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.

Duke Ambulatory Surgery Center
I am focused on the surgical and medical management of kidney stones. I do a large volume of surgeries for kidney stones, however what gives me the most satisfaction in my practice is helping my patients prevent kidney stone recurrence. I work closely with my patients to determine the specific causes for their kidney stones. We review this information and then decide on a preventative plan, which often includes dietary changes and even medications. I find it extremely rewarding to help my patients prevent kidney stones, as many of them are surprised that it is possible to prevent them.
