Overview
What is RIRS?
RIRS — Retrograde Intrarenal Surgery — is a minimally invasive endoscopic procedure for treating kidney stones. A thin, flexible telescope (flexible ureteroscope) is passed through the urethra, bladder, and ureter directly into the kidney — without making any cuts on the body.
Once inside the kidney, a Holmium laser is used to fragment the stone into fine dust or tiny pieces, which are then washed out naturally with urine or removed with tiny graspers. The result: complete stone clearance with virtually no recovery time.

The Procedure
How RIRS Works — Step by Step
01
AnaesthesiaPatient is given spinal or general anaesthesia — the procedure is completely painless.
02
Scope InsertionA thin flexible ureteroscope is gently passed through the urethra and bladder into the ureter and kidney.
03
Stone VisualisationThe stone is located inside the kidney using high-definition optics — precise targeting under direct vision.
04
Laser FragmentationA Holmium:YAG laser fibre is passed through the scope to break the stone into fine dust or small fragments.
05
Fragment RemovalLarger fragments are removed using a tiny basket; fine dust is flushed out naturally with urine.
06
Stent Placement (if needed)A temporary ureteric stent (DJ stent) may be placed to aid healing — removed in clinic after 1–2 weeks.
Ideal For
Which Stones Can RIRS Treat?
Kidney stones up to 2 cmBest results for stones in the 1–2cm range — high clearance rate with single sitting.
Multiple small stonesSeveral stones in the same kidney can be treated in a single procedure.
Lower pole stonesDifficult-to-treat stones at the bottom of the kidney — RIRS reaches where ESWL cannot.
Hard stones (Calcium Oxalate)Holmium laser effectively fragments even the hardest stone types.
Stones with poor ESWL responseWhen shockwave therapy has failed or is not suitable — RIRS is the next best step.
High-risk patientsObese patients, anticoagulated patients, or those who cannot tolerate open surgery.
Why Choose RIRS
Key Benefits of RIRS
Completely ScarlessNo incision anywhere on the body — natural passage only
Fast RecoveryReturn to normal activities within 2–3 days of procedure
Minimal PainFar less discomfort than PCNL or open surgery
High PrecisionDirect visual targeting of stone under HD optics
Day SurgeryDone under general/spinal anaesthesia, discharged next day
95%+ Stone-Free RateExcellent clearance for stones up to 2cm
Is RIRS Right for You?RIRS is best suited for kidney stones up to 2cm. For larger or staghorn stones, PCNL may be more appropriate. Dr. Ravi Nagar will evaluate your stone size, composition, location, and overall health to recommend the best procedure for your specific case.
