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.

I specialize in treating people with genitourinary (GU) cancers, such as bladder, prostate, testicular and kidney cancer. I don’t treat other types of cancer across the breadth of tumors like some oncologists in the community may, such as blood cancer, breast cancer or lung cancer. My focus has allowed me to gain deep expertise in GU cancers and to stay abreast of the newest treatment advances, clinical research and so on for those specific GU cancers. As a medical oncologist, I meet patients at one of the scariest moments of their lives. I try to help educate them to make a decision about their disease and its process, and what their treatment options may be, so we can come to a shared decision about what might be the best option. The teaching aspect really strikes home for me. Both of my parents are teachers. The root word for “doctor” in Latin means “to teach.” So that is something I’m both naturally called to do and enjoy doing.

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.

Every day, my goal is to take the best surgical care of my patients' kidney or prostate cancer by offering the most up-to-date minimally invasive surgical treatments, while making sure that their experiences and outcomes at Duke Health are top-notch! As we look at the scans together and discuss biopsy results, it is important to me that I spend all of the time that my patients and their families need to clearly understand their diagnosis as well as all treatment options, so that we can make joint decisions about next steps and their treatment plan. Many of my patients are referred from all over the country to seek highly specialized urology care, including nonsurgical focal cryotherapy for prostate cancer, robotic surgery for prostate cancer, or robotic surgical removal of their kidney tumor called a partial nephrectomy, among other treatments, with our multidisciplinary, collaborative team. I always reassure and share my positive outlook with my patients as we navigate the health system together. My patients know that, as their physician, I will be their champion and advise them and guide them through their treatment. We are in this together.

I am a urologic oncologist who specializes in the diagnosis and surgical treatment of tumors of the urinary tract in men and women. I employ minimally invasive techniques as much as possible in order to maximize quality of life and recovery from treatment. Examples include robotic surgical removal of the prostate, kidney tumors, and bladder with complete robotic reconstruction. I am passionate about researching tests and treatments that will help my patients achieve cure of their cancers. I believe this starts with understanding risk factors for cancer to guide screening and early detection of tumors. I enjoy listening to my patients and understanding their goals of care. I believe that cancer care is a team sport and the patient is the captain. I collaborate with other specialists to make a comprehensive treatment plan including but not limited to surgery. In my free time, I enjoy exploring the outdoors with my wife and two daughters. Dr. Abern is rated as a Distinguished provider by MediFind in the treatment of Renal Cell Carcinoma (RCC).
