Overview
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.

Clinical Research
Clinical research consists of overseeing clinical studies of patients undergoing new treatments and therapies, and publishing articles in peer reviewed medical journals. Providers who actively participate in clinical research are generally at the forefront of the fields and aware of the most up-to-date advances in treatments for their patients.
Duke Cancer Center
I have a passion for caring for men with prostate cancer and helping them and their families make the best treatment decisions. I am nationally and internationally recognized as a prostate cancer expert and have performed more than 2,000 radical prostatectomies both at Duke and formerly at Walter Reed Army Medical Center. I specialize in the nerve-sparing technique of surgery affording the best chance for sexual recovery. I have more experience with this small incisional open hands-on nerve-sparing operation than any surgeon in the Southeastern United States and am among the 10 most experienced surgeons using this technique in the United States. In addition to surgery, I have extensive experience managing men who have an elevated PSA and perform a gentle prostate biopsy using very liberal doses of local anesthesia. Our team also offers management of men who elect active surveillance for their early stage prostate cancer and are sensitive to men's needs regarding management of temporary urinary and sexual dysfunction related to prostate cancer treatments. We have a very experienced nursing team and a very experienced physician assistant who greatly assists in comprehensive and compassionate care. Dr. Moul is rated as a Distinguished provider by MediFind in Prostatectomy. His top areas of expertise are Prostate Cancer, Familial Prostate Cancer, Enlarged Prostate (BPH), Prostatectomy, and Orchiectomy.
Duke Cancer Center
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 Prostatectomy.

Duke Cancer Center Genitourinary (GU) Clinic
I am a urologic oncologist who is specifically trained in the surgical management of cancer. As a result of my fellowship and training, I feel very comfortable handling complex cancer cases. My patients are my favorite part of my job. I feel it’s incredibly important to make a connection with the patient and listen to them. It’s an amazing privilege to be able to take care of another human being and an honor to operate on someone. Surgery is a unique specialty, it’s a direct invasion of a person’s body and they are putting their trust in you. Duke is an amazing place. I was immediately attracted to Duke’s commitment of excellence when I first came here for training in the 1980s. Outside of my job, I enjoy fishing, golfing and spending time with my wife.
