Ureteroscopy with Laser Lithotripsy
Ureteroscopy with laser lithotripsy is a treatment for removing small- to medium-sized kidney stones. A telescope (ureteroscope) is inserted through the urethra and advanced into the bladder and further into the ureter until the stone is encountered. A laser fiber at the tip of the scope is applied to stone, breaking it into small sand sized particles.
The fragments are then allowed to pass on their own or can be captured and gently removed with a basket through the scope. The surgeon may also opt to place a stent in the ureter to hold it open so that stone fragments can pass more easily.
Ureteroscopy tends to have a higher success rate than extracorporeal shock wave lithotripsy, although it is more invasive. Ureteroscopy is less invasive than percutaneous nephrolithotripsy as no incisions are necessary.
Ureteroscopy with laser lithotripsy takes less than an hour and generally ban be performed in an outpatient setting.
