The first generation (G1) ESWL uses positive and negative electrode rod to discharge in water to have spark and generate shock wave. The shock wave is then deflected by oval shape steel bowl to focus at a fixed focal point, and when the focal point is focused on the kidney stone; the focused shockwave applies energy on the stone and break it. After thousands times of hitting, the stone will be pulverized. This is called Electrohydraulic Shock Wave Generator.

The second generation (G2) ESWL is of dry treatment. Patient does not need to immerse in water tank, but with water cushion fit to skin and the water blade transmit the focused shockwave into body and penetrates through skin to attain the purpose of breaking stone. In this manner, the inconvenience of pre-treatment preparation is reduced greatly, and ESWL techniques become widely applied on treatment of urine duct calculus. Unfortunately, the result of treatment (Stone Clearing Rate) is no better than G1 ESWL. In order to reduce the X-ray radiation dosage, G2 ESWL offers also ultrasound localization model, an option to X-ray localization. G2 machines are placed inside surgery room mostly and patient needs general anesthesia or local anesthesia.
