<prompt> Lithotripsy is the equipment used to crush the stonesHigh frequency CW US usedHigh frequency pulsed waveLow frequency continuous waveMedium range 2.5 MHz pulsed wave are used  <response>: .Cystoscopic litholapaxy Under GA, cystoscope is passed and the stone is visualized. It is fragmented by pneumatic, laser, electromagnetic waves or mechano-hydraulic lithotripsy. The bladder is flushed using an irrigator Freyers evacuator or irrigator or Elliks evacuator.in extracopreal shock wave lithotripsy ESWLPiezo-Ceramic or Electromagnetic shock waves are passed to the stone through water bath or water cushion which acts as a media. Shocks are produced at 2sec. 1000-4000 shocks are required for each stone. Dornier Lithotripter is used for fragmenting stones. Stone is located and observed through fluoroscope C-ARM or ultrasound. Shock waves are triggered to create compressive waves over the stone, to fragment it. These fragments are flushed out later. ref:SRB;s manual of surgery,ed 3,pg no 957
