Other Treatments for Kidney Stones
Extracorporeal Shockwave Lithotripsy (ESWL)
- Does not pass after a reasonable period of time and causes constant pain
- Is too large to pass on its own
- Blocks the flow of urine
- Causes ongoing urinary tract infection
- Damages kidney tissue or causes constant bleeding
During this procedure you either sit in a water bath or lie on a cushion. The doctor uses a special machine to direct shock waves at the stone. The waves pass through the soft tissues of the body, but shatter the hard stone on contact, pulverizing it into smaller particles that can more easily be passed in the urine. A sedative or anesthesia is used to prevent pain during the procedure. ESWL takes anywhere from thirty minutes to two hours to complete, and you'll probably resume normal activities in one or two days. You may need to undergo several of these procedures before your stone is fragmented into small enough pieces to pass.
ESWL should not be done in patients with the following conditions:
Not all stones can be treated with ESWL. Your doctor will take into account the location, number, size, and composition of your kidney stone(s) in determining the best treatment.
