[The urogenital artery of the adult dog]

For this study 52 formaldehyde-fixed pelvis from both sexes dogs (Canis familiaris), unknown races and different ages, injected with latex through the aorta, were used. The results were classified in common (A) and uncommon (B, B1, B2 and B3) modalities: A-44 dogs (84.62%; 74.82-94.42%), with emergence of the urogenital artery from the visceral branch of the hypogastric artery; B-5 dogs (9.62%; 2.70-22.10%), where the vessel arises from the umbilical artery. In this manner, the intrapelvic organs (ureter, deferent duct, bladder, prostate and urethra in male, and ureter, bladder, urethra, uterus and vagina in female) are supplied with blood through the urogenital and umbilical arteries, and urethral branch, as well as the cranial and ventral vesical arteries to the bladder.
