Hello John,

That was exactly my situation before PVP last August. I assumed it was
normal i.e. the bladder muscles are hard to get going in the morning
just like any other when you get older ( I am 68 ) Just
drip,drip,dibble.

After PVP the flow is many times better but in the early hours of the
morning the flow is still less, maybe only 70%.

Like you say,after half an hour of activity,everything is fine again.

To sound a warning, I ended up with complete retention in the middle
of the night, off to the Emergency Ward then a catheter for 4
days.Only once,but that was enough. Before the PVP Op I kept retention
at bay for 5 weeks by walking for half an hour before bed at midnight
and setting the alarm to go off every 2 hours to empty the bladder 3
times a night.

I asked my uro about this because it's the same with me (don't have the
problem at night though).  He said as the bladder stretches it loses
elasticity so when it gets overstretched, there isn't much strength left to
squeeze which is why the flow is slow when you wait too long.

The above was exactly the reason I went looking for a PVP procedure.

There are intelligent urologists?

I have urgency, so during the day my system makes sure I pee when I
need to. If for some reason I don't or can't (for instance, stuck in
the dentist's chair), then my bladder gets over-full and then I have
very slow flow, and it takes much effort and time to get the system
back under control.

At night I don't have urgency because I am asleep. Therefore sometimes
I wake up overfull, and then I am in trouble with very slow flow. On
occasion I've gone into retention.

The nocturnal problems are much worse if the total volume of pee
during the night is a lot. The effect is more than I would have
expected. So, if I produce only 200-300 mL, I get up maybe once and
flow is good. But if I make 800 mL, then I get up 3-4 times and can
experience great discomfort each time.

I used to think there was something about night time that made it
worse, and I still think that might be a factor, but for me
overfilling of the bladder is probably more important. One time I woke
up with a very full bladder at exactly the time the alarm went off,
and had much difficulty for 1 1/2 hours during the broad daylight of
early morning.

Just my experience...

I realize that Newtonian thought had gravity accounting for the macroscopic
behavior of the universe. Now I just found out that it also describes
relatively microscopic behavior of my bladder. I still need a translation
from the Latin so that I can understand.
