ANATOMY
The prostate is the shape of an inverted pyramid and lies between the urinary
bladder and the pelvic floor. The base is the superior surface and lies at the
bladder neck, the anterior border forms the posterior wall of the retropubic
space and is attached to the pubic bones by the puboprostatic ligaments.
The posterior surface is anterior to the rectum and the inferolateral surfaces are
surrounded by the pubo-prostaticus fibers of the levator ani muscle. The
ejaculatory ducts pass through the posterior surface just inferior to the bladder
and open into the prostatic urethra about halfway along its length. It is a
fibromuscular and glandular organ that surrounds the prostatic urethra, the fibro-
muscular element being in direct continuity with the detrusor muscle of the
bladder. The true capsule of the prostate is a thin layer of connective tissue at
the periphery of the gland. This is surrounded by a condensation of pelvic
fascia known as the false capsule. The main blood supply is from the prostatic
branch of the inferior vesical artery. The venous drainage is via a plexus
between the two capsules. Lymph vessels drain to the internal iliac nodes.
