“…These arteries in question should be named multiple arteries; the words "extra .... aberrant" and "accessory", frequently utilized, should be avoided, since these vessels are in fact normal segmental end-arteries, without anastomosis between them. Thus, these vessels correspond indeed to the segmental branches of a single renal artery [8,9,11]. Even the term "supernumerary" should not be used, as it might express that these vessels are superfluous.…”

The renal arterial supply was analyzed in 266 kidneys dissected from 133 fixed adults subjects. The anatomical findings are presented: 1 hilar artery in 53.3% of the cases, 1 hilar artery with 1 superior pole extra-hilar branch in 14.3%, 2 hilar arteries in 7.9%, 3 hilar arteries in 1.9%, superior polar artery in 6.8%, inferior polar artery in 5.3% and other variations in 8.5%. The urological and radiological implications of these findings in kidney transplantation, renovascular hypertension, renal trauma, interventional radiology, conservative surgery and oncologic surgery are discussed.

SUMMARY:Irrigation of the kidneys is usually provided by a single renal artery; however, variations on this pattern have frequently been reported. This study was aimed at establishing the renal arteries' frequency and morphological characteristics in cadaverous material taken from a half-caste population from Bucaramanga (Colombia). The sample included 195 renal blocks corresponding to 57 (14.6%) kidneys from females and 333 (85.4%) from males. The renal arteries were injected with synthetic resin (palatal GP41L); following the resin's polymerization, the renal blocks were placed in KOH solution for corrosion the renal parenchyma. The individuals from whom the renal blocks, 74.9% of the kidneys presented renal arteries single and 25.1% had additional renal arteries. Average right and left renal artery length was 34.6 mm and 28.6 respectively (p<0.001). Renal artery diameter was 4.87 mm. Main renal arterydiameter in kidneys presenting additional renal arteries was less than that of those having a single renal artery, this being a significant difference (p= 0.0000). The renal arteries more frequently (85%) originated from the anterolateral part of the aorta. The right renal artery emerged rostrally in 49.2%, whilst both arteries were located at the same level in 34.4%. The renal poles received a greater contribution from frontal division branches, the upper pole 46.4% and the lower pole 55.9%. No significant differences were presented in the characteristics studied here regarding gender. The renal arteries presented great variability in morphological expression regarding their emergence and ramification level.

“…Although many of these abnormalities have been described in isolation (Garti et al, 1986;Pendarvis et al, 1997;Yen et al, 2004;Zhou et al, 2007;Ng and Ng, 2009), they are all rare anomalies and for all of them to occur independently would be exceedingly rare. As such, we favor an explanation that provides a more unified hypothesis for the origin of these anomalies based on the current knowledge of the formation of the abdominal aorta in the early embryo.…”
