Core Faculty

Jonathan Harper, MD

Jonathan Harper, MD

Dr. Harper joined the University of Washington (UW) Urology Department after completion of an Endourology and Minimally Invasive Surgery Fellowship at UCLA Medical Center in 2009.  At UWMC, he is the primary provider of complex kidney stone management and he holds a strong interest in new technology and ultrasound-related research focused on treatment of urinary stone disease.  After joining UW, an immediate collaboration with the Center for Industrial and Medical Ultrasound (CIMU) was developed and he has served as research co-mentor with Michael Bailey, PhD to four urology residents. Innovative research technologies have been created under this collaboration including the development of ultrasonic propulsion of kidney stones, burst-wave lithotripsy (a new form of lithotripsy) and the development of a focused ultrasound instrument for clamping and cauterizing tissue that could potentially aid in kidney surgery.  He is the clinical PI of the first human clinical trial of ultrasonic propulsion of kidney stones that was completed this past year and presented the results at the plenary session of the AUA annual meeting and engineering in urology session of the endourological society annual meeting.  He is an integral member of an extended research team that has been awarded renewal of a Program Project Grant (PPG) with Indiana University, entitled Innovative Strategies for improving outcomes in nephrolithiasis. The goal of the current project is to build on a successful innovation with ultrasonic propulsion of kidney stones by redefining the technology that could greatly improve patient outcomes in an impactful manner.  Dr. Harper was PI of a recently completed randomized placebo controlled trial investigating a novel use of Belladonna and Opium suppository for the preemptive treatment of ureteral stent pain following stone kidney stone surgery.  This was presented at the 2015 Western Section AUA Annual meeting and manuscript is in progress.  He has the expertise, interest, motivation, and clinical volume to contribute in all aspects in leading a urinary stone disease clinical center. Currently, Dr. Harper is a Professor and the Chief of Endourology and Minimally Invasive Surgery in the Department of Urology, University of Washington School of Medicine

Mathew Sorensen, MD, MS

Mathew Sorensen, MD, MSDr. Sorensen is an Assistant Professor in the Department of Urology with a specialty interest advanced laparoscopic surgery, endourology, and the medical and surgical management of kidney stones.  He completed his surgical internship and urology residency at UW.  During his dedicated research year he began a collaboration with the Applied Physics Laboratory and completed a rigorous Masters degree in Epidemiology through the University of Washington School of Public Health.  After residency, he went on to complete a fellowship in Laparoscopy and Endourology at the University of California, San Francisco.  Since returning to UW as faculty in 2011, he has continued to collaborate with the Applied Physics Laboratory and the Center for Industrial and Medical Ultrasound group and actively participates in several studies attempting to improve stone sizing and detection using ultrasound.  In 2012 he was named the Director of the Comprehensive Metabolic Stone Clinic at the Puget Sound VA Hospital.  He also has a particular interest in education and in 2014 became the Urology Residency Program Director.  His research interests have focused on epidemiologic, outcomes, and health services-related projects as well as basic science and translational ultrasound research.  Dr. Sorensen has been a part of the effort to detect and reposition stones since the ideas inception. He also used ultrasound to study the effect of respiration on shock wave lithotripsy in humans.  Dr. Sorensen has participated in the Program Project Grant (PPG) on Shock wave lithotripsy.
