[First clinical experience with extracorporeal lithotriptor EDAP LT.02]

A preliminary study of the EDAP LT.02 extracorporeal lithotriptor is presented. The apparatus includes a double isocentric detection system (ultrasonographic and radiological), facilitating the in situ treatment of ureteric stones. Seventy patients with a total of 89 urinary stones were treated by primary extracorporeal lithotripsy (ECL) with no preliminary selection. 69 stones (77.5%) were located in the kidney and 20 stones (22.5%) were situated in the ureter. Anaesthesia was only required in 2 cases. The patients received an average of 1.2 lithotripsy sessions. Out of the 70 patients treated, there were 46 (66%) complete successes, 12 (17%) partial successes and 12 (17%) failures [corrected].
