Gents - thanks to all of you who replied to this post. Much appreciated. The advice I was given re food/fasting seems specific to the hospital I was treated at and doesn't seem the norm. Also I wasn't allowed solid food after the op for almost 24 hours whereas I've read guys saying they were offered food shortly after coming round in Recovery.
Anyway, as I said initially, this is pretty trivial in the whole scheme of things. The good news for me is the op sounds like it went very well with complete nerve sparing and clear margins. I have some incontinence post catheter removal but know that is very common.
Thanks again.
