Jonathan Warner, M.D.

After Jonathan Warner, M.D., finished college, he spent a year volunteering with a soup kitchen in Baltimore. It was during this experience that he saw firsthand how health issues dramatically impact people’s lives as they get older. 
“Seeing how many issues these people had to deal with got me interested in medicine, especially in how I could help older patients,” Warner said.
When Warner got his medical degree at the University of Utah School of Medicine, he started looking into which fields of medicine would best match his interest in working with patients struggling with health problems later in life.
I explored cardiology and internal medicine, but urologic problems really affect older people a lot,” he said. “It’s also a hands-on field, with a good mix of clinical practice and a variety of surgical approaches, from open surgery to endoscopic and robotic procedures.”
After his residency at the Mayo Clinic, a fellowship in reconstructive urology at the Detroit Medical Center helped him hone the skills that have, today, made him one of the country’s top reconstructive urologists.
"Robotic surgery was a heavy focus during my residency, and I've been able to take those robotic skills and apply them to the reconstructive realm," Warner explained.
We’re using surgery to restore a patient's function back to normal, which is quite a bit different than a lot of surgeries that focus on removing problems. It’s really a fine art form.”
In 2015, Warner came to City of Hope along with his wife, surgical oncologist Susanne Gray Warner. As an assistant professor for the Department of Surgery’s Division of Urology and Urologic Oncology, Warner focuses primarily on men’s health issues, seeing patients at City of Hope’s Glendora practice and its Pasadena location, which specializes in urology and urologic cancer treatments.
“For the average patient, these satellite locations offer high-quality care, closer to home,” he said. “A big advantage for me is I get to stay involved with the local communities, and I’m able to practice the type of urology I’m interested in practicing.”

Quality Of Life

One important area of focus for Warner is his passion for improving quality of life for prostate cancer survivors, and he’s renowned for his use of advanced techniques in urologic reconstruction. He’s one of only a handful of surgeons in the country who can restore normal urinary function in patients with urethral stricture, a narrowing of the channel through which urine empties from the bladder that is commonly damaged after prostate radiation and sometimes after prostate surgery. He also helps manage erectile dysfunction in older men and those suffering after prostate cancer treatment.
Warner is also highly regarded for his unique approach to the management of benign prostate problems. Over the last few years, he has been quietly but skillfully propagating a prostate surgery technique called bipolar enucleation, which was only used in Europe until recently.
“Probably the biggest thing I do that few others offer is this specialized approach to enlarged prostate surgery,” Warner said. The operation removes close to 100 percent of the obstructing tissue. “We know it has better long-term outcomes, there’s less blood loss and our patients can go home the same day of the operation, no matter the size of the prostate, which is pretty unique to City of Hope."
