Patients And Methods:
We describe the outcome of the treatment of 1.000 consecutive patients treated since may 2000 to december 2003 with Siemens Lithostar Modularis to evaluate the efficacy of this new lithotripter
Results:
60.5% male and 39.5% female's patients were treated. Average age of 53.5 years old. 44.1% of the urinary stones were located on the right side and 55.9% on the left. The mean size of the stones was 1.22 +/- 0.74 cm with 59% lesser than 1 cm, 27.6% between 1 and 2 cm and 13.4% bigger than 2 cm. Mean number of sessions required were 1.6. 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.
