Abstract

Once an adequate percutaneous tract is created, the next step is to clear the stone. The fragmentation and extraction strategies should be tailored according to stone (hardness, location, size, and burden) and instrument (chosen size of the Amplatz sheath, diameter of the working channel of the endoscope in use) factors. Such strategies are similar in both prone and supine position, in spite of the fact that the slightly downward inclination of the Amplatz sheath in the supine position favors fragments’ spontaneous evacuation. Various tips and tricks, like the variety of laser settings with their different effects or the vacuum-cleaner effect, are described.
