Anatomic Complexity of Renal Masses and Outcomes of Minimally Invasive Partial Nephrectomy: Do We Have an Answer?

摘要

Whenever feasible, nephron-sparing surgery (NSS) offers the ultimate treatment option to patients presenting with small renal masses. With the evolution of minimally invasive surgery, the rate of NSS is also on the rise [1]. Substantial efforts have been made to develop a standardized classification system to objectively determine the complexity of a renal mass and ultimately predict the outcomes of NSS. The C-index method, PADUA, and RENAL nephrometry scores signify such efforts (Table 1) [2-4].In this issue of European Urology, Leslie et al. take a step toward further identifying factors that could affect the outcomes of NSS [5]. The authors define renal tumor contact surface area (CSA) as a product of tumor size and degree of intraparenchymal extension.
