Dr. Pierorazio is an assistant professor of urology and oncology at the Johns Hopkins University School of Medicine.

An expert in treating urinary-tract malignancies—including kidney, bladder, prostate, testis, adrenal, penile and urethral cancers—Dr. Pierorazio performs both open and minimally invasive surgeries. These include laparoscopic and robotic surgeries of the kidney, bladder, prostate, and retroperitoneal lymph node dissection for testicular cancer. 

He has a special interest in kidney cancer and performs such specialized procedures as partial nephrectomy for early-stage disease and high-risk surgeries for advanced urological cancers.  He is the Director of the Division of Testicular Cancer and works with a number of testicular cancer advocacy groups around the country.  He runs the testicular cancer "Go-Team" and coordinates the departments research efforts in testicular cancer. 

Dr. Pierorazio earned his medical degree from the Columbia University College of Physicians and Surgeons, where he also spent a year as a Doris Duke Charitable Foundation Clinical Research Fellow in urologic oncology. He completed a surgery internship and urology residency at The Johns Hopkins Hospital. He holds an undergraduate degree in physics from Georgetown University.

He leads the Delayed Intervention and Surveillance for Small Renal Masses Registry, a large study of patients with localized kidney tumors for which he received the National Comprehensive Cancer Network’s 2013 Young Investigator Award.

Dr. Pierorazio has earned many other professional honors and presented his research at meetings around the world. He also has authored scores of research articles and textbook chapters in the field of urologic oncology.
