Zonal Anatomy Of Prostate

It forms a disc of tissue whose ducts radiate laterally from the urethra lateral and distal to the verumontanum. Histologic variation by anatomic region apical one third of the prostate apex.

Zonal anatomy of prostate. Anatomy of the prostate gland in surgical pathology specimens. Almost all carcinomas arise here. The prostate is comprised of three distinct zones with different embryologic origins.

The central zone constitutes 25 of the glandular prostate. The largest area of the peripheral zone is at the back of the gland closest to the rectal wall. The peripheral zone surrounds the distal prostatic urethra at the apex of the prostate and extends posterolaterally to the base.

Prostate zone anatomy prostate cancer and imaging. The large cup shaped peripheral zone pz encompasses the central and transition zones and accounts for approximately 70 of the total prostate volume in a young adult. Zonal anatomy of the prostate transition zone.

The prostate gland is composed of different types of tissue divided into zones. These small ducts in a restricted area are the exclusive site of nodular hyperplasia bph origin. The anterior fibromuscular stroma 5 of the prostate.

Benign prostatic hyperplasia is a reason for a dramatic increase. Basal one third of the prostate base. The peripheral zone pz contains the majority of prostatic glandular tissue.

The anterior fibromuscular stroma forms the entire anterior surface of the prostate as a thick nonglandular apron shielding from view the anterior surface of the three glandular regions. The peripheral zone constitutes over 70 of the glandular prostate. Its ducts arise close to the ejaculatory duct orifices and follow these ducts proximally branching laterally near the prostate base.

The central zone originates probably from the wolffian duct. The zonal anatomy of the prostate.
