Ashutosh K. Tewari (born in Kanpur, India) is a board certified American urologist, oncologist, and clinical researcher at Weill Cornell Medical College of Cornell University in New York City where he directs the Institute of Prostate Cancer and Robotic Surgery.[1] Tewari holds the Ronald P. Lynch endowed Chair of Urologic Oncology and is the hospital's Director of Robotic Prostatectomy, treating patients with prostate, urinary bladder and other urological cancers.[2] He is one of world's leading urological surgeons, and has been involved with over 3500 robotically assisted procedures using the da Vinci Surgical System.[3][4] Since joining Weill Cornell Medical College he has performed over 2500 robotic procedures. Academically, he is recognized as a world renowned expert on urologic oncology with over 250 peer reviewed published papers to his credit; he is on such lists as America's Top Doctors, New York Magazine's Best Doctors, and Who's Who in the World.[5]


Robotic prostatectomy

With the introduction of the da Vinci Surgical System, the advent of robotic surgery using a laparoscopic approach has significantly changed the way prostate cancer surgery and prostatectomy procedures in general are performed as compared to the traditional 'open' methodology.[6][7] Much of Tewari's research projects serve to promote robotic surgery as opposed to open procedures. For example, Tewari has shown that the operating field has become more visible to the surgeon, unobscured by the copious amounts of blood encountered in traditional surgery and is thus able to view the urological structures under three-dimensional, enlarged magnification.[8] Patients reap even greater benefits.[9][10] Due to the minimally invasive nature of the procedure, they experience minimized pain, minimized blood loss, less scarring and fewer complications. Post-surgery recovery is accelerated and patients experience quicker return to urinary continence and sexual function.[11][12] Some of Tewari's current research is focused on comparing the benefits of robot-assisted surgery with traditional open prostatic surgery.


Tewari is the Director of the Lefrak Institute of Robotic Surgery, Director of Prostate cancer, as well as the Director of Robotic Prostatectomy and Prostate Cancer-Urologic Oncology Outcomes at the Brady Urology Foundation of Weill Medical College.[13] He is a tenured Professor of Urology at Weill and, additionally, a Professor at the Department of Public Health and Outcomes.[14][15] In addition, Tewari directs a fellowship program in Robotic Prostatectomy and Prostate Cancer Outcomes that has conducted research comparing robotic surgery outcomes versus those of laparoscopic and open surgeries.[16] Tewari is an Attending physician at the New York Presbyterian Hospital.[17]


Receiving his medical education from Ganesh Shankar Vidyarthi Memorial Medical College (GSVM) in Uttar Pradesh, India, Tewari graduated with honors in 1984 with 17 gold academic medals to credit.[18] He received his training in urology from Sanjay Gandhi Post Graduate Institute of Medical Sciences (SGPGIMS) in India under the mentorship of Professor Mahendra Bhandari and completed the McH and DNB program in 1991.[19]


Tewari has trained in the U.S. under Dr. Mani Menon, a pioneer of robotic prostatectomy and continues to collaborate with him in refining treatment outcomes. Tewari completed his urology residency at the Vattikuti Urology Institute (VUI) of the Henry Ford Hospital in Detroit, Michigan in 2004. He received his urologic oncology research training at the University of California, San Francisco in 1994, the University of Florida in 1998, and VUI in 2004.


Tewari's research interests revolve around the diagnosis and treatment of patients with urological cancers, with a focus on prostate cancer. His research ranges from the study of patient outcomes, robotic techniques, molecular markers for cancer aggressiveness, racial disparity in cancer biology, quality of life studies, strategies to improve nerve sparing and sexual function recovery, and anatomic studies to facilitate continence preservation to the development of next generation robotic techniques.[20] He has received several federal and non-federal research funding grants for his research on prostate cancer, totaling several million dollars in grant capital. He is one of the only urologists in the world to receive an NIH R01 Grant.[21][22] Additionally, he is among the first surgeons to use real time tissue imaging during surgery to minimize nerve damage in the patient and was the first surgeon in the world to use the catheter-less Prostate Surgery. The catheter-less surgery minimizes postoperative pain after prostatectomy[23]
