Dr. Allaf is Professor of Urology, Oncology, and Biomedical Engineering at the Brady Urological Institute and Director of Minimally Invasive and Robotic Urological Surgery at the Johns Hopkins Hospital.  He joined the staff after receiving his undergraduate and medical degrees from the Johns Hopkins University and completing his residency and advanced training in Urology at Johns Hopkins, as well. 

As a urologic oncologist, his main clinical focus includes the treatment of kidney tumors and prostate cancer.  While expert in both open and minimally invasive surgery, he specializes in ROBOTIC approaches to these diseases and is amongst the busiest robotic surgeons in the world.  The following is a list of robotic procedures he performs on a regular basis:

    1. Nerve-Sparing Radical Prostatectomy
    2. Partial and Radical Nephrectomy
    3. Pyeloplasty
    4. Adrenalectomy
    5. Retroperitoneal Lymph Node Dissection (for testicular cancer patients)

Dr. Allaf also runs a research laboratory aimed at decreasing the morbidity associated with the treatment of urologic cancers.  He oversees a large registry of patients who have small kidney tumors and elect for careful and active observation.  Additionally, given his background as a biomedical engineer, he is a leader in developing future technological advancements in the field of robotic and minimally invasive surgery.  An example of this is the use of real-time elastography imaging during robotic prostatectomy to regain tactile feedback during this delicate procedure.

Dr. Allaf has been the recipient of numerous academic awards and has been invited nationally and internationally to demonstrate robotic surgery and lecture on robotic prostatectomy and kidney surgery.  He has written and published numerous research articles, textbook chapters, patents and video presentations in the field of Laparoscopic and Robotic Urologic Surgery.
