Introduction: Incontinence (up to 20%) and erectile dysfunction (up to 70%) occur frequently after radical prostatectomy (RP) in patients with localized prostate cancer. Human amniotic membrane (HAM) can improve tissue regeneration and functional outcome after RP owing to the growth factors and unique immune tolerance. Preliminary studies showed the potential value of HAM in the reconstruction of the urinary tract and nerve protection during RP. Methods: A protocol is developed for a prospective, randomized, single-blind, singlesurgeon, placebo-controlled exploration study of the efficacy and safety of dehydrated human amnion membrane placed around the neurovascular bundle (NVB) and vesicourethral anastomosis (VUA) during RP for the treatment of localized prostate cancer. Eligible for inclusion are patients with localized prostate cancer, requiring a surgical procedure and exclusion of preoperative incontinence and erectile dysfunction. The patients are randomized 1:1 to HAM vs. placebo and blinded during the study Enhanced Digital Features To view enhanced digital features for this article go to https://doi.org/10.6084/ m9.figshare.10283555.
