About
Dr. Alan Sim is a urologic surgeon and researcher whose work focuses on optimizing perioperative care for patients undergoing major urologic oncology surgeries, particularly robot-assisted radical cystectomy. His primary research areas include enhanced recovery after surgery (ERAS) protocols, multimodal pain management, and the impact of anesthetic techniques on oncologic outcomes. Dr. Sim’s major contributions center on the development and prospective implementation of nonopioid analgesic protocols, demonstrating that opioid-sparing pathways can effectively manage postoperative pain while reducing narcotic use. His landmark 2019 study, with 34 citations, pioneered a nonopioid protocol for extracorporeal urinary diversion, while his 2021 work extended this approach to intracorporeal diversion. Notably, his 2020 retrospective analysis of 23 citations explored whether anesthetic technique—total intravenous versus volatile anesthesia—could influence bladder cancer recurrence, a provocative area with significant clinical implications. Dr. Sim also led the UROTAP randomized trial, comparing robot-assisted, ultrasound-guided, and local anesthesia-based transversus abdominis plane blocks for pain control. His cumulative work has helped shape modern perioperative pathways in urologic oncology, emphasizing patient safety, reduced opioid exposure, and improved recovery outcomes.
