In order to establish the appropriate criteria of ESWL to Japanese patients, we reevaluated the efficacy of ESWL according to various factors of the stone. Respect to the stone number, the group of 2 or less in number showed satisfactory stone-free rate, although the stone size did not affect the stone-free rate, Ultrasonical types of the stones were the most sensitive factor for predicting freedom of stones; the stone-free rate was estimated at 100% and 60% in type I a, b and type I c plus type IIa, respectively. Calcification of the stones was not an excluding criteria, since the estimated stone-free rate of calcified stones with a thin rim or laminated rim reached to 83% after 20 months.<BR>We, therefore, proposed a new criteria for the patient selection: 1) history of biliary pain,2) one or two stones in number,3) types I or IIa of ultrasonographic classification,4) non-calcified stones or calcified stones with a thin rim or a laminated rim, and 5) gallbladder visualization on oral cholecystogram. When this criteria was adopted for the selection of patients, about 29% of the outpatient with gallbladder stones was indicated for ESWL and the cumulative stone-free rate was estimated at 91%.
