ESWL medical abbreviation-Extracorporeal shock wave lithotripsy used to treatment of the Kidney stone less than 2 cm in size. The stone sizes reduce into small fragments using this procedure.
It produces uses sound waves (also called shock waves) to break these stones into small pieces. It focuses on shock waves that pass through the tissue and fluids and stones.
Used in kidneys and gall bladder stones rarely.
The recommended waves for fragments- 1500
The bigger stones break into small fragments using a continuous flow of shock waves on a focused point. The fragments excrete in urine through the ureter and bladder.
Investigation 
Ultrasound -USG
Intravenous Pyelography
Retrograde Utereopyleography
Fluoroscopy
CT, etc
