The Fate of Residual Fragments after Extracorporeal Shock Wave Lithotripsy

Abstract
The principle of extracorporeal shock wave lithotripsy (SWL)—fragmentation of urinary calculi within the urinary tract—contradicts the longheld tenet of classic stone surgery, which claims that complete removal was the principal goal of stone therapy. Thus, evaluation of the success of SWL therapy is closely associated with the problem of residual stones.
