Early outcomes of robot-assisted radical prostatectomy following completion of a structured training curriculum: a single surgeon cohort study

Abstract

Objective: Technical skills in robot-assisted radical prostatectomy (RARP) are not mandated by the Intercollegiate Surgical Curriculum Programme. The European Association of Urology Robotic Urology Section (ERUS) developed a structured curriculum; however, surgeons’ outcomes data from subsequent independent practice are limited. We describe the initial post-ERUS curriculum RARP outcomes for a United Kingdom (UK)-based surgeon. Patients and methods: This was a prospective single surgeon cohort study of 272 patients who underwent RARP between February 2016 and October 2019 in a high-volume UK centre and who were followed up at approximately 3 and 12 months. Positive surgical margins (PSMs), and 3- and 12-month continence rates were obtained and used to generate learning curves, with point of plateau estimated from logarithmic trendlines. Results: Overall (⩾3 mm) PSM rate for pT2 was 14.9% (5.4%) and pT3 was 22.6% (3.2%). Where data were available, 70.5% (of n=251) and 95.5% (of n=154) patients achieved social continence (0–1 pads) at 3 and 12 months, respectively. PSM and 3-month social continence rates plateaued at ~175 and ~100 cases, respectively. Conclusion: Following completion of the ERUS RARP curriculum, early oncological and functional outcomes consistent with published standards are rapidly achievable in independent practice. These data exemplify the potential value of a standardised RARP training curriculum to mitigate possible compromises in outcomes. Level of evidence: IV
