About

Yuya Ota is a urologic surgeon and researcher whose work is reshaping outcomes in robotic prostate and kidney surgery. His primary research focuses on optimizing functional recovery after robot-assisted radical prostatectomy (RARP), particularly through the Retzius-sparing (RS) approach. Ota’s most cited study (2020, 21 citations) identified key pelvic anatomical features—such as bladder neck position and membranous urethral length—that predict early urinary continence after RS-RARP, offering surgeons a roadmap to preserve quality of life. He further advanced the field by introducing the postoperative bladder neck-to-pubic symphysis ratio as a novel predictor for de novo overactive bladder (2023), enabling earlier identification of at-risk patients. In kidney cancer care, Ota pioneered the use of three-dimensional CT-based “resection process maps” (RPM) for robot-assisted partial nephrectomy (2024). This technique, validated in a propensity-matched cohort, allows surgeons to plan precise tumor excisions while maximizing nephron preservation. By merging detailed anatomical analysis with practical surgical planning, Ota’s work directly translates imaging into better continence and renal function outcomes, earning him recognition as a leader in precision urologic oncology.
