Minimally Invasive and Endourology

The Brady Urological Institute of the Johns Hopkins Medical Institutions offers a highly specialized and comprehensive fellowship training program in Endourology and Minimally Invasive Urological Surgery. This program is unique in that fellows are exposed to aspects of minimally invasive urology.  

The fellowship is a two-year program with integrated clinical and research components, leading to Endourological Society certification. The program is based at two campuses of the Johns Hopkins Medical Institutions, the Johns Hopkins Hospital and Johns Hopkins Bayview Medical Center, both located in Baltimore, Maryland. The fellow is appointed as a faculty member with title of Instructor in Urology with full hospital admitting and operative privileges, allowing the fellow to gain surgical autonomy and develop experience in resident education. 

The fellowship is structured to train individuals interested in pursuing a career in academia.
