About

Daniel Melecchi Freitas is a urologic surgeon and researcher whose work centers on advancing robotic surgical techniques to improve outcomes in complex urologic oncology. His most impactful contribution addresses a critical complication in bladder cancer surgery: uretero-enteric strictures following robot-assisted radical cystectomy (RARC). In a highly cited 2019 study (89 citations), Dr. Freitas demonstrated that using indocyanine green (ICG) to assess ureteric vascularity during RARC significantly reduces stricture rates, offering a practical, real-time solution to enhance patient recovery and preserve renal function. This work has influenced intraoperative protocols in minimally invasive urology. He has also explored the role of robotic adrenal metastasectomy for oligometastatic castrate-resistant prostate cancer, documenting durable biochemical responses in select patients, and contributed to the literature on robot-assisted simple prostatectomy. Dr. Freitas’s research bridges surgical innovation with tangible patient benefits, establishing him as a contributor to the evolution of robotic urologic surgery.
