Laser Lithotripsy(RIRS)
Retrograde Intrarenal Surgery (RIRS) is an advanced, minimally invasive procedure used to treat kidney stones located in the upper urinary tract, especially within the kidney.
overview
In this technique, a flexible ureteroscope is passed through the urethra, bladder, and ureter, and into the kidney—without any external incision. Once the stone is visualized, a high-powered Holmium laser is used to break the stone into fine dust or tiny fragments, a process known as laser lithotripsy.
RIRS is especially useful for treating stones that are too large for spontaneous passage but not suitable for shockwave therapy (ESWL), or when other methods have failed. It’s also ideal for patients who cannot undergo open or percutaneous surgery due to medical reasons.
Symptoms & Diagnosis
The entire procedure is done under general anesthesia. After the stone is broken, the tiny fragments are either removed using a basket or left to pass naturally in the urine. A double-J stent is often placed temporarily to ensure smooth urine drainage and prevent ureteral swelling.
Advantages of RIRS:
- No surgical cuts or external scars.
- Minimal bleeding and pain.
- Short hospital stay (often 24 hours).
- Quick recovery and return to normal activity.
- Safe and effective for most kidney stones.
