About
Dr. Keiichi Tozawa is a leading Japanese urologic surgeon whose research focuses on advancing robotic-assisted surgery for prostate cancer, urinary incontinence, and pediatric urologic conditions. His major contributions center on refining robot-assisted radical prostatectomy (RARP) techniques to improve patient outcomes. Notably, his work on the bladder neck sling suspension technique (40 citations) demonstrated a significant improvement in early return of urinary continence, a critical quality-of-life concern. He also pioneered the extravesical robot-assisted laparoscopic ureteral reimplantation using the ureteral advancement technique for vesicoureteral reflux (38 citations), marking an important step in minimally invasive pediatric urology. Tozawa’s impact is evident in his multi-institutional study using a national database (18 citations), which established that higher surgeon and hospital volumes are directly linked to safer RARP outcomes. His comparative analysis of positive surgical margins between robotic and laparoscopic surgery (17 citations) provided essential safety benchmarks. With over 200 combined citations across his top ten papers, Dr. Tozawa’s work has shaped best practices in robotic urologic surgery, particularly in Japan, and continues to influence surgical approaches for improved functional recovery and oncologic safety.
