Office-based kidney stone management with new ultrasound technologies

Despite the growing incidence of urinary stones, the fundamental interventions for urinary stones have remained the same for several decades. However, technical innovations in ultrasound have enabled new strategies for stone management. Our team aims to employ these methods to establish a new paradigm to treat stones in an office or clinic rather than a surgical suite. Technologies include new imaging methods to detect and characterize stones, burst wave lithotripsy to fragment stones using focused ultrasound rather than shock waves, and ultrasonic propulsion to promote clearance of fragments, all using a single ultrasound platform. This presentation will describe the principles and development of these technologies, as well as the fruitful partnerships between teams of basic scientists, engineers, physicians, and industry that have enabled rapid development of these concepts to successful clinical trials.
