Anatomical Variations of Renal Artery in Patients Undergoing Computerized Tomographic Scan in Sudan

Abstract

Anatomical Variations of Renal Vascular in Patients Undergoing Computerized Tomographic scan in Sudan, the total number of patients studied is 400, 202 (50.5%) males and 198 (49.5%) females, and their ages ranged between (3 -94) years. The study showed mean of total samples of the width and length of right and left kidneys respectively measurements were 5.354 ± 0.948 and 5.571 ± 0.966 for width and 10.028 ± 1.3684 and 10.060 ± 1.5203 for length, the width and length for right renal artery 5.746 ± 1.2814 and 5.881 ± 1.1444 respectively and for left renal artery 5.894 ± 1.3175 and 4.961 ± 1.3175 respectively. Accessory renal artery is a common but a significant anatomical variant of the renal vascular system, due to its clinical importance. In our sample, the accessory renal artery presence was detected in 6% and displayed a greater variation on the right than the left side. Because this abnormality plays an important role in kidney transplantations, in radiological, vascular and urological interventions, a detailed presentation of accessory renal artery incidence was conducted, gathering from the literature a large number of relevant studies in order to create a classification according to population, gender, side and specimen. And the study concluded that the renal arteries present a broad spectrum of variability in their morphological expression regarding their length, diameter and entrance to the kidney parenchyma. The inferior polar renal artery was found same as the superior polar renal artery, additional arteries' morphological expression was higher in men than women. This is statistically not significant and variation in the right side was found greater frequency than the left side.
