Note the inhomogenous echotexture of the prostate, with some hyperechoic area in the left side of the inner gland s/o chronic prostatitis. The patient was a young man with history of chronic dysuria and lower abdominal pain.
On sagittal section, the structures can be traced anteriorly and inferiorly.. definitely not the ureters.
Oblique transverse sections show the vessels communicating with their counterpart from the other side. Obviously these are vessels, most likely to be the periprostatic venous plexus.
Diagnosis: prostatitis with dilatated periprostatic veins.
