Introduction: The kidney is a retroperitoneal organ that weight from 125 to 170 g in the adult men and 115
to 155 g in adult women. Irrigation kidney is characterized by the presence of large anatomical variability that
may be influenced by ethnic and to a lesser extent by gender. Among the variations, there may be the presence
of an accessory renal artery that is projected into the upper or lower end of the kidney. This research aims
to observe the incidence of anatomical variations of the afferent renal artery and quantify both right and left
kidney weight. Materials and Methods: We analyzed kidney weights and accessory renal artery variations in
48 adult kidneys of both genders obtained from Institute of Anatomy of the University of Severino Sombra.
Subsequently, we compared the mean weights of kidneys in order to ascertain whether there was significant
discrepancy between the left and the right kidney. For this, we performed the Student t test considering a
P < 0.05. Results: The mean weight of the right kidney was 140.4 ± 22.6 g and the left was 148.8 ± 20.5 g.
In 40% of right kidneys was observed anatomic variation with the presence of accessory renal artery. To the left
kidney was observed a variation of 35%. Conclusion: We found that the accessory renal artery, when present,
was more closely related to the end of the kidney especially in the right kidney.
