be fragmented and removed during ureteroscopy. Some small residual fragments may remain and pass naturally, and additional treatment may occasionally be necessary.
Can laser treatment prevent future kidney stones?
Laser treatment addresses the existing stone but does not necessarily prevent new stones. Identifying the stone type and addressing dietary or metabolic risk factors can help reduce recurrence.
Which doctor performs laser kidney stone removal?
Laser stone removal using ureteroscopy is generally performed by a urologist. A nephrologist can evaluate kidney function, recurrent stone risk, metabolic factors, and long-term prevention.
Conclusion
Laser for stone removal is an important minimally invasive option for selected kidney and ureteral stones. During ureteroscopy with laser lithotripsy, a urologist uses a thin endoscope to reach the stone and laser energy to fragment it into smaller pieces that can be removed or passed naturally.
