About
Kazuyoshi Shigehara is a urological surgeon and researcher whose work centers on robot-assisted radical prostatectomy (RARP), urinary continence mechanisms, and minimally invasive treatments for urological cancers. His most significant contributions lie in elucidating why Retzius-sparing RARP (RS-RARP) yields superior postoperative urinary continence compared to conventional approaches — a question he has pursued rigorously through dynamic MRI studies involving hundreds of patients, earning 17 and 10 citations respectively for two landmark papers on this topic. His research has provided clinicians with objective, imaging-based evidence to guide surgical decision-making and improve patient quality of life following prostatectomy. Beyond continence research, Shigehara has made meaningful contributions to surgical oncology, comparing robot-assisted partial nephrectomy with cryoablation in elderly renal cancer patients and investigating biochemical recurrence patterns following RARP. His prospective randomized trial on inguinal hernia prevention post-RARP (10 citations) reflects a commitment to reducing surgical complications. He has also contributed to national clinical standards, co-authoring Japan's 2023 guidelines on perioperative infection prevention in urology. With a cumulative body of work spanning surgical technique refinement, functional outcomes, and evidence-based guidelines, Shigehara represents a clinician-researcher meaningfully advancing the field of robotic urology.
