Rapid Communication: Endoscopic Lithotripsy with a New Device Combining Ultrasound and Lithoclast

BACKGROUND AND PURPOSE: Endoscopic lithotripsy is still the method of choice for a number of stones, especially large stones. Various disintegration techniques exist. We investigated the combination of two of these techniques: ultrasound and pneumatic lithotripsy. PATIENTS AND METHODS: Fourteen consecutive patients with renal and one patient with bladder stones were treated with this new device. Ultrasound and pneumatic lithotripsy could be used independently or simultaneously. RESULTS: Disintegration and stone removal was fast. The use of forceps or other instruments could generally be avoided. No complications attributable to the lithotripsy device were observed. CONCLUSION: The combined ultrasound/pneumatic lithotripsy device is safe and highly effective. It reduces treatment time and enhances surgeon's comfort.
