Extracorporeal Shock Wave Lithotripsy (ESWL)

Extracorporeal Shock Wave Lithotripsy (ESWL) is one of the most common treatments for kidney stones. High-energy shock waves are directed at a kidney stone, causing it to break apart.

ESWL is one of the most commonly used methods for getting rid of kidney stones. With this procedure, a lithotripter sends shock waves from outside your body to reach the kidney stones. The repeated impact from the machine puts stress on the stone, causing it to eventually crumble into sand-like pieces that can be passed through urine.

UC Irvine Urology has long been recognized as a leader in the management of kidney stones.

What’s Next?

Guided by an X-ray or ultrasound, a urologist performs ESWL while the patient rests on a water-filled cushion. The shock waves are then passed through the body to break up the stones. A stent may be placed prior to ESWL to keep the ureter open and allow the broken pieces to pass through without causing any blockages.
