Three-dimensional reconstruction-guided modified arterial-based complexity scoring system for nephron-sparing surgery: comparative outcomes of on-clamp and off-clamp tumor enucleation in renal cell carcinoma.

ABSTRACT:

Background

Various modalities of nephron-sparing surgery (NSS) exist; however, a comprehensive standard for determining the most suitable approach for specific kidney cancer patients remains elusive. This study aims to establish a novel scoring system that will assist urologists in formulating tailored surgical plans.

Methods

We conducted a comparative assessment of perioperative and prognostic data for these surgical types, alongside tumor contact surface area and arterial-based complexity of 205 patients for classification and regression analysis. Finally, a modified arterial-based complexity (mABC) scoring system was developed to enhance this assessment methodology.

Results

Despite no statistical differences in demographic data, we found that the off-clamp tumor en
