Rich Environment of Active Research
Recognition of the need for a personalized approach to medicine has long been a focus of the Department of Surgery and Division of Urology initiatives. The impact of treatment-related morbidity and the burden of urologic diseases on national healthcare expenditures mandate improved ability to select patients for appropriate treatments and to predict outcomes. Evaluation of healthcare outcomes and comparative treatment efﬁcacies is a key component of our healthcare outcomes, policy initiatives and an intense area of research focus for the division.
Health Services Research
Faculty within the Division of Urology actively engage in multi-disciplinary investigation to improve the quality and value of health care delivered to patients with benign and malignant urologic disease. Faculty within the Division continue to lead landmark studies characterizing the downstream effects of bladder cancer and its treatment. Furthermore, ongoing research within the Division seeks to bridge the gap between health services research and quality improvement to optimize care delivered to patients at UTMB and across the United States.

Stephen B. Williams, M.D. is Director of Urologic Research, and he is also Co-Director of the Department of Surgery Clinical Outcomes Research Program. Dr. Williams has expertise in health services research. His seminal research in comparative effectiveness regarding prostate cancer treatments has fueled his more recent interest in regards to discerning bladder cancer treatment patterns and optimizing outcomes. His research has been presented at the National Academies of Sciences, Engineering, and Medicine (previously known as the Institute of Medicine). He was named the Comparative Effectiveness in Research on Cancer in Texas (CERCIT) Scholar and his work will help pave the way for further understanding and optimizing the care we deliver to these patients.
