About
Yoichi Arai is a leading urological surgeon and researcher whose work centers on improving outcomes for prostate cancer patients, particularly through the refinement of surgical techniques and perioperative care. His major contributions lie in understanding and predicting postoperative urinary incontinence, a critical quality-of-life issue. In a highly cited 2022 study (11 citations), Arai demonstrated that minimal residual membranous urethral length (mRUL) measured on preoperative MRI is a robust predictor of poor continence recovery after both robot-assisted and open radical prostatectomy, providing surgeons with a valuable tool for patient counseling and surgical planning. He also led an influential international survey (2020, 15 citations) that characterized global practice variation in thromboprophylaxis for urological surgery, highlighting the lack of standardization and informing future guidelines. Additionally, his work on the controversies surrounding radical prostatectomy in elderly men (2014, 6 citations) has helped shape nuanced, age-appropriate treatment decisions. With over 30 years of clinical and academic experience, Arai’s research directly bridges imaging biomarkers and surgical outcomes, making him a key figure in evidence-based urology.
