    The aim of present study was to find the variations in the level of origin of renal arteries in relation to vertebrae and diameter by computed tomography. The scan films of abdomen of 300 patients were examined. The body of vertebra was divided into three parts, upper 1/3rd, middle 1/3rd and lower 1/3rd. The inter-vertebral disc was also considered. Each artery was divided into four types (Type I to Type IV) depending on the level of origin. Statistical analysis of data was done. The most common origin of Right Renal Artery was at L2 vertebra (2nd lumbar vertebra) in 61.33% of cases and L2 Type III was most common. The variations were observed in 38.67% of cases. The Left Renal Artery had shown most common origin at L2 vertebra in 61.67% of cases and L2 Type II was most frequent. The variations were observed in 38.33% of cases. The mean diameter of Right Renal Artery and Left Renal Artery was 6.04 mm and 5.90 mm respectively. The correlation of diameter of Right Renal Artery and Left Renal Artery was calculated with Pearson correlation coefficient which was significant with p-value <0.05. Accessory Renal Arteries were observed in 5.6% of cases. The diameter of main Renal Artery with Accessory Renal Artery was smaller than diameter of the main Renal Artery without Accessory Renal Artery. It was concluded that knowledge of variations in the Renal Arteries can be useful in renal transplantation and other surgical procedures of kidneys.
