ESWL (Extracorporeal Shock Wave Lithotripsy) is a non-invasive procedure used to break up stones in the urinary system (kidneys and ureters), pancreas, and bile ducts using shock waves. These shock waves are targeted at the stones with the aid of X-rays or ultrasound.
Here's a breakdown of the procedure:
-
Non-Invasive Nature: ESWL is performed externally, meaning no surgical incision is required.
-
Targeting Stones: Using imaging techniques like X-rays or ultrasound, the medical team precisely locates the stone(s).
-
Generating Shock Waves: A machine called a lithotripter generates high-energy shock waves.
-
Fragmentation: These shock waves are focused on the stone, causing it to fragment into smaller pieces.
-
Natural Passage: The smaller fragments are then able to pass out of the body naturally through the urine. Stones in the kidneys and ureter often pass on their own after ESWL.
ESWL offers a less invasive alternative to surgical stone removal.
