Home > RIRS (Retrograde Intrarenal Surgery)

Overview

Retrograde Intrarenal Surgery (RIRS) is a minimally invasive procedure used to treat kidney stones and certain kidney conditions. It involves passing a flexible ureteroscope through the urinary tract (without any cuts on the body) to access the kidney. Using a laser, stones are broken into fine dust and removed, allowing safe and scarless treatment.

What is RIRS?

RIRS is a keyhole, scarless surgery where a flexible ureteroscope is passed through the urethra and bladder into the kidney. A laser is then used to break and remove kidney stones or treat other intrarenal conditions.

When is RIRS recommended?

RIRS is advised for patients with:

  • Kidney stones too large or hard for medications or ESWL (shockwave therapy)
  • Stones in difficult-to-reach areas of the kidney
  • Recurrent stones needing minimally invasive treatment
  • Patients unfit for open or percutaneous (PCNL) surgery
Is RIRS safe?

Yes. RIRS is safe and highly effective when performed by expert urologists. Risks like urinary infection, bleeding, or ureteral injury are rare and manageable.

What is the recovery like after RIRS?
  • Most patients go home within 24–48 hours
  • Minimal pain compared to other surgeries
  • Return to routine activities in 3–5 days
  • Stents may be placed temporarily to help urine flow and are removed later
What size stones can RIRS treat?

RIRS can treat stones up to 2 cm effectively. For larger stones, PCNL may be recommended, but RIRS remains an option in selected cases.

How does RIRS compare to other kidney stone treatments?
  • RIRS: Minimally invasive, scarless, faster recovery
  • PCNL: Recommended for very large stones; more invasive
  • ESWL: Uses shockwaves, but not effective for all stones

Choice depends on stone size, location, and patient profile.

Can kidney stones come back after RIRS?

Yes, kidney stones can recur due to metabolic or dietary factors. Preventive steps include hydration, dietary modifications, and regular follow-ups with a urologist.
