Kimihiko Masui

About

Dr. Kimihiko Masui is a leading urologic surgeon whose research centers on advancing minimally invasive kidney cancer surgery, particularly through robot-assisted partial nephrectomy (RAPN). His major contributions lie in three interconnected areas: comparative effectiveness of surgical approaches, intraoperative force sensing, and 3D navigation. His landmark propensity-matched study (12 citations) demonstrated that RAPN achieves superior perioperative outcomes over open partial nephrectomy for small renal tumors, helping to establish robotic surgery as a standard of care. In a pioneering 2024 work (9 citations), Masui developed a deep learning model that estimates manipulation forces from laparoscopic images, addressing the critical challenge of absent haptics in robotic surgery—a breakthrough that could enhance surgical precision and training. He has also advanced 3D kidney modeling from CT scans to improve surgical planning for partial nephrectomy. His analysis of trifecta outcomes (2 citations) for T1b tumors provides valuable benchmarks for surgical success. Masui’s work bridges surgical technique, artificial intelligence, and imaging innovation, with growing citation impact that underscores his influence on the future of urologic oncology.
