Ureteroscopy (URS) and Retrograde Intrarenal Surgery (RIRS) are advanced, minimally invasive procedures designed to treat kidney and ureteral stones. If you're experiencing the discomfort of kidney stones and seeking an effective solution, these techniques offer a precise and often immediate pathway to relief.
Both URS and RIRS involve navigating a flexible scope through your natural urinary passages · the urethra and bladder · to reach stones located in the ureter or within the kidney itself. Once the stone is located, a holmium laser is used to either fragment it into tiny pieces that can pass naturally or dust it into fine particles.
These procedures are performed without any external incisions, meaning no cuts to your skin. This translates to less pain, a quicker recovery, and minimal scarring, allowing you to return to your normal activities sooner.
This guide will explain how URS and RIRS work, who they are best suited for, their benefits, how they compare to other stone treatments, and what you can expect during recovery.
What Are Ureteroscopy (URS) and Retrograde Intrarenal Surgery (RIRS)?
URS and RIRS are endoscopic procedures used to treat stones in the ureter (the tube connecting the kidney to the bladder) or within the kidney. The key difference lies in how far the scope travels: URS typically addresses stones in the ureter, while RIRS involves guiding a more flexible scope further into the kidney's collecting system.
How URS and RIRS work:
You will receive either spinal or general anesthesia.
A thin, flexible ureteroscope is inserted through your urethra and bladder.
The scope is carefully advanced up the ureter to locate the stone.
For RIRS, the flexible scope is guided further into the kidney.
A holmium laser fiber is passed through the scope to fragment or dust the stone.
Stone fragments may be removed with a small basket or allowed to pass naturally.
Often, a temporary double-J stent is placed in the ureter to keep it open during healing.
The procedure is performed entirely through your natural urinary tract, with no external incisions.
Who Are URS and RIRS For?
URS and RIRS are excellent choices for men with:
Stones in the ureter that are causing pain or obstruction.
Kidney stones, especially those in the lower pole of the kidney, which can be challenging for other treatments.
Hard stones (high Hounsfield units) that are less likely to respond to ESWL.
Stones that have failed to break up with ESWL (Extracorporeal Shockwave Lithotripsy).
Stones larger than 1.5 cm but smaller than 2 cm, where PCNL might be too invasive.
Individuals who cannot undergo ESWL due to medical conditions or anticoagulant use.
Benefits of URS and RIRS
1. No External Incisions
Both procedures are performed entirely through your natural urinary tract, meaning no cuts to your skin and minimal scarring.
2. High Success Rate
URS and RIRS offer high stone-free rates, especially for stones that are difficult to treat with other methods.
3. Effective for Hard Stones
The holmium laser is highly effective at breaking down even very hard stones that might resist shockwave therapy.
4. Direct Visualization
Your surgeon can directly visualize the stone, ensuring precise targeting and complete removal or fragmentation.
5. Quick Recovery
Most patients experience a rapid recovery, often returning home the same day or after a single night's stay.
How URS and RIRS Compare to Other Stone Treatments
**Extracorporeal Shockwave Lithotripsy (ESWL):** ESWL is non-invasive, using shockwaves from outside the body to break stones. It's generally better for softer, smaller stones (under 1.5 cm) and those located in the upper or middle kidney. URS/RIRS offer direct visualization and are more effective for harder stones, lower ureteric stones, and lower-pole kidney stones.
**Percutaneous Nephrolithotomy (PCNL):** PCNL is a more invasive surgical procedure involving a small incision in your back to access and remove very large kidney stones (typically over 2 cm). URS/RIRS are less invasive and preferred for smaller to medium-sized stones, avoiding the need for an external incision.
Recovery After URS and RIRS
**Day 0:** Procedure completed. You may go home the same day or stay one night in the hospital.
**Days 1-2:** You might experience some discomfort, blood in your urine, and frequent urination. Pain medication will be prescribed.
**Week 1-2:** If a double-J stent was placed, you might feel a sensation of needing to urinate frequently or mild flank pain. The stent is typically removed in an outpatient procedure after 1-2 weeks.
**Week 2-4:** Most individuals can return to light activities and desk work. Avoid strenuous exercise until your doctor advises.
**Week 4-6:** Full activity can usually be resumed once the stent is removed and your doctor confirms healing.
Risks and Side Effects
While URS and RIRS are safe and effective, like any medical procedure, they carry some potential risks and side effects:
Blood in urine (hematuria)
Urinary tract infection (UTI)
Ureteral injury or perforation (rare)
Stent-related discomfort (common if a stent is placed)
Stone fragments remaining (requiring further treatment in some cases)
Temporary swelling of the ureter
Your urologist will discuss these risks with you in detail before your procedure.
