The ureters receive arterial branches from adjacent vessels as they pass toward the bladder (Fig. 4.155):
The renal arteries supply the upper end.
The middle part may receive branches from the abdominal aorta, the testicular or ovarian arteries, and the common iliac arteries.
In the pelvic cavity, the ureters are supplied by one or more arteries from branches of the internal iliac arteries.
