How is extracorporeal shock wave lithotripsy (ESWL)?
Extracorporeal shock-wave lithotripsy (ESWL) was introduced into clinical practice in the early 1980s. Experience has shown it to be a safe, effective and non-invasive treatment; the majority of upper-urinary-tract stones can be managed in this way. Success depends not only on stone size but also on location, chemical composition and anatomical factors. Stone size: Renal stones < 20 mm in diameter should be considered first-line for ESWL. Stone location: Pelvic stones fragment most readily; upper- and mid-calyceal stones respond better than lower-pole stones. Stone composition: Struvite and calcium-oxalate-dihydrate stones break easily; uric-acid stones can be treated with ESWL combined with... Learn more
