Abstract:
The predictive parameters for effect of ESWL have been considered by stone size, locations, chemical composition and hydronephrosis, etc. However, there are several questions that ""how much shock wave will be needed for completely removal of stone and how can we predict effect of ESWL in some patients with renal stone?"" Therefore we have measured bone mineral density (BMD) and stone mineral density(SMD) as a predictive parameter for the effect of ESWL in patient with renal stone. As results, The storages of ESWL for complete response were correlated with the sizes (p<0.01, r=0.740) and the stone mineral density (p<0.01, r=0.852). Stone mineral density was variable even same size stones and the requirement of shock wave for complete response in 1.00-1.99 cm sized stones was correlated with SMD. (p<0.01, r=0.795 ). From this study, the measurement of SMD may be the objective and predictive parameter for effect of ESWL in patient with renal stone.
