V46 Prospective evaluation of the Surface-Intermediate-Base (SIB) margin score for standardized reporting of resection technique during robot-assisted partial nephrectomy (RAPN) in a high-volume center: A step-by-step tutorial

Tumour excision (TEx) is a fundamental step during partial nephrectomy (PN), yet underreported in the current series. We introduce the concepts of resection strategy (RS, the surgeon’s preoperative intent) and resection technique (RT, the actual surgical result) to describe the complexity of TEx during PN in a standardized way (Fig. 1). In this video we describe a tutorial guide for the evaluation of the Surface-Intermediate-Base (SIB) Margin score as a standardized scoring system of RT during robot-assisted partial nephrectomy (RAPN) at a high-volume center.
