You drained yourself right after you urinated and got another 600ml?  That's
an awful lot.  How much volume do you urinate as a rule? Jim W.

My laymans answer is that you have a median lobe protruding into your
bladder which is stopping the flow of urine.  The TUNA procedure
opened a channel which is working fine until the median lobe stops the
flow.  This is one of the downsides to TUNA and PVP.  I believe that
TURP is more effective for this type of blockage, but one will
probably have retro as a result.

Reading your post I noticed a similarity of your symptoms to my own,I had a
laser turp done in December(not PVP)
I seemed to recover from the op fine and was peeing a lot better but not a
lot of volume about 250ml max but felt quite
empty after it. I thought the volume would increase gradually as my system
recovered from the op.
I attended the routine post op clinic about a month after the op.and was
scanned to see how much I was retaining in my bladder, I expected it to be
only a small amount
as I felt I was empty,I was shocked to find I had over 500ml,they were going
to put another indwelling catheter in me but I had one those in me for over
four months before my op so I did,nt fancy the discomfort and possible
bladder infections they caused before again,so they suggested self
catheterisation which I agreed to and have been doing it  for about a month
now 3 times daily.
It seems that over the years I had BPH problems my bladder had lost its
ability to empty properly and so I must have been going around with my
bladder never completely empty
Before my op and before I went into total retention although I was passing
urine in small quantities every couple of hours i was never bothered by
needing to get up during the night.
I think if I had I would have been more anxious about my condition and
sought medical help sooner,as it was I was just living with it as no more
than an annoying condition to put up with.
As far as I know the bladder sometimes can recover its ability to empty
completely depending on how severe the damage is , I personally am not too
hopeful,however I have found self catheterisation to be far easier than I
thought and now do it no problem.
By the way it would not matter what kind of op I had TURP or PVP the bladder
condition was there already.

It went very well, fast recovery and I now

Hi Zork,
I've had a PVP a couple of weeks ago, and some of my symptoms have
improved, like yours, but others haven't. Here's how I understand
that.

I think we have a mistaken idea of what to expect, because our
condition is described as an enlarged prostate. That is incorrect.
Actually, what we suffer from is a damaged bladder caused by an
enlarged prostate. When the obstructed urethra is cleared by any of
the operations on the prostate, we get that wonderful relief of a much
stronger stream, but the bladder can still take a long time to get
back to normal.

Specifically, the bladder gets stretched, very muscular, and loses
control. It continues to push very hard at first, until it gets used
to not needing to do so and gets less muscular. It takes a while to
become able to empty fully, which is what you found with your
catheter.

I think you are lucky to be able to sleep through the night. I have
had no improvement in that yet, although I am able to get back to bed
and back to sleep more quickly. I still have a spurt of blood when a
start to pee. My uro, Tim Larner, says all of this is quite normal
after PVP. He says that sleeping through the night is often the last
change to come. Overall, after two weeks, I am still extremely pleased
with the results of my PVP, despite some symptoms remaining. The
biggest relief is the end of that terrible pushing and spasming of my
bladder when I peed, and the interminable time it took to pee.

Regards,
Gary

There is another possibility, some what rare.  Over time, as the bladder
experienced high pressures caused by the blockage, a diverticulum, or
"balloon" as some call it, may have formed.  This is where the wall of
the bladder expands to form another reservoir that can be as large or
larger than the bladder itself.  It doesn't have muscle though and so it
doesn't drain well.  What could happen is your bladder could be emptying
just fine, in fact it may push some of the flow into the diverticum as
well, but you could have a diverticulum holding the 600ml which then
drains into the bladder after it is empty.  You should have flow tests
where they use a dye that can be seem in xrays to determine if you have
this condition.  If you do, the only answer is open surgery to remove it
or do nothing.  Infections would be a reason to take action.  However
it's something you may want to know about because it may be your bladder
is functioning just fine but it's the diverticulum retaining that makes
it look like other problems.
