A ‘Smart’ and rather modest looking stethoscope may pack a big (figurative) punch. When medication does not break up kidney stones, shock wave lithotripsy is often used, but it is difficult to tell when the fragmentation process is complete. This device monitors the pulses as they echo off the stone, and by changes in sound (‘tock’ vs. ‘tick’) can confirm that the stones are shattered (any reference to Mick’s Group is unintentional but unavoidable). In clinical trials it has reported an accuracy rate of 94.7%, far above any existing tech. The Smart Stethoscope delivers no radiation, and can also be used as an assessment tool for probable response to lithotripsy. Developed by Prof. Tim Leighton (left) at University of Southampton with Guy’s and St. Thomas’ Foundation Trust (GSTT) and UK-based tech firm Precision Acoustics Ltd. which will be developing a commercial version. “Smart stethoscope” keeps an ear on kidney stones (Gizmag) Research study in Proceedings of the Royal Society A.
