Our providers and philosophy
The Department of Urology’s Urologic Oncology Program provides comprehensive care for patients with urologic cancers. We value the multi-disciplinary approach to cancer treatment, collaborating closely with our Radiation Oncology and Medical Oncology colleagues, and we offer a wide range of leading-edge surgical cancer treatments involving advanced open, laparoscopic and robotic approaches. For referred patients or those seeking a second opinion, we are committed to prompt evaluation and coordinated, compassionate cancer care. We provide streamlined access both for patients and referring physicians.
Each of our urologic oncologists bring with them specialty fellowship training, with 100% of their clinical practices dedicated to the evaluation and treatment of patients suffering from cancer of the prostate, bladder, kidney, and testis. Department of Urology surgeons are renowned for their expertise in treating complex cases that include high risk cancer, post-chemotherapy treatment, and salvage surgery following radiation therapy. In addition to expertise in traditional open surgery, they also utilize their advanced training in the use of minimally-invasive and robotic surgical techniques. Our robust volumes in open, minimally invasive, and robotic surgical cases assure the experience necessary for optimal postoperative outcomes.

An expert in the minimally-invasive surgical treatment of urologic cancers, he is a high-volume surgeon utilizing robotic surgical techniques for the treatment of prostate, bladder, kidney and testicular cancer, though his primary clinical interest lies in the treatment of prostate cancer.
Dr. Jen-Jane Liu, M.D. completed her medical training and urology residency at Stanford University, followed by fellowship training in urologic oncology at John Hopkins Hospital. Dr. Liu performs both open and minimally invasive surgery for the spectrum of urologic malignancies, including prostate, bladder, kidney, and testicular tumors. Her particular research interests lie in clinical outcomes and practice patterns of urologic oncology surgery and new imaging technologies for urologic cancers.
Dr. Sudhir Isharwal, M.D. provides care for patients with cancers of genital and urinary tract. His clinical and research focus include bladder cancer, kidney cancer, prostate cancer, and testis cancer. He performs advanced minimally invasive surgeries including robotic assisted laparoscopic surgeries as well as open surgeries.
