There are a couple of other things you may want to be aware of and I will describe how they have affected me.
First, as you heal, some scar tissue will tend to form at the junction of the neobladder. This would make it progressively more difficult to urinate and be complicated by the build up of mucus from the neobladder which would tend to form sort of a dam that would reduce/block urination. Each visit to the Uro I would urinate into a device which would measure both volume and rate. Immediately following this, they would use another sonogram type device to measure the residual urine in the bladder and I was starting to not empty fully.
My Uro first tried to push it out of the way using (don't quite remember) either a cath or a flexible cystosccope (or some such instrument). This was only successful temporarily. He followed that with a laser device which he inserted to zap some of the scar tissue. I did have to have a cath for about 2 days after that. As a side note, I had asked them for the items I would need to flush the cath from mucus. They said I wouldn't need it ---heh,heh,heh, so naturally, I needed it that night when I blocked up. Fortunately I had a sealed liter of medically sterile water which I use in my water cooled computer. My wife went out looking for a syringe for the water but was unsuccessful at night. I improvised with a turkey baster (the family heirloom turkey baster which now had to be replaced). It worked well enough to get me thru the night without having to go to an emergency room. We got a regular syringe in the morning from a local med supply store and the cath was removed the next day.
That was in January and the procedure is still good, although it has closed up a bit since then. Generally there is enough clearance so mucus blocks can be expelled without too much trouble. My point is that if you are having difficulty urinating, they can give you relief.
You might also note a difference in your ability to urinate at different times of day. I found I am best from early morning to late afternoon and then I seem to lose power and am a little blocked (I am sitting all day and guess it may be partially from that). My ability returns by late evening and seems to fully rebuild with sleep. My guess is that is 'normal'
