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.
