Ureteroscopy with laser is a minimally invasive procedure to remove kidney stones by using a thin scope called a ureteroscope and a laser to break the stones into small fragments that can be passed or removed, with a temporary ureteral stent sometimes placed to ensure proper drainage. Performed under general anesthesia, the laser lithotripsy uses heat to fragment the stone, with techniques like the holmium laser ensuring precise control and preventing damage to the ureteral wall.  

What It Treats 

• Kidney Stones: This procedure is primarily used to treat kidney stones that are lodged in the ureter (the tube connecting the kidney to the bladder) and cannot pass on their own.

• Stones in Any Location: Ureteroscopy can address stones in the kidney or any part of the ureter.

How It Works

• Anesthesia: The procedure is performed under general anesthesia, so you will be asleep. 

• Scope Insertion: A thin, flexible instrument called a ureteroscope is inserted through the urethra and guided into the ureter and kidney to locate the stone. 

• Laser Fragmentation: A laser fiber is passed through the scope and directed at the stone. The laser's energy breaks the stone into very small pieces, called dust or small fragments. 

• Stone Removal/Passage: The fragmented stone pieces can then either be removed in a small basket, or they are small enough to pass out of the body through the urine over time. 

• Stent Placement: A temporary, flexible tube called a ureteral stent is often placed in the ureter to help urine and stone fragments drain from the kidney and to prevent blockage after the procedure. 

What to Expect After

• Recovery: You can typically go home the same day. 

• Activity: Walking is encouraged to prevent blood clots, but you may need to avoid strenuous activities and heavy lifting for a few days. 

• Stent Discomfort: You may feel discomfort from the ureteral stent, including symptoms like increased frequency of urination or blood in your urine. 

• Follow-Up: You may receive a prescription for antibiotics to prevent infection and instructions on managing any discomfort from the stent.
