Measurement of Renal Arteries Using Multi detector Computed Tomography: A Study in Tertiary Care Hospital in Nepal

Abstract

Introduction: The purpose of this study was to determine the dimensions of the renal arteries (length and diameter), among the patients referred for Contrast Enhanced CT(CECT) of abdomen in department of Radiology and Imaging, Tribhuwan University, Teaching Hospital.

Methods: This prospective study was performed in Department of Radiology and Imaging TUTH with A total of 135 (73 male and 62 female) patients underwent CECT abdomen from June to September 2018. In this study the diameter of right and left renal arteries, the length of right and left renal arteries were determined.

Results: The mean values of right renal artery diameter were found to be (0 .5706 ± 0.09861 cm) in males and (0.5061 ± 0.08384 cm) in females respectively. The mean values of left renal arteries diameter were found to be (0.5889 ± 0.10351 cm) in males and (0.5354 ± 0.10552 cm) in females respectively. The mean values of right renal artery length were found to be (4.568751 ± 0.83128cm) in males and (4.0318 ± 0.87575cm) in females respectively. The mean values of left renal arteries length were found to be (3.5990 ± 0.79567cm) in males and (3.2002 ± 0.59207cm) in females respectively. The diameter of renal artery diameter exhibited statistically significant differences in relation to age of the patients (p<0.05) with peak values in 55- 64 years age group where the mean right and left renal arteries diameters were found to be 5.801 mm and 6.012 mm respectively.

Conclusion: This study concluded that the diameter of the renal arteries varies significantly with the age of the patients.
