First experience with the Lithoring in the management of urinary stones.
The Lithoring Multi-One is a lithotripter recently developed in Italy. Its main features are (1) spark gap generator with large ellipsoid, with tunable power for treatments with or without analgesia; (2) localization by fluoroscopy and ultrasounds without moving the patient; (3) isocentric variation of shock wave window, and (4) multifunctional table. It can treat both urinary and biliary stones. The first 50 patients were treated without anesthesia with an average of 1,700 shock waves at 19.2 kV. 37 patients had stones larger than 1 cm. 13 patients had ureteral stones. Two patients had complete staghorn stones. The disintegration rate was 97.9%, the overall stone-free rate at 3 months' follow-up was 83.3%, and the retreatment rate was 1.29 treatments for patients. No complication occurred.
