RIRS Surgery
Retrograde Intrarenal Surgery (RIRS) is a minimally invasive procedure used to treat kidney stones and other abnormalities in the kidney. It involves the use of a flexible ureteroscope to access the kidney through the urinary tract, without making any external incisions. RIRS is ideal for patients with smaller stones or stones located in difficult-to-access areas of the kidney.
Indications for RIRS
RIRS is commonly recommended for:
- Kidney stones smaller than 2 cm in diameter.
- Stones located in the renal pelvis or calyces that are not easily reachable by other methods.
- Stones in patients with bleeding disorders where other surgical techniques pose higher risks.
- Residual stones after other procedures like PCNL or ESWL.
- Cases where other treatments, such as ESWL or ureteroscopy, have failed.
Procedure Details
Preoperative Preparation:
- Patients undergo imaging studies like a CT scan or X-ray to assess the location and size of the kidney stones.
- General or spinal anesthesia is administered to ensure patient comfort.
- Antibiotics may be given to reduce the risk of infection.
Access to the Kidney:
- A flexible ureteroscope is inserted through the urethra, bladder, and ureter to reach the kidney.
- No incisions are made during this procedure.
Stone Removal:
- The ureteroscope allows direct visualization of the stone.
- Laser energy, typically using a Holmium:YAG laser, is used to break the stones into smaller fragments.
- Smaller fragments are either removed with specialized tools or allowed to pass naturally through the urine.
Post-Procedure Care:
- A ureteral stent may be placed temporarily to prevent obstruction and aid in healing.
Benefits of RIRS
- Minimally Invasive: No external incisions are required, reducing recovery time and post-surgical discomfort.
- High Precision: The ureteroscope provides excellent visualization of the kidney, allowing for precise stone removal.
- Quick Recovery: Most patients can return to their normal activities within a few days.
- Versatile: Effective for stones in difficult-to-reach areas or for patients unsuitable for other procedures.
Comparison with Other Treatments
- PCNL (Percutaneous Nephrolithotomy): Used for larger stones, involves a small incision.
- ESWL (Extracorporeal Shock Wave Lithotripsy): Non-invasive but less effective for stones in certain locations or dense stones.
- Ureteroscopy: Similar to RIRS but usually used for stones in the ureter rather than the kidney.
Why Choose RIRS?
- Safe and Effective: Particularly for small or medium-sized stones.
- No External Cuts: Reduces the risk of scarring and infection.
- Quick Return to Normal Life: Minimal downtime compared to other surgical options.

Recovery and Aftercare
- Hospital Stay: Most patients are discharged the same day or after an overnight stay.
- Pain Management: Mild discomfort is common and can be managed with painkillers.
- Follow-Up: A follow-up appointment may include imaging to confirm that all stones have been removed.
- Activity: Patients are advised to avoid strenuous activities for a week.
Who Performs RIRS?
RIRS is typically performed by a skilled urologist specializing in minimally invasive kidney stone treatments. The procedure requires advanced equipment, including a flexible ureteroscope and a Holmium laser.
