Abstract

Extracorporeal shock-wave lithotripsy (ESWL) is a cost-effective approach to the management of symptomatic urolithiasis. Many patients with asymptomatic renal stones wish to have prophyactic destruction of these stones by ESWL. However, there are no good data on the prognosis of asymptomatic urolithiasis nor are there any clinical trial data comparing the alternative strategies of early prophylactic ESWL to later ESWL as indicated by symptoms. The prognosis of asymptomatic urolithiasis is described in this study.
