Retrograde Intrarenal Surgery (RIRS) is a sophisticated, minimally invasive surgical procedure performed entirely within the kidney using highly advanced fiberoptic tools. This technique has revolutionized the treatment of kidney stones, especially those deemed too complex for non-invasive treatments or too small for PCNL (Percutaneous Nephrolithotomy).
At The Optimum Clinic, we utilize RIRS as part of our commitment to providing patients with rapid recovery and effective stone clearance. This procedure is typically performed under general or spinal anesthesia, ensuring maximum patient comfort.
The process begins when a thin, flexible viewing tube, known as a flexible ureteroscopy (a type of fiberoptic endoscope), is carefully placed via the urethra, passing through the bladder and up the ureter. The instrument is then maneuvered into the kidney's collecting system, allowing the surgeon to reach virtually every part of the kidney where stones may reside.
This approach is what makes Retrograde Intrarenal Surgery so versatile: the endoscope is moved "retrograde" (upwards against the flow of urine) into a specific position within the kidney, allowing direct visualization of the stone or a small tumor.
Once the stone is precisely visualized through the flexible ureteroscopy, fragmentation is performed using the most advanced technology available: laser energy.
Retrograde Intrarenal Surgery with laser lithotripsy is highly effective because the laser probe can be accurately positioned right next to the stone. The laser (typically Holmium YAG) then evaporates the stone or fragments it into dust-like particles that can be passed naturally or retrieved using specialized baskets. In certain cases, small forceps may be used to grab pieces directly.
This focused technique ensures excellent stone clearance while preserving surrounding kidney tissue.
Retrograde Intrarenal Surgery (RIRS) offers several major advantages over other, more invasive surgical options for kidney stone removal:
Access to All Areas: The use of a flexible ureteroscopy grants access to all parts of the kidney, including hard-to-reach areas like the lower poles, that may be difficult to treat with traditional approaches.
Minimal Invasion: Since no incision is required, there is significantly less pain and bleeding following the surgery.
Rapid Recovery: Patients typically benefit from a faster recovery and shorter hospital stay, often returning to normal activities quickly.
Retrograde Intrarenal Surgery is often the recommended treatment for patients in several complex or specific circumstances:
Moderately Sized Stones: Used for kidney stones that are 1.5 cm to 2 cm, or multiple smaller stones.
Complex Anatomy: Recommended for patients with odd kidney anatomy, such as transplanted kidneys or horseshoe kidneys.
Specific Patient Profiles: Ideal for patients suffering from bleeding disorders, those with gross obesity, or stones found in children.
Failed Treatments: RIRS is the next step when previous treatment attempts, particularly ESWL, have completely failed to clear the stones.
Associated Conditions: Used in certain cases to address strictures, narrowing of the kidney outlet, or small tumors within the kidney.
