About

Kanae Koyama is a urologic surgeon and researcher whose work focuses on refining surgical techniques in robot-assisted procedures for kidney and prostate cancers. Her key research areas include nephrometry scoring to predict intraoperative complications and the role of extended lymph node dissection in high-risk prostate cancer management. Koyama’s most cited study, “A low RENAL Nephrometry Score can avoid the need for the intraoperative insertion of a ureteral catheter in robot-assisted partial nephrectomy” (2021, 15 citations), demonstrates that lower nephrometry scores can safely eliminate the need for ureteral catheter placement, reducing invasiveness and operative time. This finding has practical implications for streamlining partial nephrectomy protocols. In a separate study on very-high-risk prostate cancer (2021, 4 citations), she explored the efficacy of extended robot-assisted laparoscopic prostatectomy with extended pelvic lymph node dissection as a monotherapy, contributing to the debate on whether surgery alone can improve outcomes in this aggressive disease subset. Koyama’s work is notable for its direct clinical applicability, offering evidence that can help surgeons tailor intraoperative decisions and potentially reduce patient morbidity. Her research continues to inform best practices in robotic urologic oncology.
