Introduction: Variability in renal vascularization occurs with a frequency of around 30%. During the routine dissection of one cadaver without renal pathology, we revealed the presence of one. Material and Methods: Dissection of a cadaver carried out in the practicing room of School of Medicine. Results: During the routine dissection of one cadaver without renal pathology, we revealed the presence of an early bifurcation of the renal artery on the left side, and the presence of two polar arteries – superior and inferior -, the latter presenting an anterior and posterior vascular arch to the renal pelvis in the parenchyma, which anastomoses the pre- and retro-pyelic branches of the renal artery with the pre- and retro-pyelic branches of the inferior accessory polar artery. In addition, the presence of an accessory polar artery was observed in the right kidney. Discussion and Conclusion: For vascular surgeons, knowledge of this anatomical variation is of real clinical relevance in cases such as fenestrated endografting in order to preserve the function of the entire kidney.
