Prostate Zonal Anatomy

Benign prostatic hyperplasia is a reason for a dramatic increase. The prostate gland is composed of different types of tissue divided into zones.

The central zone constitutes 25 of the glandular prostate.

Prostate zonal anatomy. Transition zone surrounds the prostatic urethra. The central zone originates probably from the wolffian duct. The peripheral zone pz contains the majority of prostatic glandular tissue.

Small bph nodule at r base at the centralperipheral zone border benign prostate hyperplasia bph typically arises in the transition zone distorts zonal anatomy and can get very large over 200 ml. Its ducts arise close to the ejaculatory duct orifices and follow these ducts proximally branching laterally near the prostate base. Zonal anatomy of the prostate transition zone.

Prostate hyperplasia bph less commonly occurs outside of the transition zone. This zone enlarges in aging men resulting in benign prostatic hyperplasia. The central zone constitutes 25 of the glandular prostate.

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. Superiorly located portion of the prostate containing 25 of the prostatic glandular tissue. The largest area of the peripheral zone is at the back of the gland closest to the rectal wall.

Prostate zone anatomy prostate cancer and imaging. Ejaculatroy ducts pass through this zone from the seminal vesicles to the urethra prostate zonal anatomy mcneal click card to see definition. The central zone forms part of the base of the prostate and it is traversed by the ejaculatory ducts.

Its lateral border fuses with the proximal peripheral zone border completing in continuity with the peripheral zone. Mr imaging of the prostate gland. Its ducts arise close to the ejaculatory duct orifices and follow these ducts proximally branching laterally near the prostate base.

Scroll through the images to see the zones in which the prostate is divided. Central zone lies in the base of the prostate behind the transition zone and surrounds the left and the right ejaculatory duct. The peripheral zone showed higher signal intensity than either the central or transition zone.

Evaluating sequential sections the peripheral central and transition zones could be differentiated. The zonal anatomy of the prostate. Zonal anatomy of the normal prostate as described by mcneal 8 9 10.

The display of zonal anatomy was improved when continuous 05 cm slices were used. The prostate is comprised of three distinct zones with different embryologic origins. Its ducts arise close to the ejaculatory duct orifices and follow these ducts proximally branching laterally near the prostate base.

The anterior fibromuscular stroma 5 of the prostate. The transition zone comprises only 510 of the glandular tissue in the young male. The peripheral zone surrounds the distal prostatic urethra at the apex of the prostate and extends posterolaterally to the base.
