Clinical Trial 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).

Description:

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.

Secondary	Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores	Overall patient satisfaction Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) - composed of 29 items - the survey contains 19 core questions about critical aspects of patients' hospital experiences (communication with nurses and doctors, the responsiveness of hospital staff, the cleanliness and quietness of the hospital environment, communication about medicines, discharge information, overall rating of hospital, and would they recommend the hospital) - HCAHPS score is accounted as The "top-box" score indicates how often patients selected the most positive response category when asked about their hospital experience. The higher a hospital's "top-box" score, the higher it ranks.	Day 1 post-op
