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.

I find the reconstructive aspect of urologic surgery the most exciting and challenging from a strategic and surgical perspective. Reconstructive urology provides an opportunity to help improve and to restore function as well as aesthetics for the patient who has endured injury, cancer, previous surgical complications, or congenital conditions. The uniqueness of each case poses a tactical and a surgical challenge, requiring a highly individualized and carefully planned and executed surgical approach to address the problem and underlying anatomical and medical cause. Within the emerging subspecialty of reconstructive urology, I focus on complex urethral stricture disease utilizing anastomotic and substitution urethroplasty; management of upper urinary tract obstruction; urinary fistula repair; prosthetic urology including penile implants for erectile dysfunction, as well as artificial urinary sphincters and minimally invasive slings for male stress urinary incontinence; penile reconstruction for Peyronie’s disease; and a comprehensive approach to male sexual health and male wellness.

I have a special interest in the use of surgical lasers for the treatment of benign prostatic hyperplasia (BPH) and kidney stones. I am specialized in endourology, which focuses on using scopes to perform surgery, oftentimes without the need for incisions. I perform HoLEP for BPH and find this to be an especially rewarding part of my practice. I look forward to helping patients understand their condition, and I provide patients with evidence-based treatment options that best fit with their goals and beliefs. In my spare time, I enjoy spending time with my wife and children, cooking, hiking, BBQ, outdoor concerts, and reading.

While I treat many urologic conditions, I have advanced training in minimally-invasive robotic treatments of common urologic issues, such as prostate enlargement, prostate cancer, kidney cancer, and blockages of the ureters. I recognize the sensitive nature of many urologic conditions and always treat patients the way I want to be treated myself. I practice with an emphasis on providing the highest quality care while also providing the shortest recovery and best functional outcomes possible. For example, during prostate removal, my techniques are focused on quality nerve and muscle preservation to limit risks of surgery, such as erectile dysfunction or urinary incontinence. I find that this approach addresses many quality-of-life concerns. Dr. Morgan is rated as an Experienced provider by MediFind in the treatment of Obstructive Uropathy.
