Surgeons were stratified by experience (&lt;\u2009100 vs. \u2265\u2009100 prior ERBTs). Primary outcomes included detrusor muscle presence, margin positivity, recurrence, and progression rates.

Mean operative efficiency was 2.07\u2009\u00b1\u20091.13\u2009min\/mm overall, and high experienced surgeons demonstrated greater efficiency (1.71\u2009\u00b1\u20090.89 vs. 2.64\u2009\u00b1\u20091.24\u2009min\/mm).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>ERBT is a safe and reproducible procedure that can be effectively performed by supervised trainees with outcomes equivalent to those of senior surgeons.
