A noninvasive tool to reposition kidney stones could have significant impact in the management of stone disease. Our research group has developed a noninvasive transcutaneous ultrasound device. A review and update of the current status of this technology is provided. DISCUSSION OF TECHNOLOGY: Stone propulsion is achieved 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 effectiveness for the relocation of calyceal stones have been demonstrated in the porcine model. ROLE IN ENDOUROLOGY: This technology may have applications in repositioning stones as an adjunct to lithotripsy, facilitating clearance of residual fragments after lithotripsy, expelling de novo stones, and potentially repositioning obstructing stones. Human trials are in preparation.
一种无创的肾结石定位工具可能会对结石病的治疗产生重大影响。我们的研究小组开发了一种无创经皮超声设备。本文提供了对该技术现状的回顾和更新。技术讨论：通过短时间的聚焦超声脉冲实现结石推进。最初的系统由一个八元件环形阵列换能器、计算机和独立的超声成像仪组成。在当前的一代中，成像和治疗由一个超声系统和一个商业探头完成。这一代系统允许实时超声成像、靶向和推进。在猪模型中已经证明了该技术用于重新定位肾盏结石的安全性和有效性。在腔内泌尿外科中的作用：该技术可能适用于碎石术的辅助定位，促进碎石术后残余碎片的清除，排出新形成的结石，并可能重新定位梗阻性结石。人体试验正在准备中。
