Dr. Hung-jui J. Tan

I specialize in the care of patients with urologic cancers – mainly prostate cancer, kidney cancer, bladder cancer and testicular cancer. A cancer diagnosis is one of the scariest things that can happen to someone. For many of our patients, they don’t necessarily feel different or look different, but they are scared to death. The most important thing you can get from Duke is real understanding of your particular case and what your options are. Knowledge is so reassuring and empowering for patients, especially those recently diagnosed with cancer. When you’re first diagnosed, you have to put your trust in a care team, and that’s hard to do if you don’t already know them. As the largest cancer center in North Carolina, Duke has great reputation and experience, which helps many patients chose Duke for their care. But we grow and develop our trust with patients because of who we are as people and how much expertise and care we bring to each case.

Prior to arriving at Duke, I was faculty at UT Southwestern where I had a dual appointment at the North Texas VA for 10 years. During this time, I was one of the highest volume robotic VA surgeons treating veterans with urologic cancer in addition to my clinic practice at UTSW. I joined the Urology department at Duke in 2024. At Duke, I have continued my focus on urologic oncology, specifically prostate, bladder and kidney cancer. I have a particular interest in prostate cancer. I was one of the earliest adopters of a novel surgical technique termed the Retzius Sparing Prostatectomy, which allows for the earlier return urinary control. I have further adopted a novel technique for the treatment of localized prostate cancer known as irreversible electroporation (IRE). This technique is a form of focal therapy for carefully selected patients. The advantages of IRE include less urinary and sexual side effects than conventional prostate cancer treatments. In addition, my clinical expertise includes advanced robotic reconstruction of the upper urinary tract. These procedures involve using segments of bowel or buccal grafts (inner lining of the cheek) to reconstruct damaged ureters.
