Laser Lithotripsy: Ureteroscopy (URS) for Kidney and Ureter Stones

Ureteroscopy (URS) is a procedure used to treat stones in the kidney and ureter. It involves passing a very small telescope, called a ureteroscope, through the bladder, up the ureter, and into the kidney. This allows the urologist to directly visualize and treat the stone without making any incisions.

Types of Ureteroscopes

  • Rigid telescopes are used to treat stones located in the lower part of the ureter, near the bladder.
  • Flexible telescopes are used for stones located in the upper ureter or the kidney.

How Does the Procedure Work?

General anesthesia is administered to ensure you are comfortable during the procedure. Once the urologist has visualized the stone using the ureteroscope, smaller stones may be removed with a small basket-like device.

If the stone is too large to remove in one piece, it can be broken into smaller pieces using a laser or other stone-breaking tools.

Stent Placement

After the stone(s) are removed, a temporary stent may be placed in the ureter. A stent is a small, rigid plastic tube that helps keep the ureter open, allowing urine to drain from the kidney into the bladder. Unlike a catheter or drainage tube, the stent remains entirely inside the body and does not require an external urine collection bag.

Recovery

  • Most patients can go home the same day as the URS procedure and typically return to normal activities within two to three days.
  • If a stent is placed, it will usually be removed in four to 10 days. In some cases, a string may be attached to the end of the stent, allowing the patient to remove it at home.

Important Considerations

It is crucial to have the stent removed as directed by your urologist. Leaving the stent in for too long can lead to complications, including infections or loss of kidney function.
