Dornier MedTech invented extracorporeal shockwave lithotripsy, (ESWL), more than 25 years ago for the disintegration of kidney stones, which is today the gold standard for urinary stone treatment.
 
Extracorporeal Shock Wave Lithotripsy (ESWL) is the most frequently used treatment method of kidney stones.  Prior to treatment, the stone is located by the use of X-ray or ultrasound.  During the procedure, a light anesthetic may be given to help reduce any discomfort.  The treatment delivers high-energy shock waves to a precise location in the body to crush the stones into small fragments, at the same time avoiding damage to surrounding soft tissue.  The stone fragments then pass naturally through urination.  The procedure takes approximately 30 to 60 minutes, and can be performed in a hospital or out-patient center.
