A study of evaluation of renal artery measurements using computed tomography angiography in adult Aswanian population

Abstract

Background: Morphometric studies are important as they increase our knowledge of anatomical relationships and facilitate treatment planning and device development. Aim of Study: to determine a reference range of renal artery measurements by using MDCT angiography and to find association of renal artery measurements with side of artery and gender in Aswanian population. Patients and Methods: The study includes 106 patients who underwent abdominal MDCT angiography. Images were evaluated for the level of origin, length, diameter, gender& side variations of renal arteries. Results: the most frequent level of origin of the renal arteries was lower third of L1, followed by disc between L1-L2. The diameter of main renal artery was (4.83±0.88 on right side& 5.04±0.82 on left side), the renal artery diameter in males was wider than females (pvalue = 0.022). The length of the right renal artery was (3.57±1.07) longer than the left (2.87±0.83). The diameter of the main renal artery in kidney with single renal artery was wider than kidneys having multiple renal arteries (p-value < 0.000). Conclusion: The renal arteries present a broad spectrum of variability in their morphological expression respecting their length, level of ramification, diameter and emergence.
