Between May 1988 and December 1989, 369 patients were seen at our lithiasis unit. During that time the Unit had neither "percutaneous nephroscope" nor "ureterorenoscope". Twenty-three percent of the patients were not susceptible to therapy either due to spontaneous extrusion of their lithiasis or because it was not considered indicated. Of the remaining 77% (296 cases) 94.5% were referred for extracorporeal lithotrity with shock waves, of which 89.8 were monotherapy and 4.7% a combination with other strategies (medico-lithic, surgical, endoscopic extrusion). At the time of collecting the results, 216 patients had undergone some treatment. In those receiving shock waves, an EDAP piezoelectric lithotripter was used in 19.9% and a HM3-Dornier in 80% of the cases. Taking into consideration the overall resulted from last examination of each patient, 67% were free from lithiasic residues, 25% had residues under 4 mm, and 7.7% residues over 4 mm. 19.4% of the patients developed some kind of complication and 9 patients had to be admitted to hospital.
