Makoto Sumitomo

About

Dr. Makoto Sumitomo is a leading urologic surgeon and researcher whose work centers on advancing robot-assisted surgery for prostate and kidney cancers. His major contributions lie in defining and predicting optimal functional and oncologic outcomes—specifically through the study of "trifecta" and "pentafecta" endpoints. In a landmark 2023 study (24 citations), he demonstrated that nerve-sparing robot-assisted radical prostatectomy significantly improves pentafecta achievement (continence, potency, cancer control, margins, and complications) compared to non-nerve-sparing approaches. For renal tumors, his 2019 work (17 citations) identified key predictors for achieving trifecta outcomes in high-complexity partial nephrectomies. Dr. Sumitomo has also pioneered the use of artificial intelligence in urology, showing in 2023 (12 citations) that deep learning analysis of intraoperative video can strongly predict urinary continence recovery after prostatectomy—a breakthrough for personalized surgical planning. His comparative studies (16 citations) have validated the long-term functional superiority of robot-assisted over open partial nephrectomy in Japanese cohorts. With over 150 total citations, his research is shaping evidence-based, patient-tailored robotic surgery.
