Electrohydraulic and extracorporeal shock-wave lithotripsy.

The literal meaning of lithotripsy is the "act of breaking stones." There are two forms of lithotripsy available for use in veterinary medicine: electrohydraulic shock-wave lithotripsy (EHL) and extracorporeal shock-wave lithotripsy (ESWL). With EHL, a shock-wave is generated immediately adjacent to a urolith within the urinary bladder. In dogs, nephroliths or ureteroliths can be successfully treated with ESWL. With ESWL, the shock-waves are generated outside the body and directed toward the urolith.
