Kana Kohashiguchi

About

Dr. Kana Kohashiguchi is a urologic surgeon whose research focuses on improving functional outcomes and oncological safety in robot-assisted laparoscopic prostatectomy (RARP). Her work centers on two critical aspects of prostate cancer surgery: minimizing post-operative complications and optimizing nerve-sparing techniques to preserve urinary continence. In her highly cited 2022 study, Dr. Kohashiguchi investigated how the severity of urethrovesical anastomotic leakage impacts urinary continence recovery following RARP, providing surgeons with actionable insights to reduce post-operative morbidity. More recently, in 2025, she has advanced the field by proposing a refined patient selection strategy for nerve-sparing RARP, demonstrating that the absence of PI-RADS ≥3 lesions or Gleason pattern ≥4 on biopsy in the peripheral zone can safely guide nerve preservation without compromising oncological outcomes. Her work bridges the gap between aggressive cancer control and quality-of-life preservation, offering a personalized approach to surgical planning. With growing recognition in the urology community, Dr. Kohashiguchi’s contributions are shaping evidence-based protocols that help patients recover faster and maintain better urinary function after prostate cancer surgery.
