TOPIC: Is PMMA considered a surgical operation?

Hi guys, I'm interested in enhancing my Girth but I can't understand one thing - is the PMMA procedure a surgery that you undergo? Correct me if I'm wrong, from what I've understood so far, it's something like a filler they add to your penis and that's it, you don't get cut etc and can go home the same day? I'm asking because I've had surgery on my femurs lately and combining two surgeries in short period of time isn't a good idea, if this is considered one.

All Dermal Filler injections for Girth enhancement, be it PMMA, Hyaluronic Acid (HA), Ellanse, and so on, are non-surgical, meaning they require no incisions and/or stitching, no general anesthesia (local anesthetics are used and you are awake during the procedure), and is outpatient (no overnight stay at the hospital or clinic). This is one of a few reasons they've become the popular choice for elective penis enlargement.
