There are four features of the prostatic urethra seen immediately below. Furthest from view is the median lobe of the prostate which is positioned horizontally. Proximal to this is the bladder which cannot be seen due to the obstructive components of the prostate. Closer to the viewer are the median lobes of the prostate which come in to the channel of the prostate on the left and right and in addition to the median lobe cause the obstruction of urine flow. Then in the foreground is the verumonatum which is raised area in the prostate and where the seminal vesicles empty fluid from the seminal vesicles and testicles.
The significance of veru is that this represents the point of the prostate where the urologist stops the resection or laser treatment. Beyond the veru is the external sphincter and if this is resected or damaged then there is a risk of incontinence.
If you look closely at the veru you can see the small opening from which the above mentioned fluid emanates.
At the end of this GreenLight performed by Dr. McHugh, you’ll see the opened channel for the prostate from the bladder to the veru and the veru intact which means that the resection did no proceed beyond the point of compromising incontinence.
