Dr. Abaza’s Experience in Robotic Urology

A native of Toledo, Ohio, Dr. Ronney Abaza earned his undergraduate degree at the University of Michigan. He then attended Northwestern University Medical School before returning to his hometown for residency training in urology at the University of Toledo Medical Center. He began his practice in Toledo and specialized in robotic surgery to expand access to advanced robotic procedures for patients in the area. He was the first in Northwest Ohio to perform robotic kidney cancer surgery, robotic ureteral surgery, robotic urinary diversion and robotic bladder cancer surgery.

The practice Dr. Abaza founded continues to lead the Toledo community in robotic surgery.

Dr. Abaza served as the founder and medical director of St. Vincent Hospital’s Laparoscopy, Simulation & Robotics Training Center. As a faculty member at the University of Toledo College of Medicine, Dr. Abaza performed research in surgical techniques, performed kidney transplantation and instructed medical students and residents.

Through cutting-edge research protocols, Dr. Abaza continues to develop new techniques in robotic urologic surgery and tracks the results of every robotic surgery he performs. This research allows him to analyze his patient results and continuously improve his outcomes by refining techniques and creating new ways to perform robotic surgery for complex conditions. Many state, regional and national urologic societies have honored Dr. Abaza with awards to recognize him for his pioneering leadership in the field of robotic research.

Speaker and Instructor

As one of the world’s foremost authorities on robotic urology, Dr. Abaza has been sought after as a speaker at national and international society meetings, and he has given more than 150 presentations on robotic prostate, kidney and bladder surgery. His work in robotic surgery has been published extensively in medical journals, including articles on several new robotic procedures and techniques performed for the first time ever by Dr. Abaza. Two such techniques were featured on the covers of major urology journals in 2011, including the Journal of Endourology and European Urology.

Dr. Abaza is also passionate about teaching robotic surgical techniques and has been instructing surgeons in multiple fields for several years. He organized and directed the National Urology Resident Preceptorship in Robotic Urologic Surgery, the first-of-its-kind program dedicated to robotic surgery and held annually for residents from around the country over five years. He has been director of a robotic urologic surgery fellowship program since 2010, offering one year of additional training in robotic surgery for graduates of urology residency programs. Dr. Abaza is editor of a textbook that is the only published textbook dedicated to robotic kidney surgery.

Dr. Abaza frequently serves as faculty for educational courses both in the U.S. and internationally and as a panelist, moderator or course director for programs at the annual meetings of various national and international medical societies, including the American College of Surgeons and American Urological Association. In 2012, he performed live robotic surgical procedures for all three of the major conferences for robotic surgeons, including the American Urological Association (AUA) Annual Meeting, the World Congress of Endourology and the European Robotic Urology Symposium of the European Association of Urology. He has also performed live robotic surgery for the International Robotic Urology Symposium, the North American Robotic Urology Symposium and the Ohio Urologic Society Annual Meeting, among other medical conferences, and will perform live surgery for the Society of Robotic Surgery Annual Meeting in 2019. 

OhioHealth Dublin Methodist Hospital

In 2013, Dr. Abaza moved his practice to OhioHealth Dublin Methodist Hospital, so as to refocus all of his professional efforts on his first love, providing excellent patient care. While shifting his academic efforts with his move to Dublin Methodist, Dr. Abaza continues to track his outcomes for every patient to ensure the highest quality of care and to share his experience with other surgeons through reasearch and publications. He also continues to teach by continuing his fellowship and by serving as faculty for educational courses for practicing surgeons to learn or refine their robotic surgical techniques. He also continues to welcome surgeons from around the country and the world to Dublin Methodist to observe him performing robotic surgery.

Top Reasons to Have Your Robotic Surgery With Dr. Abaza

Because of his extensive experience and dedication to robotic surgery, Dr. Abaza is able to offer robotic surgery to many patients who were previously not considered candidates, such as obese patients, patients with previous abdominal and prostate surgery and patients with high-risk or complex cancers. This also includes patients who have had their prostate cancer return after radiation.

Highest Possible Outcomes

Dr. Abaza has taken advantage of the consistent and highest-quality outcomes he provides his patients to create clinical care pathways that allow avoidance of narcotic pain medications and the shortest hospital stays ever reported for several types of robotic procedures.

Through research and by applying that research in practice, he is able to provide his patients with an unmatched level of care.

The Most Experienced Robotic Surgeon in Ohio

Dr. Ronney Abaza has been performing surgery using the da Vinci Surgical System since 2006. In 2008, he dedicated his practice solely to robotic surgery for conditions of the prostate, kidney, bladder and adrenals. With more than 5,000 robotic surgeries performed, Dr. Abaza is the most experienced robotic surgeon in Ohio across all surgical fields. His annual number of robotic procedures places him among the top 5 surgeons in the world.

Dr. Abaza is a leader and innovator in the field of robotic urology. He has pioneered several complex robotic procedures that had never been previously performed. This allows patients with even the most complicated conditions, once thought impossible to treat robotically, to benefit from minimally-invasive robotic surgery performed by Dr. Abaza. His unique and unparalleled skill and experience allows Dr. Abaza to perform robotic procedures with the best possible outcomes for patients.

First in the World

Dr. Abaza was the first in the world to perform the following procedures:

  • Robotic Nephrectomy for Kidney Cancer with Caval Thrombus
  • Robotic Partial Nephrectomy for Kidney Cancer with Vein Thrombus
  • Robotic Adrenalectomy for Adrenal Carcinoma
  • Robotic Kidney Autotransplantation
  • Robotic Ureteral Repair after Cystectomy for Bladder Cancer

Dr. Abaza believes strongly that surgeons who are creating the future of robotic surgery through research and innovation can provide their patients of today the best possible operation. This is not only because they can use their discoveries and advancements to benefit their patients before other surgeons have adopted these techniques, but also because a dedication to innovation reflects a passion for giving every patient — those of today and those of the future — the best possible care. Dr. Abaza has shared his research, innovations and passion for robotic surgery in many different publications.
