In Memoriam

Demetrius H. Bagley Jr., MD, FACS

Dr. Demetrius H. Bagley Jr., passed away on, January 17, 2022. Demetrius was the Nathan Lewis Hatfield Professor of Urology and Radiology at the Sidney Kimmel Medical College of Thomas Jefferson University in Philadelphia, PA, and was part of our department since 1983. He is known internationally for his contributions to the field of endourology, particularly ureteroscopy and its diagnostic and therapeutic applications in diseases of the upper urinary tract. In 2010, he was the recipient of the Karl Storz Lifetime Achievement Award, and in 2014 he was awarded the American Urological Association Lifetime Achievement Award for visionary leadership and educational contributions in ureteroscopy and minimally invasive surgical techniques for the upper urinary tract. He was a member of the American Association of Genitourinary Surgeons.

Prior to his time at Jefferson, Dr. Bagley attended medical school at Johns Hopkins University, and urology residency at Yale University before fellowship at the NCI. His interest in endourology began in 1979 as an assistant professor at the University of Chicago. Together with Drs. Ed Lyon and Jeffrey Huffman, he pushed the boundaries of ureteroscopy, defining the limitations of the available instruments, and relentlessly working to improve and refine them.

Dr. Bagley’s passion for education matched his innovative contributions. In addition to the publication of more than 400 original papers and books, he has trained over 60 residents and endourology fellows. Many have risen in academia throughout the United States, and internationally in Egypt, the United Kingdom, Zimbabwe, Singapore, Israel and

Japan. Fully appreciating the importance of a care team, he was a strong supporter of multidisciplinary education, frequently including nurses and medical assistants in academic projects. Additionally, Dr. Bagley has presented many courses to educate practicing urologists. Spanning nearly three decades, these include AUA courses, international hands-on, live demonstration and lecture courses and visiting professorships and invited lectureships in over 35 countries. Video presentations of his techniques and new instruments lead to widespread adoption of his methods.

His vision and tireless pursuit of excellence lit the path for the contemporary practice of semirigid and flexible ureteroscopy. Words cannot express our appreciation for his contributions and leadership in the field of endourology. Demetrius will be sorely missed and truly is irreplaceable.

The Jefferson community extends sympathy to his wife Jackie, son Jacques, and daughter-inlaw Kathy on their loss. An online memorial to Dr. Bagley including many photos and comments from trainees and colleagues from around the world can be found at www.kudoboard.com/boards/cBvbKrsG
