Excerpt:
"The prostate gland is the male organ most commonly afflicted
with either benign or malignant neoplasms. It comprises the most
proximal aspect of the urethra. Anatomically it resides in the true
pelvis, separated from the pubic symphysis anteriorly by the retropubic
space (space of Retzius). The posterior surface of the prostate
is separated from the rectal ampulla by Denonvilliers' fascia.
The base of the prostate is continuous with the bladder neck, and
the apex of the prostate rests on the upper surface of the urogenital
diaphragm. Laterally, the prostate is related to the levator ani
musculature. Its arterial blood supply is derived from branches
of the internal iliac artery (inferior vesical and middle rectal
arteries). Venous drainage is via the dorsal venous complex, which
receives the deep dorsal vein of the penis and vesical branches
before draining into the internal iliac veins. Innervation is from
the pelvic plexus. The normal prostate measures 3–4 cm
at the base, 4–6 cm in cephalocaudad, and 2–3
cm in anteroposterior dimensions. ..."
