Che-Rei Yang

About

Dr. Che-Rei Yang is a urologic surgeon and researcher whose work centers on refining surgical outcomes in nephron-sparing surgery, particularly partial nephrectomy. His primary research area involves developing quantitative, mathematical models to predict postoperative renal function, moving beyond traditional anatomical scoring systems. Dr. Yang’s most significant contribution is the introduction of the Tumor Contact Surface Area (CSA), a calculus-based formula that precisely calculates the interface between a renal tumor and healthy kidney parenchyma. In his landmark 2016 study, which has garnered 40 citations, he demonstrated that CSA is a powerful, independent predictor of renal function loss after partial nephrectomy, outperforming conventional metrics. He further validated this approach in a subsequent head-to-head comparison of new-generation nephrometry systems, showing that CSA correlates more strongly with ischemic volume and functional decline than other volumetric parameters. By providing a more accurate, reproducible tool for surgical planning, Dr. Yang’s work helps urologists better predict patient outcomes, optimize resection strategies, and preserve kidney function—a critical advancement for patients with renal masses.
