OBJECTIVE: The aim of this retrospective study was to evaluate the relationship between renal artery morphometry and renal artery plaque formation and location using multislice computed tomography angiography images. METHODS: The study was conducted retrospectively using multislice computed tomography angiography data from a cohort of 130 patients. Specific measurements included abdominal aortic diameter, contrast material density, right and left renal artery diameters, lengths, angles of aortic separation, and their vertebral levels. Plaque locations in the renal artery and abdominal aorta were recorded. The statistical analysis utilized independent samples t-tests, analysis of variance, and Pearson's correlation. RESULTS: A moderate positive correlation (r=0.308, p<0.01) was found between plaque formation and abdominal aortic diameter. An abdominal aortic diameter of ≥20.5 mm was determined as a significant risk threshold for plaque formation in the renal artery (sensitivity: 0.69, specificity: 0.68). The mean arterial length with plaque was significantly longer than that without plaque (difference: 6.97 mm, p=0.029), a relationship that was particularly evident in the right renal artery. In women, a significant association was observed between plaque formation and increased renal artery diameter (difference: 2.10±0.67 mm, p=0.017) and increased renal artery separation angle (difference: 27.44±10.04°, p=0.042). In renal arteries with plaque, both abdominal aorta and renal artery density values were lower than those without plaque (p<0.01). CONCLUSION: Our findings suggest that the size of the abdominal aorta diameter and the length of the renal artery are important anatomical factors contributing to plaque formation in the renal artery.
