ESWL is used to remove a stone that:
During this procedure, the doctor uses a special machine to direct shock waves at the stone. The waves pass through the soft tissues of the body. They shatter the hard stone on contact and pulverize it into smaller particles that can be passed in the urine more easily. A sedative or anesthesia is used to prevent pain during the procedure. ESWL takes anywhere from 45-60 minutes to complete. You will probably resume normal activities in 1-2 days. You may need to have several of these procedures before your stone is small enough to pass.
Some factors that may increase the risk of complications include:
