It'll get read. :)
Wow! Thanks for sharing. I had not heard of this for RPs! I'm fascinated!
So, you probably know all about
this already, island time, but I don't recall earlier discussion on this anywhere at HW/PC; has there been, or are you the first? A HW/PC pioneer? Anyhow, I learned a few things here in the last few minutes which I'll share, but I'll ask you to add/fill-in as needed...others may be interested in this in the future
The Amniotic Membrane (AM) is the inner layer of the placenta that surrounds the baby during pregnancy, and consists of the amnion layer and chorion layer. Tissue is gathered via elective "donation;" donor eligibility requires a live mother to have given full consent and to have delivered a live birth via elective Cesarean section. (There's actually a business formed that is in the market to collect and re-distribute these.)
While the basis for this therapeutic effect has not been fully elucidated, native human amnion/chorion membrane contains an array of growth factors that are known to play critical roles in the physiological processes leading to normal wound healing and tissue regeneration. I've previously heard of this being used for burn healing, but the idea to improve continence and potency recovery is new in the last few years...a study paper presented at the World Congress of Endourology in 2014 was claimed to be the first-ever.
The study's author, who said that the procedure is not particularly challenging but that there is a definite learning curve, gave this interesting descript
ion at the presentation:
"Once the prostatectomy is completed but before the urethral anastomosis is conducted, the membrane is passed to the site via a 12-mm side port,” he explained. “My assistant rolls up the membrane, which is like parchment. It has to remain perfectly dry as it passes through the port because if it gets wet, you can't handle it. I grab it with the robotic arm and depending on the thickness and width of the neurovascular bundle, it can be placed as one sheet or if the bundles are wide apart, it can be cut into two sheets.
“It is wrapped around the nerve. The moment it gets moist, it sticks. There is no need for sutures. The sides are labeled 'up' and 'down.' The 'down' side goes onto the nerve. Otherwise, it will not stick."
Very interesting!
Did you have this done in Florida by Dr Patel (I see his name pop up a lot with this topic)? You also had the iatrogenic PSM, as I recall, right? As I said, others may be interested in learning more about
this new technique in the future...
