INTRODUCTION: The renal nephrometry scoring (RNS) system enables prediction the feasibility of nephron-sparing surgery (NSS) in renal masses. There is insufficient data regarding the outcome of robot-assisted NSS in tumors with RNS ≥10. We reviewed the trifecta outcomes of patients undergoing robotic NSS with high RNS and compare it with tumors of low and intermediate RNS. MATERIALS AND METHODS: Our prospectively maintained data of all robot-assisted NSS were reviewed, and those with RNS of ≥10 were identified...

Introduction Irreversible electroporation (IRE) is a non-thermal minimally invasive technique to treat small renal masses (SRM). Prior work has demonstrated greater narcotic requirements after radiofrequency ablation (RFA) for tumors closer to body-wall musculature. We hypothesized that pain after IRE is not dependent on tumor location due to the athermal mechanistic action. Methods Retrospective review of 50 consecutive percutaneous IRE and RFA cases was performed from 2013 to 2014. Eight patients were excluded from analysis due to incomplete anesthesia record and/or multiple ablations per session leaving 21 patients in each group...

REVIEW
Shreyas S Joshi, Robert G Uzzo
Anatomic tumor complexity can be objectively measured and reported using nephrometry. Various scoring systems have been developed in an attempt to correlate tumor complexity with intraoperative and postoperative outcomes. Nephrometry may also predict tumor biology in a noninvasive, reproducible manner. Other scoring systems can help predict surgical complexity and the likelihood of complications, independent of tumor characteristics. The accumulated data in this new field provide provocative evidence that objectifying anatomic complexity can consolidate reporting mechanisms and improve metrics of comparisons...
