Item First In-Human Burst Wave Lithotripsy for Kidney Stone Comminution: Initial Two Case Studies(Mary Ann Liebert, Inc., 2021) Harper, Jonathan D.; Metzler, Ian; Hall, Michael Kennedy; Chen, Tony T.; Maxwell, Adam D.; Cunitz, Bryan W.; Dunmire, Barbrina; Thiel, Jeff; Williams, James C., Jr.; Bailey, Michael R.; Sorensen, Mathew D.; Anatomy, Cell Biology and Physiology, School of MedicinePurpose: To test the effectiveness (Participant A) and tolerability (Participant B) of urinary stone comminution in the first-in-human trial of a new technology, burst-wave lithotripsy (BWL). Materials and Methods: An investigational BWL and ultrasonic propulsion system was used to target a 7-mm kidney stone in the operating room before ureteroscopy (Participant A). The same system was used to target a 7.5 mm ureterovesical junction stone in clinic without anesthesia (Participant B). Results: For Participant A, a ureteroscope inserted after 9 minutes of BWL observed fragmentation of the stone to <2 mm fragments. Participant B tolerated the procedure without pain from BWL, required no anesthesia, and passed the stone on day 15. Conclusions: The first-in-human tests of BWL pulses were successful in that a renal stone was comminuted in <10 minutes, and BWL was also tolerated by an awake subject for a distal ureteral stone.
