is used to remove a stone that:
Does not pass after a reasonable period of time and causes constant painIs too large to pass on its ownBlocks the flow of urineCauses ongoing urinary tract infectionDamages kidney tissue or causes constant bleeding
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: Bleeding disorder or taking medicine to reduce blood clottingObesitySkeletal deformities
If you are pregnant, ESWL cannot be done.
