There were differences in the number of sessions related to the size of the lithiasis, 1.3 session in the group of lithiasis smaller than 1 cm and 2.01 sessions in the group bigger than 1 cm. The stones that required less number of sessions were located in the ureter and upper calyx. 71.2% of the patients were stone free after one treatment. Conclusions: Siemens Lithostar Modularis has the adventages of a great confort of the patient during the procedure, better image because of a very good cuality of the fluoroscopy and the main point is a great comminution of the stone doing very easy the elimination of the fragments achieving a stone free rate of more than 90 % in our experience, decreasing the need of auxiliary manoeuvres and the leng of the treatment.
