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 " howmuch shock wave will be needed for completely removal of
stone
and
how can we predict effect of ESWL in somopatients 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 fo 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 ㎠ 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.
