Abstract
Objective:To determine a reference range of renal artery measurements by using Multidetector Computed Tomography (MDCT) angiography and to find association of renal artery measurements with side of artery, gender and age.Method:Two hundred and fifty study participants without renal artery disease who werepresented to Radiology Department, Ziauddin Hospital, Karachi, from November, 2016 to April, 2017 were included in this study. Main renal artery measurements were taken on Multidetector computed angiography and variation with side, gender and age were analyzed. Statistical analysis was done on Statistical Package for Social Sciences (SPSS) version 20. Independent sample T test, one way ANOVA and Pearson’s correlation analysis were applied. P-value of < 0.05 was considered significant.Results:A significance difference (p=0.001) was seen between mean right renal artery (diameter 6.66 ± 0.39 mm; length 44.69 ± 2.48 mm) and left renal artery (diameter 6.79 ± 0.36; length 35.10 ± 2.86 mm). Females found to have smaller mean diameter and length of renal arteries than males. However, a weak negative correlation was seen between mean renal artery diameter and age (right r= -0.158, p=0.0121; left r= -0.017, p= 0.708).Conclusion:The mean diameter and mean length were found to be significantly different between right and left main renal artery and between males and females. A significant weak negative correlation was observed between renal artery diameter and age.
Highlights
In South Asian country like Pakistan, incidence of end stage renal disease (ESRD) is gradually increasing and has produced a large economic burden.[1]
For end stage renal disease, renal transplant is considered as the best choice of treatment modality
Our results are in agreement with the results reported in a study conducted in Columbia, which reported right renal artery diameter to be significantly less than left renal artery diameter.[25]
Summary
In South Asian country like Pakistan, incidence of end stage renal disease (ESRD) is gradually increasing and has produced a large economic burden.[1] For end stage renal disease, renal transplant is considered as the best choice of treatment modality. It is essential, that each potential living donor should have a complete renal vasculature evaluation to avoid complications.[2] It is important for the surgeon to know the precise range of diameter, length and exact site of origin of renal arteries for accurate renal assessment.[3]. Studies have been performed in different parts of world to establish normal reference range of renal artery dimensions.[3,16,17] Review of literature showed that studies performed in our population were mainly in context with renal vascular pathologies as renal artery stenosis and renovascular hypertension.[18,19,20] this study was conducted to determine a reference range of normal renal artery measurements and to find its variation with side of artery, gender and age in our population by using MDCT angiography in our population
