Until 2 months ago, I could pee normally, one single stream going just
where I pointed it, except once every 6 months or so, the sides of the
opening were stuck together for a minute or so, but that was so rare
it was no problem.
But recently, *I had blood in my urine and the urologist sent a scope
up my urethra to look inside my bladder, then on another day something
else to do a bladder biopsy (negative), and 10 days after that, a
laser to zap a bladder stone, almost as big as a golf ball. .
Between the 2nd and last procedure I had 3 different catheters, and
after the last procedure, abother thicker, stiffer one with a bigger
channel inside, to allow any remaining *little particles from the
stone to come out. * Everything is fine now, no more blood, except now
I almost always pee in 2 or 3 streams going in all directions and it
makes a mess if I'm standing up.
In response to this problem, the doctor thought I need a smaller
prostate, either with a stronger drug or a laser-sapping (this time
the prostate itself, not the bladder stone (which is gone).
But the prostate is several inches from the opening, at the end.
Wouldn't any turbulence caused by a narrow opening due to a enlarged
prostate(*) even itself out before the exit point, *even if we
understated the distance as 3 or 2 inches), and doesn't that mean the
obstruction is quite close to the opening?????
*And not where the prostate is. * After all, I was peeing normally
until the day before the 2nd procedure, and even though the outside
catheter surface is smooth, I can't help thinking it messed something
up near the exit point, maybe when one of the four were coming out.
*(which is probably no more enlarged than it was 14 days earlier,
before the 2nd procuedure) )
Background. *The tube leading to the opening is called the urethra,
but the tube ends (or starts) where the prostate is, and from there up
to the bladder, there is no tube just a space made by the lobes of the
prostate. * At least this is approximately right, and it's why it's
possible to zap the prostate with a laser without cutting through the
urethra, or needing to sew it back up.
I don't mind posted replies, in fact they are better because other
people reply to them,, but if anyone wants to email, remove the extra
r's after onlooker. *There should be only one.
OP-
I was inclined to point the finger at "nozzle problems" but this
exerpt seems to indicate other issues as well.
Be very certain of the diagonsis before letting anyone mess with the
prostate.
I would have figured that the flow would sort itself out if the
disruption tool place at the prostate.
Be careful, lots of docs suck at diagnosis.

Splitting of the urinary stream is very common. It occurs when there
exists an area of relative narrowing of the urinary canal (urethra).
This may occur anywhere in the urethra from the neck of the bladder to
the opening of the urethra at the end of the penis (meatus). The most
common causes are an enlarged or swollen prostate gland, urethral
strictures or meatal stenosis. Another frequent cause is in those men
who remove their penis through the unzippered fly, void and then put
the penis back. Often, the space is not adequate for total free flow
as the lower (bottom) edge of the fly can actually push on the urethra
causing urine to be trapped. This phenomenon can be totally avoided
by dropping your trousers and then urinating in the standing or
sitting position. When the urinary bladder is full (such as from a
diuretic or delaying the desire to void) or if one voluntarily strains
to void, the pressure of the stream can be increased and the stream is
often more full and forceful without the split.
To determine the etiology and potential seriousness of a split stream
requires consultation with a urologist. A urinalysis, observation of
the voided stream and uroflowmetrometry (to determine if the force of
the stream is normal) are generally done. If there is a question
about the ability of the bladder to empty properly, a determination of
the residual urine can be done either by a bladder ultrasound or
catheterization. Sometimes, a cystoscopic examination is also
necessary to determine the cause of the problem. Many patients with
split streams require no specific treatment. However, significant
restriction of the urine flow, residual urine, or infection are
indications for treatment. The latter, of course, depends on the
underlying etiology.
