About

Samuel D. Kaffenberger is a urologic surgeon and researcher whose work centers on surgical oncology, with a particular emphasis on prostate and bladder cancer management. He is best known for his pioneering contributions to salvage robotic-assisted laparoscopic radical prostatectomy (RALRP), a technically demanding procedure for patients with recurrent prostate cancer following primary treatment. His 2012 landmark study — now with 79 citations — presented the largest single-institution series of salvage RALRP at the time, providing critical data on patient selection, complication rates, and oncologic outcomes that helped shape the field's understanding of this complex intervention. Building on this foundation, Kaffenberger continued refining the evidence base for salvage robotic prostatectomy through subsequent publications in 2014. His research portfolio extends beyond prostate cancer to healthcare economics, notably examining real-world cost and perioperative differences between minimally invasive and open radical cystectomy for bladder cancer. More recently, he has investigated how evolving surgical techniques, including robotic adoption, affect long-term patient-reported functional outcomes. Through rigorous, outcomes-driven research within statewide quality improvement consortia, Kaffenberger has meaningfully advanced evidence-based urologic surgical practice.
