When there is non-nerve sparing on one side, does it mean that there is more incontinece issues, or does non-nerve sparing only relate to increased erection issues?   Very confusing.  They took out nerves on one side, but spared nerves on the other side.  
And what does it mean focal perineural invasion?  Thanks.

I can't give  you a real answer, but my own personal experience was that they were only able to save the nerves on my right side.  Nevertheless, I never had a real problem with incontinence (wore the same pad all day from the start), and was completely dry at about the 8-week mark.  So, at least in my case, non-nerve sparing did not equate with incontinence problems. 
I also don't know what "focal perineural invasion" means.  Sorry.

"Nerve-sparing" is all to do with the erectile nerves, and is independent of the urinary sphincter nerves.

I was non-nerve-spared and was fully continent from the day the catheter came out. As expected, I had (and still have) ED, but it's not so bad :-)

Some guys here have only one side spared and are fully functional (with erections) from day one. Others have both sides "spared" and never recover. What ultimately happens is very variable, and it's impossible to predict individual cases.

I'll have a shot at defining "focal perineural invasion" -- if I have anything wrong, I'm sure a more knowledgeable member will correct me:

Perineural invasion is where the PCa invades the internal nerves of the prostate. These nerves are the path of least resistance, so perineural invasion is the norm. The definition of "focal" means it is confined to just a few places, so I would take that as a good sign.
No symptoms; PSA 5.7; Gleason 4+5=9; cancer in 4/12 cores

Organ confined, neg margins. Gleason downgrade 4+4=8
Fully continent
Bimix worked well; now using just VED
PSA undetectable at first but then rose to 0.4, doubling time 7 months
Following diet change, PSA static at 0.4...

I had non-nerve sparring surgery and have not really had an issue with incontinence since catheter removal. ED function is a problem and I have started a regimen of daily ciallis (well every other day) with some results. No full erection yet, but I have become a shower, not a grower. LOL
