Endoscopic lithotripsy with a new device combining ultrasound and lithoclast

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.

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.

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.

The combined ultrasound/pneumatic lithotripsy device is safe and highly effective. It reduces treatment time and enhances surgeon's comfort.
