About
J.A. Witjes is a leading urological surgeon and researcher whose work centers on advancing robotic surgery in urology, with a particular focus on training, skill assessment, and clinical outcomes for bladder and prostate cancer. His most influential contribution is the development and validation of the da Vinci Skills Simulator, a foundational tool for assessing learning curves and establishing criterion-based training for robotic basic skills—a study that has garnered 50 citations and shaped how surgical proficiency is measured. Witjes also conducted a pivotal cost-effectiveness modeling study comparing robot-assisted radical cystectomy (RARC) to open surgery for bladder cancer, which, with 29 citations, provides critical evidence to guide future research and healthcare resource allocation. His work extends to training pathways for the first generation of robot urologists, offering essential insights into ideal training for future surgeons. More recently, Witjes has contributed to predictive modeling with a nomogram for side-specific extraprostatic extension in prostate cancer patients undergoing robot-assisted radical prostatectomy (RARP), and a nationwide study on the impact of positive surgical margins after cystectomy on oncological outcomes. Through these efforts, Witjes has significantly advanced both the science and practice of robotic urologic surgery.
