In vitro comparison of 4 ultrasound lithotripsy devices
1Department of Urology, University of Cologne, Germany.
Purpose:
Endoscopic lithotripsy is still the method of choice for a number of stones, especially large renal stones. 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.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
