Bone demineralization, dehydration, and stasis put astronauts at an increased risk of forming kidney stones in space. The incidence of kidney stones and the potential for a mission-critical event are expected to rise as expeditions become longer and immediate transport to Earth becomes more problematic. At the University of Washington, we are developing an ultrasound-based stone management system to detect stones with S-mode ™ ultrasound imaging, break stones with burst wave lithotripsy (BWL ™

This review discusses the development and current state of these technologies, as well as integration on the flexible ultrasound system sponsored by NASA and the National The US FDA approved a feasibility study to assess whether stones could be repositioned in 15 adult human subjects [41] . There were no restrictions on stone size or position. The study Simon et al.
