RIRS (Retrograde Intrarenal Surgery) | Dr. S K Palash
Kidney stones can cause excruciating pain, urinary discomfort, and in some cases, complications if left untreated. While traditional surgical options are still used, modern urology offers a more advanced and minimally invasive solution known as RIRS (Retrograde Intrarenal Surgery)—a game-changer in the treatment of kidney stones.
At his clinic in Baner, Pune, Dr. S. K. Palash, an experienced Urologist & Laser Stone Surgeon, offers Advanced RIRS for safe, effective, and scarless kidney stone removal.
What is RIRS?
RIRS (Retrograde Intrarenal Surgery) is a minimally invasive laser procedure used to remove kidney stones located in the kidney or upper ureter. It involves the use of a thin, flexible ureteroscope passed through the urethra and bladder into the kidney—without any cut or incision.
Once the stone is visualized, it is fragmented using a specialized laser—typically Holmium or Thulium laser—and the tiny fragments are either removed or left to pass naturally through urine.
When is RIRS Recommended?
RIRS is especially useful in cases where:
Kidney stones are smaller than 2 cm
Stones are located in hard-to-reach areas like the lower pole calyx
Shock Wave Lithotripsy (ESWL) or medical expulsion therapy has failed
Patients have bleeding disorders or obesity, making open surgery riskier
Pediatric patients or those with a single kidney require a safer alternative
Dr. S.K. Palash carefully evaluates the size, number, and location of the stones before recommending RIRS.
Is RIRS a Painful Procedure?
RIRS is typically performed under general or spinal anesthesia, which ensures the procedure is pain-free. Postoperative pain is usually minimal, and most patients can resume their routine activities within a few days.
How is RIRS Performed?
The steps of the RIRS procedure include:
A flexible ureteroscope is gently inserted through the urethra, bladder, and into the ureter and kidney.
The kidney stone is visualized directly.
A laser is used to break the stone into smaller pieces.
Fragments are either removed or left to pass naturally.
A DJ stent (Double J stent) is typically placed to aid urine flow and healing.
Duration and Recovery
Procedure time: Usually 45 to 90 minutes, depending on the stone’s size and location.
Hospital stay: Most patients are discharged within 24 hours.
Recovery: You can expect to return to normal activities in 2–3 days, with complete recovery within a week.
Is a Stent Always Required?
Yes, in most cases, a temporary DJ stent is placed after RIRS to:
Prevent swelling or blockage in the ureter
Ensure smooth urine flow post-surgery
The stent is usually removed after 1–2 weeks during a follow-up visit.
Benefits of RIRS
RIRS is gaining popularity due to its many advantages:
No external incision or scar
Quick recovery and short hospital stay
Minimal blood loss
Highly effective for small to medium-sized stones
Safe for high-risk patients, including children and those with bleeding disorders
Are There Any Risks?
Though RIRS is generally safe, like any medical procedure, it may have some rare complications, such as:
Mild urinary tract infection
Burning urination or temporary fever
Bleeding (minimal)
Ureteral injury or stricture (very rare)
Repeat procedure if there are multiple or particularly hard stones
Dr. S.K. Palash ensures comprehensive pre-operative planning and post-operative care to minimize such risks.
RIRS vs. PCNL – Which is Better?
While RIRS is excellent for smaller or mid-sized stones, PCNL (Percutaneous Nephrolithotomy) is preferred for larger stones (>2 cm) or complex staghorn calculi. The choice depends on various factors like stone size, location, and patient health conditions—which your urologist will assess thoroughly.
If you're struggling with kidney stones and looking for a painless, scarless, and effective solution, RIRS might be the right option for you. It offers quick recovery, minimal discomfort, and excellent results with the right expertise.
