URSL
Procedure Overview
URSL (Uretero-Renoscopy with Laser Lithotripsy) uses a rigid or semi-rigid scope passed through the natural urinary passage to reach and treat stones in the mid or lower ureter, without any external incision.
Who Needs It
URSL is well suited to stones located in the mid or lower ureter, and is often a same-day or short-stay option for appropriately sized stones.
Preparation
Standard preparation includes imaging confirmation of the stone's location, blood tests, and a period of fasting before anesthesia.
Step-by-Step Procedure
Anesthesia
General or spinal anesthesia is given.
15 minScope Insertion
A rigid or semi-rigid ureteroscope is passed through the urethra and bladder to the ureter.
10 minLaser Fragmentation
A laser fiber breaks the stone into small fragments or dust.
20–30 minFragment Retrieval
Fragments are removed with a small basket where needed.
10 minStent Placement (if needed)
A temporary DJ stent may be placed to support healing, removed a couple of weeks later.

Frequently Asked Questions
A kidney stone (renal calculus) is a hard mineral deposit that forms in the kidney from concentrated urine. Stones vary in size and type, and small ones may cause no symptoms at all. When should I consult Dr. Raju R?
Bladder stones form directly in the bladder, usually because it isn't emptying fully, unlike kidney stones which form in the kidney. When should I consult Dr. Raju R?
Classic stone pain starts suddenly in the flank or back and radiates to the groin, often in waves, with nausea and sometimes blood in the urine. When should I consult Dr. Raju R?
Stones form when urine is too concentrated with calcium, oxalate, or uric acid. Low water intake, salty or high-protein diets, obesity, and family history all raise the risk. When should I consult Dr. Raju R?
Diagnosis uses a urine test, blood test, ultrasound, and usually a CT KUB scan, the most accurate way to see stone size and location. When should I consult Dr. Raju R?
