“…This phenomenon is mainly due to embryonic ascent of the kidney. 11,12 In our series the rate of supernumerary arteries were 27.3% and 31% in arteries of the right and left kidneys respectively, according to the MDCTA. These rates were in accordance with other series carried out either in cadaver or imaging series.…”

“…In only 1.4% of kidneys there were three arteries. Variations among males were more than females (27.2% vs. 15.2%) [33]. It was described that 64.3% of the patients with renal artery variation also had hepatic artery and/or coeliac trunk variation.…”

Concomitant multiple anomalies of renal vessels and collecting system

Although anomalies of renal vessels and collecting system are relatively frequent, their concomitant occurrence is a rare event. During dissection of a 75-year-old male formalinembalmed cadaver, we found multiple variations in the renal vessels and renal collecting system. Both kidneys were normal in size and anteriorly malrotated, with duplex collecting system and duplex ureter. One ureter drained the upper part of the kidney and the second ureter drained the lower part of the kidney. Superior and inferior collecting systems were separated by renal parenchyma. The right kidney had two renal arteries, the first renal artery (main renal artery) originating from the abdominal aorta, passing behind the inferior vena cava and entering the kidney through the superior and inferior renal hilum. The second artery was the inferior polar artery. In addition, the right kidney had two renal veins as well. Three renal tributaries emerged from the upper and lower portion of the right renal hilum, and they joined to form the main renal vein which drained into the inferior vena cava. The lower renal vein was the inferior polar vein. The left kidney had four renal arteries (two hilar arteries and two polar arteries). The main left renal vein emerged from both superior and inferior left renal hilum, passed in front of the abdominal aorta and drained into the inferior vena cava. The left kidney also had the inferior polar vein which was divided behind the aorta (retro aortic vein) into two venous trunks. These venous trunks drained separately into posteromedial aspect of the inferior vena cava. Finally, the right testicular vein was formed by two tributaries and drained into the inferior vena cava, whereas the two left testicular veins drained separately into the left main renal vein.

“…Arterial branching from the iliac axis has also been documented, particularly in ectopic kidneys [15–17], however ectopic specimens without pelvic involvement have also demonstrated branches arising from the iliac region [14, 18]. Bilateral variation in the arterial patterning has been quantified with an incidence of approximately 10% [19] while unilateral arterial supply to the kidney arising from all of these regions has a suggested incidence of approximately 0.4% [20, 21].…”

Variations in the arterial, venous, and ureteral patterning of the right (r) and left (l) kidneys are common; however, concomitant involvement with all three systems is rare. Specimens that demonstrate anatomic variation across multiple systems provide an opportunity to illustrate links between anatomic concepts, embryologic development, clinical practice, and education. During anatomic study of the abdominal cavity, a total of five major arteries (3l and 2r) emerged from the aortic and common iliac axes in a cadaveric donor. Through continued study, multiple contributing veins, of different caliber, coalesced into four major renal veins (2l and 2r) that returned blood from the kidneys to the inferior vena cava (IVC) at different locations. In addition, unilateral duplication of the kidney with concomitant ureters was evident on the right side. Both ureters continued inferiorly and independently entered the bladder, each with an observable orifice adjacent to the bladder trigone. Most evident in the specimen was the anteriorly directed hilum for both kidneys. Reported measures for each of the observed anatomic variations suggest that the current specimen has an estimated incidence of less than 0.3%. This comparatively rare specimen provides an example of important anatomic concepts that are relevant to educational and clinical practices.
