Ureteroscopy

Ureteroscopy (URS) is a form of minimally invasive surgery using a small telescope that is passed through the urethra and into the ureter to remove a stone. Often the stone requires fragmentation with a laser which then allows the smaller fragments to be removed with a grasping device. Only about 10-15% or urethral stones require surgical intervention. URS is approximately 95% successful in removing stones in the lower ureter and about 85-90% successful in treating and removing stones in the upper ureter and kidney.
