What is the apex of the prostate?
Ultimately, the apex is the lower 1/3rd of the prostate gland, the midprostate is the middle 1/3rd of the prostate gland which includes the verumontanum in the midprostatic urethra, and the base is the upper 1/3rd of the prostate just below the urinary bladder (Figures 2 and 3).
Where does the prostatic artery originate from?
The prostate artery arises from the anterior division of the IIA in a common vesicoprostatic trunk with the superior vesical artery (SVA). Prostate artery origin from an aberrant obturator artery, which arises from the external iliac artery (EIA).
Where is the apex of the prostate gland located?
The apex is located at the inferior aspect of the organ. Its inferior relations include the bulbourethral (Cowper’s) glands, the external urethral sphincter muscles, and the retroprostatic part of the rectovesical space.
What does the inferior vesical artery supply?
Supplying the lower portion of the bladder, the inferior vesical artery is located in the pelvis. It is a branch of the anterior division of the internal iliac artery. Blood from this artery is delivered to the fundus (base) of the bladder.
How many arteries does the prostate have?
There is only 1 prostatic artery (2) arising from the internal pudendal artery (1). Inferior gluteal artery (3).
What zone of the prostate is affected in BPH?
The transition zone is a balloon-shaped component of the prostate that is located in the periurethral region. Most prostatic adenocarcinomas develop in the peripheral zone, although some arise in the transition zone. The transition zone is the exclusive site of benign prostatic hyperplasia (BPH).
What does inferior vesical artery supply in males?
In males, the main function of the inferior vesical artery is to supply blood for the fundus and neck of the male urinary bladder, prostate, seminal vesicles, vas deferens, urethra and ureter. In females, when present, it supplies the urinary bladder.
What arteries supply the prostate?
The inferior vesical artery is the major blood supply for the prostate, and it also receives blood supply from the middle rectal and internal pudendal arteries. Veins around the prostate form the prostatic plexus which drains into internal iliac veins.
Which lobe of the prostate is usually involved in BPH?
Conclusion. An enlarged median lobe is important in the setting of BPH and should be considered in treatment planning.
