Anatomical variations of the renal artery based on the surgeon's direct observation : A French perspective

INTRODUCTION: Renal arterial vasculature presents a great anatomical variation. A good knowledge of this anatomy is essential in the field of kidney transplantation. The aim of this study is to describe the anatomical variations of the renal arterial vasculature based on the retrieved but not transplanted kidneys (RNTK) and their contralateral grafted kidneys (CGK), which anatomy is described by surgeons themselves after aortic dissection during multi-organ procurement (MOP).
MATERIAL AND METHODS: Using the "Crystal" database of the French "Agence de la biomédecine" (ABM), all RNTK were retrospectively selected over one year. Then, the arterial anatomy of each RNTK and their CGK was studied using the surgical and the histopathological reports. The surgical report was completed by the surgeon at the end of the MOP from deceased donors. The qualitative variables were expressed in numbers (percentage of the population) and were compared by a Chi2 test or an exact Fisher test depending on the sample size. A P-value of less than 0.05 was considered statistically significant.
RESULTS: In total, 356 kidneys were studied (241 RNTK - 115 CGK), 69% had a single artery and 31% had multiple arteries (26% with two arteries and 5% with three or more). The incidence of multiple arteries was similar between the right and left kidneys (32% vs. 30% respectively). A modal arrangement with 1 artery on each side was present in 51% of cases. Thus, 1 in 2 donors had at least 2 arteries on one side. Multiple arteries were bilateral in 12% of cases. The RNTK group presented more kidneys with multiple arteries than the CGK group (35% vs. 22%).
CONCLUSION: Our study shows a higher incidence of multiple renal arteries than the literature (31% vs. 25%). Thus, MOP can be considered as an accurate and reliable method of describing renal arterial anatomy, especially that some small arteries may be missed when using radiological or cadaveric dissection techniques.
