Dr. Phillip Pierorazio is an Associate Professor of Urology and Oncology in the Brady Urological Institute at Johns Hopkins University.  Dr. Pierorazio is originally from New York, received his undergraduate degree from Georgetown University in Washington, DC and his medical degree from Columbia University, College of Physicians & Surgeons in New York City where he completed a Doris Duke Clinical Research Fellowship in Urologic Oncology.

Dr. Pierorazio has expertise in all malignancies of the urinary tract and performs both open and minimally-invasive surgeries including 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, including partial nephrectomy for early stage disease and high-risk surgeries for patients with advanced cancers. 

His research interests parallel his clinical practice, including high-risk prostate and urothelial cancer. He has a special interest in testicular and kidney cancer (renal cell carcinoma), studying both advanced and early-stage disease.

He runs the Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) Registry - one of the largest active surveillance registries for patients with small kidney tumors. He sits on both the AUA and National Comprehensive Cancer Network  (NCCN) Guidelines Committees for Kidney Cancer.

He is also the Director of the Division of Testicular Cancer, a member of the NCCN Guidelines committee, 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 is the recipient of a number of academic awards including the American Urologic Association Essay Contest, NCCN Young Investigator Award, and has presented his research at a number of national and international meetings. He has written and published numerous research articles, textbook chapters, and video presentations in the field Urologic Oncology. more

Research Summary

Dr. Pierorazio’s primary research interest is high-risk urologic malignancies, with a focus on both early-stage and advanced renal- cell carcinoma.

He leads the Delayed Intervention and Surveillance for Small Renal Masses Registry—one of the largest studies of its kind—which follows patients who have small, localized kidney tumors (cT1a, ≤ 4 cm) and choose active surveillance or immediate surgery.
