About

Chikao Aoyagi is a leading urologic surgeon and researcher whose work centers on preserving genitourinary function after radical prostatectomy, particularly in the era of robotic surgery. His major contributions lie in developing and refining nerve-sparing techniques that protect the cavernous nerves critical for erectile function and lower urinary tract health. Aoyagi’s 2021 paper, “Comprehensive approach for preserving cavernous nerves and erectile function after radical prostatectomy in the era of robotic surgery,” has garnered 22 citations, establishing a foundational framework for nerve-sparing robot-assisted radical prostatectomy (RARP). More recently, his 2024 study on ICG fluorescence-assisted nerve-sparing RARP, with 3 citations to date, introduces a novel method using indocyanine green to enhance visualization of neural structures during surgery. This innovative approach aims to improve both subjective and objective outcomes for patients, including better preservation of lower urinary tract symptoms. Aoyagi’s work is notable for its practical impact on surgical practice, offering urologists a comprehensive, evidence-based strategy to optimize postoperative quality of life. His research continues to shape the evolution of robotic prostatectomy, making him a key figure in advancing patient-centered urologic oncology.
