Bioeffects of shock wave lithotripsy

Abstract

Injudicious use of shock wave lithotripsy can lead to unwanted effects. The acute bioeffects of shock waves such as renal hemorrhage can be reduced by a number of measures, which include pretreatment with shockwaves, slowing the fi ring rate, and reducing the total number of shock waves delivered and the power of the shock. Improving the coupling between the patient and machine also improves effectiveness and reduces harm. Long-term effects include renal scarring and new-onset hypertension. This chapter explores the mechanisms by which these bioeffects are produced.
