Introduction
RIRS surgery for kidney stone is a minimally invasive procedure used to treat kidney stones, particularly stones that may be difficult to remove with medicines or other non-invasive treatments.
RIRS stands for Retrograde Intrarenal Surgery. During the procedure, a urologist uses a thin flexible ureteroscope to reach the kidney through the natural urinary passage. A laser may then be used to break the stone into smaller fragments or dust that can be removed or passed through urine.
Compared with traditional open surgery, RIRS does not usually require a large incision. The procedure is commonly considered for selected kidney stones based on their size, location, number, hardness, anatomy of the urinary tract, and the patient's overall health.
At Prabhakar Bhurke Clinic, our super specialist nephrologist provides comprehensive kidney evaluation and medical management for patients with kidney stones, recurrent stones, kidney-function abnormalities, and related kidney conditions. When a stone requires a surgical procedure, care may be coordinated with an experienced urologist.
What Is RIRS Surgery?
Retrograde Intrarenal Surgery (RIRS) is a minimally invasive endoscopic procedure for treating stones located inside the kidney.
Unlike procedures that require an incision through the skin, RIRS generally accesses the urinary system through:
Urethra → Bladder → Ureter → Kidney
A flexible ureteroscope allows the urologist to visualize the stone inside the kidney.
A laser can then fragment or dust the stone.
When Is RIRS Recommended?
RIRS may be considered when:
-
A kidney stone is unlikely to pass naturally
-
The stone is causing recurrent pain
-
The stone causes urinary obstruction
-
The stone is associated with recurrent infections
-
Previous stone treatment has not been successful
-
The stone's size or location makes another treatment less suitable
-
The patient has multiple or complex kidney stones
The appropriate treatment depends on the individual patient.
RIRS for Different Kidney Stone Sizes
Treatment selection depends on more than stone size alone.
Factors include:
-
Stone diameter
-
Stone location
-
Number of stones
-
Stone composition
-
Kidney anatomy
-
Urinary tract anatomy
-
Presence of obstruction
-
Infection
-
Previous procedures
-
Overall kidney function
For some stones, shock wave lithotripsy (ESWL) or other approaches may be appropriate. Larger or complex stones may require procedures such as PCNL.
A urologist evaluates the stone and recommends the most suitable procedure.
How Is RIRS Surgery Performed?
1. Preoperative Evaluation
Before RIRS, the doctor may recommend:
-
Urine examination
-
Urine culture
-
Blood tests
-
Serum creatinine
-
Kidney-function tests
-
Imaging such as CT or ultrasound
If a urinary infection is present, it generally needs appropriate treatment before elective stone removal.
2. Anesthesia
RIRS is usually performed under anesthesia so the patient remains comfortable during the procedure.
3. Ureteroscope Insertion
A thin flexible ureteroscope is passed through the urinary passage into the ureter and kidney.
No large external incision is usually required.
4. Stone Visualization
The surgeon identifies the stone using the camera at the tip of the ureteroscope.
5. Laser Stone Fragmentation
A laser may be used to:
-
Break the stone into smaller fragments
-
Dust the stone into fine particles
-
Facilitate removal of larger fragments
6. Stone Fragment Removal
Small stone fragments may be removed using specialized instruments, while very small fragments may pass naturally through urine.
7. Ureteric Stent
In some patients, a temporary ureteric stent may be placed to help urine drain and support healing.
The stent is usually removed later according to the treating urologist's instructions.
Benefits of RIRS Surgery for Kidney Stones
For appropriately selected patients, RIRS may provide several advantages:
-
Minimally invasive approach
-
No large surgical incision
-
Treatment of stones inside the kidney
-
Ability to reach stones in different kidney locations
-
Useful for selected stones that are difficult to treat with other methods
-
Relatively short recovery compared with open stone surgery
The expected result depends on stone size, number, location, composition, and patient anatomy.
RIRS vs ESWL
Both RIRS and ESWL can be used for selected kidney stones, but they work differently.
RIRS
-
Uses a flexible ureteroscope
-
Reaches the stone directly
-
Uses laser energy to fragment the stone
-
Usually requires anesthesia
-
May be preferred for selected stones based on size and location
ESWL
-
Uses shock waves from outside the body
-
Breaks the stone into smaller pieces
-
Does not require an endoscope to enter the urinary tract
-
Effectiveness depends on stone size, location, composition, and other factors
The urologist chooses the most appropriate treatment based on the individual stone and patient.
RIRS vs PCNL
PCNL (Percutaneous Nephrolithotomy) is another minimally invasive procedure used particularly for larger or complex kidney stones.
RIRS
The stone is reached through the natural urinary passage.
PCNL
A small tract is created through the skin directly into the kidney.
PCNL may be preferred for certain large or complex stones, while RIRS may be appropriate for selected smaller or moderately sized stones.
Treatment should be individualized.
Possible Risks and Complications of RIRS
Although RIRS is minimally invasive, complications can occur.
Possible risks include:
-
Urinary tract infection
-
Bleeding
-
Temporary blood in urine
-
Ureteric injury
-
Ureteric swelling
-
Stone fragments remaining in the kidney
-
Need for repeat treatment
-
Stent-related discomfort
-
Rare ureteric narrowing or other complications
The risk varies according to the patient's condition and the complexity of the procedure.
RIRS and Kidney Function
Kidney function is an important consideration when treating kidney stones.
Untreated obstruction, repeated infections, or recurrent stones may affect kidney function in some patients.
Patients with:
-
High creatinine
-
Low eGFR
-
A single functioning kidney
-
Recurrent kidney stones
-
Kidney disease
may require additional kidney-function assessment.
At Prabhakar Bhurke Clinic, our super specialist nephrologist can evaluate kidney function and help manage medical kidney conditions before and after stone treatment.
Recovery After RIRS
Recovery varies from patient to patient.
Temporary symptoms may include:
-
Mild burning during urination
-
Frequent urination
-
Blood in the urine
-
Flank discomfort
-
Stent-related urinary symptoms
Patients should follow the treating urologist's instructions regarding:
-
Medications
-
Hydration
-
Physical activity
-
Stent removal
-
Follow-up imaging
Severe pain, fever, chills, inability to pass urine, or worsening symptoms require prompt medical attention.
How to Prevent Kidney Stones After RIRS
Stone removal does not always prevent future stones.
Preventive care may include:
-
Drinking fluids according to medical advice
-
Reducing excessive salt intake
-
Maintaining a balanced diet
-
Avoiding excessive intake of certain stone-forming foods when medically indicated
-
Maintaining a healthy body weight
-
Treating urinary infections
-
Completing metabolic stone evaluation when recommended
-
Following stone-specific dietary advice
The best prevention strategy depends on the type of kidney stone.
Stone Analysis and Metabolic Evaluation
After stone treatment, the doctor may recommend analyzing the stone to determine its composition.
Depending on the patient's history, additional evaluation may include:
-
Blood tests
-
Urine studies
-
24-hour urine collection
-
Assessment of calcium and other metabolic factors
Understanding why stones form can help reduce the risk of recurrence.

Frequently Asked Questions (FAQs)
What is RIRS surgery for kidney stones?
RIRS, or Retrograde Intrarenal Surgery, is a minimally invasive procedure in which a flexible ureteroscope is passed through the urinary tract into the kidney to locate and treat stones, often using laser energy.
Is RIRS better than ESWL?
Neither procedure is universally better. The appropriate choice depends on stone size, location, composition, kidney anatomy, and patient factors.
Is RIRS painful?
The procedure is performed under anesthesia. Some patients may experience temporary discomfort, burning during urination, or flank pain during recovery, particularly when a ureteric stent is present.
How long does recovery after RIRS take?
Recovery varies depending on the procedure and patient. Many patients can gradually return to normal activities after a relatively short recovery period, following their urologist's instructions.
Can kidney stones come back after RIRS?
Yes. RIRS removes existing stones but does not necessarily eliminate the underlying tendency to form stones. Preventive evaluation and lifestyle changes can help reduce recurrence.
Who performs RIRS surgery?
RIRS is generally performed by a trained urologist. A nephrologist can evaluate kidney function, manage associated kidney disease, and help with long-term kidney health.
Conclusion
RIRS surgery for kidney stone is an advanced minimally invasive procedure that allows selected kidney stones to be treated through the natural urinary passage. Using a flexible ureteroscope and, when appropriate, laser technology, the urologist can fragment and remove kidney stones without the large incision associated with traditional open surgery.
The best treatment depends on stone size, location, number, composition, urinary anatomy, infection status, and kidney function. RIRS, ESWL, PCNL, and other treatment options may each have a role in appropriately selected patients.
