Initial EDAP LT-01 lithotripsy group experience in the United States

Area of Science:

• Urology
• Medical Devices
• Nephrology

Background:

• Extracorporeal shock wave lithotripsy (ESWL) is a common treatment for kidney and biliary stones.
• Previous lithotriptors often required anesthesia and involved radiation exposure.
• Advancements in lithotripsy technology aim to improve safety and patient comfort.

Purpose of the Study:

• To present the initial United States cooperative experience with the second-generation piezoelectric extracorporeal shock wave lithotriptor, the EDAP LT-01.
• To evaluate the safety, efficacy, and feasibility of using this device with ultrasonic guidance for stone treatment.

Main Methods:

• The study involved using the EDAP LT-01 lithotriptor, which utilizes piezoelectric technology and ultrasonic guidance.
• The procedure was conducted on an outpatient basis without the need for anesthesia or electrocardiographic monitoring.
• Data on stone fragmentation, destruction rates, and complications were collected over 595 treatments targeting 633 stones.

Main Results:

• The EDAP LT-01 demonstrated a high degree of safety with a paucity of complications, including no renal losses or deaths.
• Fragmentation rates were approximately 86%, with an overall destruction rate of 63.4%.
• Ultrasound localization and monitoring were found to be easily learned and effective, with only 3 cases of steinstrasse observed.

Conclusions:

• The EDAP LT-01 represents a significant advancement in extracorporeal shock wave lithotripsy, offering a radiation-free, anesthesia-free, and safe outpatient procedure.
• The device is effective for treating both renal and biliary stones, with results comparable to earlier lithotriptors.
• The use of ultrasound guidance is practical and contributes to the overall safety and success of the treatment.
