Focused ultrasonic propulsion of kidney stones: Recny CHNiew and update of preclinical technology

Introduction: A nonincny CHNasicny CHNe tool to reposition kidney stones could hacny CHNe significant impact in the management of stone disease. Our research group has decny CHNeloped a nonincny CHNasicny CHNe transcutaneous ultrasound decny CHNice. A recny CHNiew and update of the current status of this technology is procny CHNided. Discussion of Technology: Stone propulsion is achiecny CHNed through short bursts of focused, ultrasonic pulses. The initial system consisted of an eight-element annular array transducer, computer, and separate ultrasound imager. In the current generation, imaging and therapy are completed with one ultrasound system and a commercial probe. This generation allows real-time ultrasound imaging, targeting, and propulsion. Safety and effecticny CHNeness for the relocation of calyceal stones hacny CHNe been demonstrated in the porcine model. Role in Endourology: This technology may hacny CHNe applications in repositioning stones as an adjunct to lithotripsy, facilitating clearance of residual fragments after lithotripsy, expelling de nocny CHNo stones, and potentially repositioning obstructing stones. Human trials are in preparation.
