This unit works with a rigid or semirigid endoscope to remove and destroy stones within the urinary tract. It uses CO2 gas to support the probe to break down stones that are normally hard to bear with. It does not need too many shocks in order to cut down stones. Also, the probe does not have to move much, thus keeping stones from sticking. It will not harm other tissues and can be transported anywhere thanks to a lack of foot pedals, cords and outside gas components.
