The prostate gland is part of the male reproductive system and is the largest prostata CT accessory gland. It typically weighs prostata CT grams with an average size of 3 x 4 x 2 cm. The prostate gland is an inverted pyramid that surrounds the proximal urethrawhich traverses the prostate close to its anterior surface.
It has a superior base, inferior apex and anterior, inferolateral and posterior surfaces. The base of the prostate is in continuity with the bladder. It ends prostata CT at the apex at the urogenital diaphragm The anterior surface forms the posterior limit of the retropubic space. The prostate is connected to the pubic bone by the puboprostatic ligaments 1.
Prostata CT inferolateral surface rests on the levator ani fascia 3. Its triangular and flat posterior surface is anterior to the rectum and has a vertical median groove, which is palpable via a digital rectal exam DRE. The seminal vesicles are superior and posterior to the prostate gland. Their ejaculatory ducts pierce the posterior surface of the prostate below the bladder and drain into the prostatic urethra. The prostate gland lacks a true capsule and the so-called prostate capsule is a pseudocapsule formed from fibromuscular tissue surrounding 3 distinct layers of fascia; the anterior, lateral, and posterior fasciae.
Anteriorly and apically this pseudocapsule is deficient. Laterally the fascia prostata CT with the levator fascia. Prostata CT prostatic venous plexus Santorini's plexus lies between and passes through, the pseudocapsule and fasciaNeurovascular bundles travel posterolaterally at 5 and 7 o'clock and give prostata CT branches into the prostate at the apex and base 5.
The peripheral zone surrounds the distal prostatic urethra at the apex of the prostata CT and extends posterolaterally to the base. Most prostatic tumors occur in the PZ. It is posterior to the prostatic urethra and forms the base of the prostate. It is predominantly anterolateral to the prostatic urethra The transition zone is occasionally written incorrectly as the transitional zone. Benign prostatic hypertrophy occurs in the TZ. Some radiologists and urologists refer to the central gland CG which consists of both the central and transition zones.
