Robotic-Assisted Surgery


OSU is the cornerstone of a Nationally-Recognized Multidisciplinary Robotics Program. Robotic Surgery at Ohio State has a long and illustrious history begining with the first robotic surgery in North America in 1999. Since then OSU has continued to blaze trails in the field of robotic surgery with OSU Urology at the forefront of this continually growing multidisciplinary program. OSU currently performs over 100 robotic surgeries per month, placing OSU among the top 5 hospitals in the nation for robotic surgical volume. Approximately half of these procedures are performed by OSU Urology.

A world leader in robotic prostatectomy, the OSU James Cancer Hospital and Solove Research Institute is one of the nation’s premier cancer centers for performing robotic prostatectomies. The internationally recognized robotic prostatectomy team has one of the world’s largest experience in robotic surgery. 

Robotic prostatectomy incorporates the latest advancements in robotic-assisted technology and allows a surgeon greater visualization, enhanced dexterity, precision and control.  Patients who undergo this surgery experience faster recovery times, less blood loss, less pain and shorter hospital stays. In fact, most patients go home within 24 hours of the surgery.

Following on the heels of the laparoscopic movement in surgery, robotic-assisted surgery has been applied to most every laparascopic urology procedure. At the Ohio State Department of Urology, the da Vinci system is used because of its steady three-dimensional vision and improved dexterity.

The Genitourinary Oncology Program at OSUCCC-James has a multidisciplinary approach, featuring prostate, bladder, kidney, testicular, male genital and adrenal expertise. It provides patients a myriad of cutting-edge treatment options. Focusing on individual care for our cancer patients, our treatment team includes specialists in medical oncology, radiation therapy and urologic surgery. Our bench to bedside approach means patients are consistently offered newer, safer and more effective treatments as they are developed.

Ohio State’s Center for Advanced Robotic Surgery is a high volume center for robotic prostatectomy for prostate cancer. This progressive, world-class program features unmatched expertise in this minimally-invasive procedure. State-of-the-art care at Ohio State’s Center for Advanced Robotic Surgery is provided by a talented team of urologists, Dr. Ahmad Shabsigh, Dr. David Sharp, Dr. Geoffrey Box and Dr. Megan Merrill. Drs. Shabsigh and Sharp are fellowship trained in Urologic Oncology at Memorial Sloan-Kettering Cancer Center in New York. Dr. Box completed his fellowship in Laparoscopy, Endourology, Image-Guided Therapy and Robotic-Assisted Laparoscopy at the University of California, Irvine.  Dr. Merrill did her fellowship training in Urologic Oncology at MD Anderson in Houston. Since 2008, they have brought their surgical expertise to this high volume center for robotic prostatectomy.

OSUCCC-James is also a high volume center for renal cell carcinoma. Over 250 partial and radical nephrectomies are done annually. More than 65% of these are partial nephrectomies. Ohio State’s Center for Advanced Robotic Surgery is a leading center for robotic kidney surgery. The center is well known for robotic partial nephrectomy and radical nephrectomy for advanced renal cell carcinoma requiring inferior vena cava (IVC) thrombectomy.

OSUCCC-James is a regional leader in bladder cancer cure. We have one of the few multimodal teams in the region. The center is active in molecular stratification and imaging research. OSUCCC is one of 14 centers studying robotic radical cystectomy on an NCI grant. Opportunities to expand robotic surgery for bladder cancer are wide open.

In parallel, our radiation oncologists provide precision treatment for several genitourinary cancers with IMRT and brachytherapy.

We are currently offering numerous clinical trials aimed at preventing and reducing the risk of prostate cancer and other genitourinary cancers, including the largest national prostate cancer prevention trial to date.

Ahmad Shabsigh, MD

Dr. Ahmad Shabsigh is an Assistant Professor of Urology at The Ohio State University.  He is a board certified urologist, subspecializing in urologic cancer.

After obtaining his medical degree from Aleppo University Medical School in Aleppo, Syria , Dr. Shabsigh, joined the molecular urology research team at Columbia University in New York.  He worked extensively on understanding the impact of androgen deprivation on angiogenesis and prostate cancer.  He then continued his medical training in the department of surgery and the department of urology at the Columbia-Presbyterian Medical Center in New York.  Focusing on urologic cancer he then joined the fellowship program at Memorial Sloan- Kettering Cancer Center in New York. He joined the faculty of the Department of Urology at The Ohio State University in 2008.
His clinical interests emphasize a balanced and multimodality approach for the treatment and cure of genitourinary malignancies, including testis, kidney, bladder, and prostate cancers, implementing minimally invasive laparoscopic and robotic techniques in addition to standard surgical approaches.

His research interests include the development of clinical systems to improve quality of care and patient reported outcomes.  In addition he has special interest in translational research bridging the gap between bench research and clinical practice.

David S. Sharp, MD

Dr. Sharp is an Assistant Professor of Clinical Urology. He obtained his medical degree at Baylor College of Medicine in Houston, Texas. He completed his residency training at Cleveland Clinic Foundation, Glickman Urological Institute in Cleveland, Ohio.
Dr. Sharp completed fellowship training in urologic oncology at Memorial Sloan-Kettering Cancer Center in New York, before joining OSU Medical Center in 2008 and bringing his expertise in open, laparoscopic and robotic urologic cancer surgery to the James.

His clinical interests are urologic oncology, renal oncology, minimally invasive and robotic surgery.

Geoffrey N. Box, MD

Dr. Geoffrey N. Box is an Assistant Professor of Clinical Urology at The Ohio State University.  He completed his residency training at The Ohio State University in 2006.  He then went to the University of California, Irvine where he completed a two-year fellowship in Laparoscopy, Endourology, Image-Guided Therapy and Robotic-Assisted Laparoscopy.  He joined the faculty of OSU in 2008.

He is currently the Director of Laparoscopic Urology Surgery and will be responsible for the development and oversight of educational and research programs in this area.  In addition, he, along with Dr Bodo Knudsen, will be in charge of the Minimally Invasive Urologic Surgery Fellowship.

His clinical interests include the minimally invasive treatment of genitourinary disease using laparoscopic and robotic techniques with a focus on kidney and prostate cancers.

His research interests include the development of new surgical techniques to reduce the invasiveness of surgery.  Along those lines, he has been among the pioneers in urologic NOTES (Natural Orifice Translumenal Endoscopic Surgery) and currently serves as the co-chairman of the Urology NOTES Working Group.
