The fragmentation of gallstones by extracorporeal shock waves is other of the nonsurgical threapeutic variants to be taken into account in this entity. 1 957 patients referred from all over the country with the diagnosis of biliary lithiasis were studied in a specialized office established to this end at “Hermanos Ameijeiras” Clinical and Surgical Hospital. 626 (32 %) were selected, 479 (76.6 %) females and 147 (23.4 %) males, and the criteria of the Group of Munich were initially followed. 125 patients (20.0 %) were over 60. 672 were not included due to large lithiasic component (50.4 %); 276 due to gallblader excluded in oral cholecistography (20,8 %); and 212 to insufficient gallblader dumping (16,0 %). Arterial hypertension (67,0 %), diabetes melitus (45,0 %) and ischemic heart disease (28.0 %) were the most frequent associated diseases among the selected individuals. The single calculi (71.7 %) of up to 20 mm of diameter (65.7 %), radiotransparent (83 %) and with densities under 50 Houndsfield units (60.5 %) predominated
