About

Naoki Kohei is a urologic surgeon and researcher whose work centers on the surgical management of urologic cancers, with a particular focus on optimizing outcomes in radical cystectomy and prostatectomy. His most cited case report, "Small bowel obstruction due to internal hernia caused by the ureter after laparoscopic radical cystectomy and ileal conduit" (2018, 9 citations), provides a critical cautionary note on a rare but serious postoperative complication, demonstrating his commitment to improving patient safety in complex reconstructive surgeries. More recently, Kohei has tackled a pressing debate in urologic oncology with his 2025 study "Reevaluating the therapeutic role of extended lymph node dissection in the era of robot-assisted radical prostatectomy" (3 citations). By analyzing data from over 8,000 patients, he offers real-world evidence on the oncological efficacy of extended pelvic lymph node dissection during robot-assisted radical prostatectomy, challenging and refining existing surgical guidelines. His work bridges the gap between traditional open techniques and modern minimally invasive approaches, providing actionable insights for surgeons navigating the evolving landscape of robotic urology.
