Ureteroscopy and RIRS · Endoscopic Kidney Stone Surgery in Bangkok
URS (Ureteroscopy) and RIRS (Retrograde Intrarenal Surgery) use a thin flexible scope passed up through the urethra to reach stones in the ureter or kidney. The stone is fragmented with a holmium laser and removed under direct vision. No external incisions, no skin puncture · the most patient-friendly option for stones that don’t respond to ESWL.

What Happens During Ureteroscopy / RIRS
Anesthesia
Spinal or general anesthesia.Scope insertion
A thin flexible ureteroscope is passed through the urethra and bladder into the ureter or kidney.Stone visualization
The stone is found under direct vision and assessed.Laser fragmentation
A holmium laser passed through the scope breaks the stone into small fragments or dust.Fragment removal or wash-out
Larger fragments are removed with a basket · dust is washed out with irrigation.Stent placement (often)
A double-J ureteric stent is often left for 1-2 weeks to keep the ureter open during healing · removed in a brief follow-up procedure.

Modern Flexible Scopes
Our urology team uses current-generation single-use and reusable flexible ureteroscopes · better visualization, better outcomes than older fiber-optic systems.
Holmium Laser Dusting
High-frequency holmium laser settings allow precise dust-mode lithotripsy · less stent time and less postoperative discomfort than basket-and-fragment approaches.
Stone-Strategy Triage
For each patient we choose ESWL, URS/RIRS, or PCNL based on stone size, location, density, and your anatomy · not a one-size-fits-all approach.
Private, Discreet Recovery
Confidential care, WhatsApp recovery support, English-language follow-up.
Frequently asked questions
What’s the difference between URS and RIRS?
URS (Ureteroscopy) refers to scope-based treatment in the ureter. RIRS (Retrograde Intrarenal Surgery) refers to the same scope reaching up into the kidney itself. The scope and laser are the same · only the anatomical target differs.
When is URS/RIRS better than ESWL?
URS/RIRS is better for hard stones (high Hounsfield units), lower ureteric stones, lower-pole kidney stones, or when ESWL has already failed. ESWL is non-invasive and preferred for stones under 2 cm that aren’t in unfavorable locations.
Why do I need a stent after?
A double-J ureteric stent keeps the ureter open while it heals from any swelling caused by stone passage or the scope. Most patients have the stent removed in a brief clinic procedure 1-2 weeks later. Some patients don’t need a stent at all.
How long is the recovery?
Most patients return to normal activity within 1-2 days. If a stent is in place, mild urinary frequency or discomfort is common until removal.
How much does URS/RIRS cost in Bangkok?
Cost depends on stone burden, anesthesia choice, scope type used, and whether a stent is placed. Book a consultation for a personalized quote.
