continence and potency following multi-layer perinatal issue allograft

Conditions: Post Operative Recovery

Summary: the purpose of this research is to determine the effectiveness of using human umbilical cord (uc) allograft to help improve return to erectile function and bladder control in patients following robot-assisted radical prostatectomy (rarp).

participation in this study will involve mlg (multi-layered perinatal tissue allograft) allograft, which is implanted during the surgery. this allograft is currently fda approved and used for several type of surgeries. the multi-layered perinatal tissue allograft- (mlg) is processed from tissue according to the american association of tissue banks (aatb) standards, and is regulated as a cell, tissue, or cellular or tissue-based product (hct/p) under section 361 of the public health service act. the grafts are distributed by samaritan biologics, llc; an fda-registered tissue bank. the mlg allograft will be placed on each neurovascular bundle (nvb) bilaterally. mlg is supplied as sterile sheets having dimensions of 2cm x 2cm and a thickness of approximately 0.8-1.0mm thick. participants receiving mlg will have it placed around the neurovascular bundle. placement of the graft should not take over 5 minutes of time to impact overall surgical time length significantly.
