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 and prostate.

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.

Dr. Pierorazio’s primary research interest is high-risk urologic malignancies, with a focus on renal-cell carcinoma, a type of kidney 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.
