Abstract

Compared with previous electromagnetic lithotripters, such as the EMSE 220 F and the 220 F-xp, the new EMSE 220 F-XXP produces a kind of shock wave with modified parameters. The Focal Positive Pressure (P+) reaches a lower value od 90.4 MPa; in the same way the Focal Negative Pressure (P-) reaches the –8.0 MPa. The width of the shock wave increases to 412 ns and the Effective Energy value on the 12 mm plane (Eeff) reaches the 110 mJ. 587 pazients and 612 renal stones units were treated with the DLS 220 F-XXP. The stone location was: 153 pelvic stones patients and 157 stone units (P); 57 upper calyx patients and 59 stone units (UC); 109 patients with medial calyx stones and 117 stone units (MC); 268 patients with inferior calyx stones and 279 stone units (IC). The stones size ranged between 5–60 mm in the P group, between 4–30 mm in the UC group; between 4–15 mm in the MC group and between 4–40 mm in the IC group.
