  • Extra Corporeal Shock Wave Lithotripsy (ESWL) or Simply Lithotripsy
  • It is a device for fragmentation of stone; and is used in management of renal , ureteric and bladder stones.
  • mechanism of action :  It generates shock waves, which are reflected ( with the help of reflector) to the stone .These shock waves cause the fragmentation of the stones.
  • Imaging of stones: It is done by high frequency 9" C - Arm Image Intensifier.

        (for middle/ lower ureteric calculi, URS ( Ureterorenoscopy) is the preferred mode of treatment)

  • Bladder stones (calculi): ESWL can be done; but the preferred mode of treatment is Cystoscopic Lithotripsy due to its cost effectiveness.

  • Preparation for ESWL:
  • Correction of UTI (Urinary Tract Infection), if any by, antibiotics, This is confirmed by urine culture and sensitivity.
  • Blood Investigations such as CBC (with platelets), Sr. Creatinine,
