(1) The urachal artery has a primary origin from the umbilical artery itself, and is at first bilateral. (2) The arterial pattern in newborn infants is not identical to that of adults. Obliteration of the umbilical artery in older infants carries with it obliteration of some of its branches, especially at their origin from its distal part, with a resulting change in arterial pattern. (3) The middle vesicle artery is a fairly constant branch of the umbilical artery, supplying the bladder neck and the front of the bladder above the neck. (4) The urachal and middle vesicle arteries, when unilateral, occur with equal frequency on both sides. (5) The anastomosis between superior vesical and inferior episgastric arteries was confirmed in the subperitoneal tissues, but was very rare in the wall of the bladder, occurring only when an abnormal obturator artery was the source of a superior vesical branch. (6) The constancy of the vesiculo-deferential artery is confirmed.
(1)脐尿管动脉主要起源于脐动脉本身，起初是双侧的。(2)新生儿的动脉模式与成年人不同。较大婴儿的脐动脉闭塞会导致其一些分支闭塞，尤其是在其远端起源处，从而导致动脉模式发生变化。(3)中膀胱动脉是脐动脉相当恒定的分支，供应膀胱颈及膀胱颈上方的膀胱前部。(4)脐尿管动脉和中膀胱动脉单侧出现时，两侧出现频率相等。(5)在腹膜下组织中证实了膀胱上动脉与腹壁下动脉之间的吻合，但在膀胱壁中非常罕见，仅在异常闭孔动脉是膀胱上分支的来源时才会出现。(6)证实了输精管膀胱动脉的恒定。
