RALUR is the minimally invasive alternative to open reimplantation for paediatric vesicoureteral reflux (VUR); however, its learning curve remains poorly defined due to small series and inconsistent outcome reporting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patients and methods<\/jats:title>\n                    <jats:p>We performed a retrospective single\u2010surgeon study of 125 patients undergoing RALUR for primary VUR divided into pre\u2010LUAA (2008\u20132011), evolving LUAA (2011\u20132014) and standardized LUAA (2014\u20132025) phases. The primary outcome was radiographic VUR resolution on postoperative voiding cystourethrogram.
