The above may have been gleaned from my profile (I haven't posted a great deal on ED specifics).
Hopefully you have a date booked now and made decision, you seem 'similar' profile to me. We took decison from MDT.
We were realistic and well informed : Expect the worse, and we hoped for the best as we say: plenty of options if ED. A friend of a friend had an penile implant on NHS ! (not for me though)
However nearly 3 years post op, progressing very well last few months. Briefly, Kegel must help and use it or loss it . Try not to give up and try various solutions. ie PDE5 inhibitors (tried various for few months, first 12 months, no use if no nerve signals - gave up - headaches also ). Alprostadil (Vitaros cream) - thanks to Chris (very informed member) who told me about this. Used to minimal effect and gave up on that. However erection lasting longer and stronger, so we kept positive.
Yes, agree it's all a palaver and cross the bridge as you need to. Nerves and blood vessels will be severely traumatised and need 2 to 3 months to fully recover. We were more concerned re. urethral anastomosis / stricture and continence, so anything else was a real bonus.
As an aside - urine flow has been better than before, control great. I was probably very lucky (see profile for more detail). Very occasionally climacturia, although this subsiding.
All the best
