About
Dr. Kunihiko Yoshioka is a pioneering Japanese urologic surgeon whose research has fundamentally shaped the adoption and refinement of robot-assisted surgery for prostate and bladder cancers. His work centers on optimizing perioperative outcomes, surgical safety, and functional recovery—particularly urinary continence—after radical prostatectomy. Dr. Yoshioka was among the first in Japan to prospectively compare robot-assisted radical cystectomy (RARC) with open surgery (52 citations), and his landmark analysis of the learning curve across 200 initial robot-assisted radical prostatectomies (RARP) (36 citations) provided crucial benchmarks for surgeons worldwide. He developed a risk stratification model for biochemical recurrence after RARP using a cohort of 784 Japanese patients (31 citations), and his investigations into surgical techniques—such as double-layered posterior rhabdosphincter reconstruction (29 citations) and lateral bladder neck preservation (21 citations)—have directly improved early continence recovery. Dr. Yoshioka also led a multi-institutional study using a national database to demonstrate the impact of surgeon and hospital volume on RARP safety (18 citations). His cumulative work, with papers cited over 240 times, has established evidence-based standards for robotic urologic oncology in Japan.
