Let's look at an example of the anterior
0:03
form of BPH, so-called lobar type 1.
0:08
Type 1 in the front, type 2 posterosuperior
0:11
in the back behind the urethra,
0:14
type 3 balanced, both hypertrophied equally,
0:17
and type 4 pedunculated masses often arising in
0:21
the periurethral region, prolapsing into
0:25
and compressing the urethra would be a type 4.
0:27
So this is a type 1.
0:29
Most of the gland that's enlarged
0:32
is in front of the urethra.
0:34
So where is the urethra, you might ask?
0:37
It's a little hard to see,
0:38
but there's the opening right there.
0:40
And this dark slit represents the upper
0:43
portion of the urethra that has no
0:45
fluid in it because it's compressed.
0:48
In the axial projection, you can often
0:50
find urethra in front of the veru
0:53
montanum and the prostatic utricle.
0:55
So here's the utricle, the great landmark,
0:58
the smooth muscle, dark area in front of it is the
1:00
veru montanum, not a big one, and then the
1:04
little dot in front of that is the urethra.
1:06
So where's the urethra?
1:08
Back here.
1:09
So now you know that most of the gland that's
1:11
enlarged is in front of the urethra, only a little
1:16
bit of the gland that's big is behind the urethra.
1:19
The urethra is right there, this dark
1:22
irregular crack, and so this would
1:25
be a type 1 lobar hypertrophy.
1:29
And then you would go on to measure length
1:31
times width times height, and then pick
1:34
whether you're going to use the ellipsoid
1:35
or bullet technique to calculate the
1:37
volume of this prostate, which is pretty big.
