About

Dr. Ramkishen Narayanan is a urologic surgeon and researcher whose work centers on advancing surgical techniques and improving patient outcomes in robot-assisted urologic oncology. His primary research areas include surgical simulation, tissue engineering for surgical training, and postoperative recovery optimization following radical prostatectomy. Dr. Narayanan’s most impactful contribution is the development and validation of a novel, tissue-based simulator for robot-assisted radical prostatectomy (RARP), detailed in his 2014 paper (24 citations). This work created a realistic, sequential training model using porcine tissue, addressing a critical gap in surgical education by allowing surgeons to practice key procedural steps before operating on patients. He has also investigated the use of cryopreserved placental tissue allografts to accelerate time to continence after RARP (2021, 8 citations), demonstrating a commitment to enhancing functional recovery. Additionally, his research comparing open and laparoscopic approaches for upper pole kidney tumors (2012) contributes to the evidence base for nephron-sparing surgery. Through these efforts, Dr. Narayanan is shaping safer, more effective surgical practices in urology.
