About

Kazunori Hattori is a leading Japanese urologic surgeon whose research focuses on optimizing robot-assisted radical prostatectomy (RARP) and partial nephrectomy for prostate and renal cancers. His major contributions include pioneering a novel, simplified inguinal hernia prevention technique during RARP that avoids artificial substances, demonstrating durable long-term efficacy (7–39 citations). He has also advanced the use of indocyanine green-guided extended pelvic lymph node dissection to improve diagnostic accuracy in intermediate- to high-risk prostate cancer (21 citations). Through multi-institutional prospective studies, Hattori has established benchmarks for robotic partial nephrectomy outcomes in Japan, including long-term oncological and functional results with minimum five-year follow-up (13–14 citations). His work on surgeon-specific learning curves using cumulative sum analysis (8 citations) provides valuable guidance for training and quality improvement. With over 140 total citations across his most-cited papers, Hattori’s research directly enhances surgical safety, reduces postoperative complications, and refines lymph node dissection strategies, making him a key contributor to evidence-based robotic urologic surgery.
