Introduction

Endoscopic surgery for kidney stones is a minimally invasive approach used to diagnose and remove stones from the urinary tract. Depending on the size, location, and number of stones, an endoscopic procedure may allow the stone to be removed or broken into smaller fragments without the need for a large surgical incision.

Kidney stones can cause severe flank or back pain, blood in the urine, nausea, vomiting, urinary discomfort, or urinary obstruction. While some small stones may pass naturally with appropriate medical treatment, larger, obstructing, or difficult-to-pass stones may require a procedure.

Common endoscopic techniques include ureteroscopy (URS) and retrograde intrarenal surgery (RIRS). During these procedures, a thin endoscope is passed through the natural urinary passage to reach the ureter or kidney. A laser or another suitable instrument can then be used to fragment and remove the stone.

At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive evaluation of kidney stones, kidney-function assessment, personalized treatment guidance, and coordination with experienced urology specialists when an endoscopic procedure is required.

What Is Endoscopic Surgery for Kidney Stones?

Endoscopic stone surgery is a minimally invasive procedure in which a specialized instrument called an endoscope is used to access stones through the urinary tract.

Unlike traditional open surgery, endoscopic stone procedures generally do not require a large external incision.

Depending on the stone's location, the procedure may involve:

Ureteroscopy (URS)
Laser lithotripsy
Retrograde intrarenal surgery (RIRS)
Stone extraction using specialized instruments
Temporary ureteral stent placement when required

The appropriate technique depends on the individual patient's stone characteristics and overall health.

When Is Endoscopic Surgery Recommended?

Not every kidney stone requires surgery.

Small stones may sometimes pass naturally with medical management. Endoscopic treatment may be considered when a stone:

Is too large to pass naturally
Causes persistent or severe pain
Blocks urine flow
Causes recurrent urinary infections
Causes kidney swelling or hydronephrosis
Does not pass with conservative treatment
Causes worsening kidney function
Is located in a position where spontaneous passage is unlikely
Requires active removal based on clinical circumstances

A urologist evaluates the stone and determines whether endoscopic treatment is appropriate.

Types of Endoscopic Kidney Stone Procedures

Ureteroscopy (URS)

Ureteroscopy is commonly used for stones located in the ureter or selected kidney stones.

A thin ureteroscope is passed through:

Urethra → Bladder → Ureter

The surgeon identifies the stone and may:

Remove it with a retrieval basket
Break it into smaller fragments
Use laser lithotripsy to fragment the stone

Retrograde Intrarenal Surgery (RIRS)

RIRS is an advanced endoscopic technique used to treat stones located inside the kidney.

A flexible ureteroscope is passed through the urinary tract into the kidney.

The surgeon can visualize the stone and use a laser to break it into smaller fragments.

RIRS may be considered for selected kidney stones depending on their:

Size
Location
Number
Composition
Anatomical position

Laser Lithotripsy

Laser lithotripsy uses laser energy to break a kidney or ureteric stone into smaller pieces.

The fragments may then:

Be removed with a basket
Pass naturally in the urine
Be reduced to very small particles, depending on the surgical technique

The choice of laser technique depends on the stone and the surgeon's assessment.

How Is Endoscopic Kidney Stone Surgery Performed?

The exact steps vary according to the procedure.

Step 1: Preoperative Evaluation

Before surgery, the patient may undergo:

Medical history
Physical examination
Blood tests
Urine tests
Kidney-function testing
Imaging such as ultrasound or CT scan

If a urinary infection is suspected, it should be appropriately evaluated and treated before elective stone surgery.

Step 2: Anesthesia

Endoscopic kidney stone procedures are generally performed under anesthesia so that the patient does not experience procedural pain.

The type of anesthesia depends on the procedure and the patient's medical condition.

Step 3: Endoscope Insertion

The endoscope is carefully passed through the natural urinary passage.

No large external incision is usually required.

Step 4: Stone Identification

The surgeon uses the endoscope's camera to locate the stone.

Step 5: Stone Fragmentation or Removal

Depending on the stone, the surgeon may use:

Laser lithotripsy
Retrieval basket
Other specialized instruments

The goal is to remove the stone or break it into fragments that can be safely cleared.

Step 6: Ureteral Stent Placement

A temporary ureteral stent may be placed after the procedure when clinically necessary.

A stent can help:

Maintain urine flow
Reduce the risk of obstruction from swelling or fragments
Support healing of the ureter

The stent is usually removed later according to the treating urologist's instructions.

Benefits of Endoscopic Surgery for Kidney Stones

Endoscopic treatment can offer several advantages for appropriately selected patients.

Minimally Invasive

The procedure is performed through the urinary tract rather than through a large surgical incision.

Effective Stone Removal

Many ureter and kidney stones can be treated effectively using ureteroscopy or RIRS.

No Large External Incision

Because the urinary tract is used to reach the stone, external surgical wounds are generally minimal.

Suitable for Selected Difficult Stones

Endoscopic techniques can be useful for stones that are unlikely to pass naturally or that have not responded to other treatments.

Targeted Treatment

The surgeon can directly visualize the stone and treat it precisely.

Is Endoscopic Surgery Better Than Other Kidney Stone Treatments?

There is no single best treatment for every kidney stone.

Treatment depends on:

Stone size
Stone location
Number of stones
Stone composition
Kidney anatomy
Symptoms
Urinary obstruction
Infection
Previous treatment
Overall health

Other treatment options may include:

Medical expulsive therapy for selected stones
Extracorporeal shock wave lithotripsy (ESWL)
Percutaneous nephrolithotomy (PCNL)
Observation in selected cases

A urologist determines the most appropriate procedure after reviewing imaging and clinical findings.

Endoscopic Surgery vs ESWL

Both procedures can be useful for selected kidney stones, but they work differently.

Endoscopic Surgery

Uses an endoscope to reach the stone
May use laser fragmentation
Allows direct visualization
Often used for ureteric and selected kidney stones

ESWL

Uses shock waves from outside the body
Breaks the stone into smaller fragments
Does not require an endoscope
Effectiveness depends on stone size, location, composition, and patient factors

The appropriate option should be selected after specialist evaluation.

Endoscopic Surgery vs PCNL

For larger kidney stones, percutaneous nephrolithotomy (PCNL) may sometimes be preferred.

PCNL involves accessing the kidney through a small tract created through the skin.

Compared with RIRS:

RIRS reaches the kidney through the urinary tract.
PCNL reaches the kidney through a small skin incision.
PCNL is commonly considered for larger or complex stone burdens.

The choice depends on the stone's size, location, anatomy, and other clinical factors.

Risks and Possible Complications

Endoscopic kidney stone surgery is generally considered minimally invasive, but like any procedure, it can have risks.

Possible complications include:

Blood in the urine
Urinary discomfort
Urinary infection
Fever
Ureteral injury
Temporary swelling
Residual stone fragments
Need for another procedure
Stent-related discomfort
Rare ureteral stricture

Your urologist will discuss the potential risks and expected benefits before the procedure.

Recovery After Endoscopic Kidney Stone Surgery

Recovery varies depending on the procedure and individual health.

Patients may experience temporary:

Mild flank discomfort
Burning while urinating
Increased urinary frequency
Blood-tinged urine
Stent-related discomfort

Your doctor may recommend:

Adequate fluid intake when medically appropriate
Prescribed medications
Avoiding strenuous activity for a specified period
Follow-up imaging
Stent removal at the recommended time
Stone analysis when appropriate

Patients with fluid restrictions because of kidney, heart, or other medical conditions should follow their doctor's individualized fluid recommendations.

What Happens If a Stent Is Placed?

A ureteral stent is a thin tube placed between the kidney and bladder.

Some patients experience:

Urinary frequency
Urgency
Mild flank discomfort
Bladder discomfort
Blood in the urine

These symptoms often improve after stent removal.

The stent should be removed according to the schedule provided by the treating urologist.

Warning Signs After Stone Surgery

Contact your healthcare team promptly if you develop:

High fever
Chills
Severe or worsening pain
Persistent vomiting
Difficulty passing urine
Very low urine output
Heavy or persistent blood in the urine
Severe weakness

Fever after urinary stone surgery can sometimes indicate an infection and should be assessed promptly.

How to Prevent Kidney Stones After Surgery

Removing a stone does not always prevent future stones.

Stone prevention may involve:

Adequate fluid intake when medically appropriate
Reducing excessive salt intake
Maintaining a balanced diet
Stone analysis
Metabolic evaluation in recurrent stone formers
Managing calcium, uric acid, or other metabolic risk factors
Following individualized dietary advice

Patients with recurrent kidney stones may benefit from a detailed evaluation to identify why stones are forming.

How Is a Kidney Stone Evaluated Before Surgery?

At Prabhakar Bhurke Clinic, our super specialist nephrologist may recommend evaluation including:

Blood Tests

Serum creatinine
eGFR
Electrolytes
Calcium
Uric acid
Other tests when indicated

Urine Tests

Urinalysis
Urine culture when infection is suspected
Urine protein testing when clinically appropriate
Metabolic stone evaluation for recurrent stone formers

Imaging

Depending on the situation:

Kidney ultrasound
CT scan
X-ray when appropriate

Imaging helps determine stone size, location, number, and possible urinary obstruction.

Frequently Asked Questions (FAQs)

What is endoscopic surgery for kidney stones?

Endoscopic surgery uses a thin instrument called an endoscope to reach stones through the urinary tract. The stone may be removed or fragmented using techniques such as laser lithotripsy.

Is endoscopic kidney stone surgery painful?

The procedure is generally performed under anesthesia. Temporary discomfort, urinary burning, or flank discomfort can occur during recovery, particularly when a stent is placed.

How long does endoscopic kidney stone surgery take?

The duration varies depending on the stone's size, number, location, anatomy, and procedure performed. Your urologist can provide an individualized estimate.

Is a stent always required?

No. A stent is not required in every case. The decision depends on factors such as ureteral swelling, obstruction, infection risk, residual fragments, and the complexity of the procedure.

Can all kidney stones be removed endoscopically?

No. The best treatment depends on stone size, location, number, anatomy, and other clinical factors. Some larger or complex stones may be better treated with PCNL or another approach.

Is RIRS an endoscopic procedure?

Yes. RIRS is an endoscopic technique in which a flexible ureteroscope is passed through the urinary tract to reach stones inside the kidney.

Can kidney stones come back after surgery?

Yes. Stone removal treats the existing stone but does not necessarily eliminate the factors that caused it. Metabolic evaluation and preventive measures can help reduce recurrence.

Conclusion
