Dr. Allaf is an Associate Professor of Urology and Biomedical Engineering at the Brady Urological Institute and Director of Minimally Invasive and Robotic 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.

His main clinical interest includes the treatment of kidney tumors and prostate cancer in the least morbid way possible. He specializes in the management of kidney tumors via laparoscopic (total and partial kidney removal) and percutaneous (non-surgical) approaches. He also has an interest in the careful and active observation of select small kidney tumors. His other areas of focus include performing nerve sparing radical prostatectomy in all its forms (open, laparoscopic, and robotic) as well as reconstructive laparoscopy (pyeloplasty) and laparoscopic management of testicular cancer (retroperitoneal lymph node dissection).

His research endeavors involve investigating approaches to minimize the morbidity of urologic surgery and the development of ways to decrease injury to the neurovascular bundles and hasten erection recovery following radical prostatectomy. Dr. Allaf has been the recipient of numerous academic awards, including placing first in the 2005 American Urological Association clinical and laboratory research annual essay contests. He has written and published numerous research articles, textbook chapters, patents and video presentations in the field of Laparoscopic and Robotic Urologic Surgery. Trinity J. Bivalacqua, M.D, Ph.D

Christian Pavlovich, M.D
  Office: 410 550-0013
  Appointments: 410-550-7008

Dr. Pavlovich came to Johns Hopkins after completing a Urologic Oncology fellowship at the National Cancer Institute. His practice is dedicated primarily to the treatment of prostate, kidney and bladder cancer, as well as to the treatment of benign prostatic diseases. He is experienced in open, laparoscopic, and robotic minimally invasive surgery for the management of urologic tumors, including nerve-sparing laparoscopic and robot- assisted radical prostatectomy, laparoscopic and robotic nephrectomy and partial nephrectomy, and robotic radical cystectomy.

A particular expertise of his is the robotic extraperitoneal (or retroperitoneal) approach to the prostate and kidney for patients with prostate or kidney cancer. This approach, which avoids entry into the abdominal cavity, is ideally suited for patients that have had prior abdominal or inguinal operations (e.g. hernia repairs, appendectomy, colectomy) or who have inflammatory conditions (e.g. Crohn’s disease, ulcerative colitis, diverticulitis) that might make an abdominal robotic approach more hazardous.

Dr. Pavlovich is accepting new patients and is delighted to offer second opinions regarding the treatment of any urologic malignancy. Phillip M. Pierorazio, M.D.
