235 Identifying surgical factors predicting postoperative urinary continence in robot-assisted radical prostatectomy Prediction of continence by the surgeon who performed the surgery and the independent expert surgeon The videos were evaluated by two expert surgeons (the surgeon who performed the surgery (HvdP, self-assessment, hereafter called Expert 1) and an independent expert in RARP (JPvB, expert assessment, hereafter called Expert 2)). The experts were blinded for the patients’ postoperative status and were asked to evaluate all proFigure 2 overview of the video analysis software Digital Video Coach. cedures. The predictions were performed on the prostate apical dissection phase and vesico-urethral anastomosis phase of the RARP procedure for continency prediction, and neurovascular bundle dissection for potency prediction. The experts were asked to predict the likely postoperative outcome of the patient in absolute terms of continency/incontinence. Additional information concerning the basis of this prediction was asked during analysis of the surgical video. After prediction the results of the experts were compared with the postoperative status of the patients.
