We perform a multicenter randomized controlled prospective study with superiority trial design, in which the polysaccharide ARISTA™ AH hemostat agent is applied to the neurovascular bundle areas after prostate removal, during Robot-assisted radical prostatectomy.
We examine if such agent leads to a relevant clinical improvement indicated by higher postoperative hemoglobin levels compared to the control group. As an exploratory co-primary endpoint of interest, we examine erectile function after Robot-assisted radical prostatectomy based on IIEF-5 score between groups 3, 6 and 12 months after Robot-assisted radical prostatectomy
