Histopathological Validation of the Surface-Intermediate-Base Margin Score for Standardized Reporting of Resection Technique during Nephron Sparing Surgery

Abstract

Purpose: The surface-intermediate-base margin score is a novel standardized reporting system of resection techniques during nephron sparing surgery. We validated the surgeon assessed surface-intermediate-base score with microscopic histopathological assessment of partial nephrectomy specimens.

Standardized Reporting of Microscopic Renal Tumor Margins: Introduction of the Renal Tumor Capsule Invasion Scoring System

“…5 The authors attempted to validate the scoring system in a follow up analysis. 29 The SIB scoring system provides is predicated on the surgeon's ability to accurately assess the presence or absence of residual parenchyma around various sections of the removed renal tumor. The i-Cap scoring system, determined by histopathological analysis, may function as an ideal complement to aforementioned SIB system in that it may provide a checks and balances to the surgeon's assessment on a microscopic level.…”

Laparoscopic retroperitoneal partial nephrectomy using an ergonomic chair: demonstration of technique and matched‐pair analysis

“…We prefer the enucleo‐resection technique, dissecting along the renal pyramids , even if results using enucleation around the pseudo‐capsule of the tumour have shown equivalent oncological outcomes . Recently, the Surface‐Intermediate‐Base Margin score has been introduced to standardize reporting of resection techniques during nephron‐sparing surgery . This will be very helpful for comparing the different resection techniques prospectively.…”

“…Despite the shorter WIT, postoperative renal function did not differ between the groups. The impact of ETHOS on surgeons' physical ergonomics has been studied extensively previously, showing a significant reduction of the mean complaint score from 31.6 (20-40) to 13.9 (13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24), mainly as a result of less shoulder stiffness, arm pain, hand pain, wrist stiffness, back and leg pain [12,13].…”

Tumour enucleation vs partial nephrectomy: Long term results

“…While, the actual postoperative surgical result (resection technique) could be classified according to a careful analysis of the specimen after surgery. In this regard, the Surface-Intermediate-Base (SIB) Margin score was recently proposed to provide the literature with a standardized reporting system of resection techniques during NSS and we recently validated the model from the histopathological perspective [1,2]. We have shown that the visual definitions of resection techniques used to calculate the score do significantly mirror histopathological analysis to quantify and report the thickness of healthy renal margin resected by the surgeon.…”
