Lithotripsy is the equipment used to crush the stones
Correct Answer: High frequency (CW) US used
Description: .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 (Freyer's evacuator or irrigator or Ellik's evacuator).in extracopreal shock wave lithotripsy (ESWL)Piezo-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 2/sec. 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
