Various disintegration techniques exist. Ultrasound is widely used because it is the only method that allows disintegration and active suction of stone debris at the same time. We evaluated 4 ultrasound lithotriptors in vitro. Materials and Methods: We used a newly developed experimental setup and compared 4 ultrasound devices, namely the 27085 K (Karl Storz Endoscopy, Tuttlingen, Germany), 2167.01 (Wolf, Knittlingen, Germany), USL 2000 (Circon Corp., Santa Barbara, California) and an ultrasound prototype lithotriptor (EMS, Nyon, Switzerland). Results: All ultrasound lithotriptors achieved stone disintegration, which depended on the pressure used to apply ultrasound. Newer devices with modified technology provided better disintegration. Conclusions: All ultrasound devices are effective for lithotripsy. Changes in the ultrasound setup and integration of modern technical knowledge into ultrasound devices increase efficacy.
