About
Dr. Atsushi Otsuka is a pioneering urologic surgeon whose work centers on advancing robotic surgery for renal and adrenal diseases. His major contributions lie in the rigorous clinical evaluation of novel surgical platforms, particularly the hinotori surgical robot system. Dr. Otsuka has led some of the first prospective assessments of hinotori for partial nephrectomy, radical nephrectomy, adrenalectomy, and nephroureterectomy, collectively amassing over 200 citations since 2023. His landmark studies, including a propensity score-matched analysis comparing hinotori to the da Vinci system, demonstrate that the new platform achieves comparable perioperative outcomes, establishing its feasibility and safety. Beyond platform validation, Dr. Otsuka has refined surgical technique through investigations into early unclamping strategies, the impact of tumor anatomy on outcomes, and three-dimensional volumetry of perinephric fat to predict operative complexity. His work on the learning curve for robotic partial nephrectomy provides essential guidance for surgeons adopting these technologies. By systematically evaluating both established and emerging robotic systems, Dr. Otsuka is shaping the future of minimally invasive urologic oncology.
