Overview

Retrospective study evaluates learning curves of robot-assisted prostate surgery, indicating variable skill progression across steps.

Key Points

  • To assess overall and step-specific learning curves of extraperitoneal SP-RARP during the initial adoption phase.
  • Retrospective analysis of 31 patients with localized prostate cancer undergoing SP-RARP.
  • Surgical procedures divided into nine predefined steps; metrics included console time, operative time, and blood loss.
  • Cumulative sum analysis and segmented regression utilized to identify learning breakpoints.
  • Median console time was 162 min (IQR, 153–184 min) with a breakpoint around cases 16-17.
  • Blood loss stabilization occurred earlier at approximately cases 3-4.
  • Step-specific analyses revealed varying stabilization times across surgical steps, with some steps maturing faster than others.
