Prostate blood supply in addition to the other under the bladder arteries and other arterial blood supply.Refer to Chen’s autopsy of the prostate feeding artery report, prostate blood supply mainly from the inferior arteries (74.3%), the superior bladder artery (8.9%), The rectal artery (2.2%), the rectal artery (7.3%), the vas deferens (5.0%), and the obturator artery (1.7%). The branches of these arteries originate above the bladder prostatic junction and pass through the bladder Prostate gutter penetration into the prostate gland substance or down in the prostate capsule.According to the order of the clock in the bladder between the prostate gland ditch at each point of the artery, bladder artery, bladder artery, rectum, upper and lower arteries and vas deferens artery, closed Pituitary artery of the prostate branch at 12 o’clock, 1 to 4 (11 to 8) points, 4 (8) to 6 points, 1 to 2 (11 to 10) point at the prostate.
