About

Dr. Rangesh Kunnavakkam is a urological surgeon and researcher whose work bridges pediatric surgery, perioperative safety, and outcomes research. His key research areas include robotic-assisted urological surgery, surgical complications, and patient safety in minimally invasive procedures. Dr. Kunnavakkam made major contributions to understanding the safety profile of robotic surgery in children, leading a multi-institutional study on ninety-day perioperative complications in pediatric robotic urological surgery—a foundational work cited over 45 times that has informed clinical guidelines and surgical decision-making. He also conducted a landmark analysis of nearly one million prostatectomy and hysterectomy cases from the National Inpatient Sample, demonstrating that corneal abrasion risk was not increased with robotic-assisted prostatectomy but was nearly fourfold higher during laparoscopic hysterectomy compared to open surgery. This work, cited 22 times, highlights his focus on rare but impactful perioperative events. Dr. Kunnavakkam’s research is notable for its large-scale, data-driven approach to improving surgical outcomes, making him a respected voice in the fields of pediatric urology and surgical safety.
