What is URS Surgery?
URS (Ureteroscopy) is a minimally invasive endoscopic procedure used to diagnose and treat stones located in the ureter or kidney.
A thin, flexible scope is inserted through the urinary tract without any incisions, allowing direct visualization and treatment of stones.
URS is often combined with laser lithotripsy to break stones into small fragments that can be removed or naturally passed.
It is one of the safest and most effective treatments for ureteral and small-to-medium kidney stones.
Why is URS Surgery Needed?
URS is recommended for:
-
Stones stuck in the ureter (upper, mid, or lower ureter)
-
Stones causing severe pain or urinary blockage
-
Stones not passing spontaneously
-
Patients who cannot undergo ESWL
-
Stones resistant to medications or previous treatments
-
Urinary tract infections caused by obstructive stones
It provides quick symptom relief and immediate stone removal.
