About

Kyohei Watanabe is a urologic surgeon and researcher whose work focuses on improving functional and quality-of-life outcomes after robot-assisted surgery for prostate and kidney cancers. His research centers on two key areas: predicting and managing post-prostatectomy complications like de novo overactive bladder (OAB) and urinary incontinence, and optimizing surgical outcomes for complex renal tumors. In a 2022 study (11 citations), he identified predictive factors for developing OAB after robot-assisted radical prostatectomy, providing clinicians with tools to better counsel and manage patients. His prospective evaluation of health-related quality of life after robot-assisted partial nephrectomy (8 citations) was among the first to quantify the real-world impact of nephron-sparing surgery on patient well-being. Watanabe also demonstrated that tumor complexity significantly affects perioperative outcomes (8 citations), helping surgeons stratify risk before complex partial nephrectomies. His work using postoperative MRI to measure bladder neck angle (5 citations) offers a novel anatomical predictor of continence recovery. Through these contributions, Watanabe has advanced the field of robotic urologic oncology by bridging surgical technique with patient-centered outcomes, earning recognition as a leader in functional recovery after minimally invasive cancer surgery.
