About

Motoki Yamagishi is a urologic surgeon and researcher whose work centers on improving outcomes in robot-assisted radical prostatectomy (RARP) for prostate cancer. His primary research focus is the preoperative prediction of adverse pathological features, particularly seminal vesicle invasion (pT3b), a critical factor that can unexpectedly upstage a patient’s disease and alter treatment planning. In his most cited study, Yamagishi analyzed a cohort of RARP patients to identify preoperative predictive factors for pT3b, demonstrating that clinical variables such as biopsy Gleason score and prostate-specific antigen levels can help surgeons anticipate this high-risk finding. This work has direct implications for surgical decision-making, enabling more accurate patient counseling and potentially reducing the need for adjuvant therapies. While his citation count is currently modest, his research addresses a pressing clinical challenge in urologic oncology: the gap between preoperative risk stratification and final pathology. Yamagishi’s contributions are particularly valuable for surgeons seeking to refine their technique and improve oncologic outcomes in the era of robotic surgery.
