Introduction: The renal arteries are lateral branches of abdominal aorta which divide into segmental branches to supply a segment of the kidney. Accessory renal arteries have been commonly reported in literature. The arterial branching pattern is very much varied.
Materials and Methods: The study was conducted in 30 pairs of formalin fixed human cadaveric kidneys with intact renal artery and renal veins removed along with a part of abdominal aorta and IVC. The presence of accessory renal arteries, branching pattern of renal arteries, and length and width of renal arteries were noted.
Results: Accessory renal arteries were noted in 3 kidneys (5%). One left kidney was supplied by 3 renal arteries arising from the abdominal aorta. A pair of kidneys was supplied by 2 renal arteries arising from the abdominal aorta on either side. The mean length and width of right renal artery was 37.5 + 3.44mm and 6.51 + 1.26mm respectively. The mean length and width of left renal artery was 28.4 + 2.36mm and 6.24 + 1.36mm respectively. P1 branching pattern was observed in 38.3% of the specimens, L1 pattern in 23.33% of the specimens, A1 pattern in 26.66% of the specimens, U1 pattern in 10% of the specimens and triple pattern in 1.66% of the specimens.
Discussion: The mean length and width of renal arteries of the present study were similar to the results obtained in previous studies. Accessory renal arteries are end arteries and supply a particular segment of the kidney. So the knowledge of accessory renal arteries is important. The results of the branching pattern of renal arteries were compared with the results of Fine and keen’s study.
Conclusion: The knowledge of the presence of accessory renal arteries, dimensions and branching pattern of renal arteries will be helpful for urologist during renal surgeries.
