In many, or perhaps the majority of cases I would put my money on yes. When I had my second reversal this was actually part of the topic. I don't think all the relief I got from my second reversal was just being open. When my second reversal failed, I did not regress all the way back to what I was post reversal 1. Post reversal 1, I had a lot of abdominal pains way out of my recovery. My second recovery wasn't loaded with abdominal pains.
Pvps is some complicated stuff, and a bit individualized. I find it more difficult to figure out when some have multiple issues, aka, varicocele pain, pvps, etc.
When my second reversal failed, I began to wonder how many must be failing as well. Perhaps its just me, but I'd put my money on failure is very common down the road. Where are all the guys that failed, and are in major pain again.
This stuff is definitely a bit hit and miss, and statistics prove that.
What about reversals that are done in such a way where they leave the scarring, clips, granuloma left intact in fear of more pain as the outcome. I'd like to see controlled statistics on that way, vs the full clean up method. Personally, I'm not a fan of leaving all the foreign stuff intact during a reversal.
