Presentation Transcript
slide3

Objectives:

  • Discuss the site, size, shape and relation of prostate.
  • Describe the fasciae covering and related to the prostate (true and false capsules).
  • Discuss its blood, nerve supply and lymphatic drainage.
  • Define the seminal vesicles.
  • Discuss their site, relation, blood supply, venous drainage, lymphatic drainage & innervation.
  • Define the ejaculatory duct.
  • Describe its site, beginning and termination.

Prostate:

  • The prostate is a fibromuscular glandular organ that surrounds the prostatic urethra .
  • The prostate 3 cm long, 4 cm wide.
  • Lies between the neck of the bladder above and the urogenital diaphragm below.
  • Surrounded by a fibrous capsule.
slide6

Has a base, which lies against the bladder neck

  • An apex, which lies against the urogenital diaphragm.
  • Ejaculatory ducts pierce the posterior surface.
slide7

Relations:

  • Superiorly: neck of the bladder.
  • Inferiorly: the urogenital diaphragm.
  • Anteriorly: the symphysis pubis.
  • Posteriorly: the rectal ampulla.
  • Laterally: The prostate is embraced by the anterior fibers of the levatorani.
slide8

Structure of the Prostate

  • The prostate is incompletely divided into five lobes :
  • The anterior lobe lies in front of the urethra.
  • The median, or middle, lobe is the wedge of gland situated between the urethra and the ejaculatory ducts.
  • The posterior lobe is situated behind the urethra and below the ejaculatory ducts.
  • The right and left lateral lobes lie on either side of the urethra.
slide9

Blood Supply

  • Arteries:
  • Branches of the inferior vesicaland middle rectal arteries.
  • Veins
  • The veins form the prostatic venous plexus, which lies outside the capsule of the prostate.
  • The prostatic plexus receives the deep dorsal vein of the penis and numerous vesical veins and drains into the internal iliac veins.
slide11

Lymph Drainage

  • Internal iliac nodes.
  • Nerve Supply
  • Inferior hypogastric plexuses.
  • The sympathetic nerves stimulate the smooth muscle of the prostate during ejaculation.
slide12

Prostatic Urethra

  • The prostatic urethra is about 1.25 in. (3 cm) long and begins at the neck of the bladder.
  • The prostatic urethra is the widest and most dilatable portion of the entire urethra.
  • On the posterior wall is a longitudinal ridge called the urethral crest.
slide13

On each side of the urethral crest is a groove called the prostatic sinus.

  • Prostatic glands open into these grooves.
  • On the summit of the urethral crest is a depression, the prostatic utricle, which is an analog of the uterus and vagina in females.
  • On the edge of the mouth of the utricle are the openings of the two ejaculatory ducts.
slide14

Seminal Vesicles

  • The seminal vesicles are two lobulated organs about 2 in.(5 cm) long lying on the posterior surface of the bladder.
  • Each seminal vesicle consists of a much-coiled tube embedded in connective tissue.
slide15

Relations:

  • On the medial side of each vesicle lies the terminal part of the vas deferens.
  • Posteriorly, the seminal vesicles are related to the rectum.
  • Inferiorly, each seminal vesicle narrows and joins the vas deferens of the same side to form the ejaculatory duct.
slide16

Blood Supply:

  • Arteries
  • The inferior vesicle and middle rectal arteries.

Veins:

  • The veins drain into the internal iliac veins.

Lymph Drainage:

  • The internal iliac nodes.
slide17

Ejaculatory Ducts

  • The two ejaculatory ducts are each less than 1 in. (2.5 cm) long and are formed by the union of the vas deferens and the duct of the seminal vesicle.
  • The ejaculatory ducts pierce the posterior surface of the prostate and open into the prostatic part of the urethra, close to the margins of the prostatic utricle.
