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.
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.
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).
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.
通过多排螺旋计算机断层扫描（MDCT）血管造影确定肾动脉测量的参考范围，并找出肾动脉测量值与动脉侧别、性别和年龄之间的关联。
纳入2016年11月至2017年4月期间就诊于卡拉奇齐亚丁医院放射科的250名无肾动脉疾病的研究参与者。在多排螺旋计算机血管造影上进行主要肾动脉测量，并分析其与侧别、性别和年龄的差异。使用社会科学统计软件包（SPSS）20版进行统计分析。应用独立样本t检验、单因素方差分析和Pearson相关分析。P值<0.05被认为具有统计学意义。
右肾动脉（直径6.66±0.39mm；长度44.69±2.48mm）与左肾动脉（直径6.79±0.36；长度35.10±2.86mm）之间存在显著差异（p=0.001）。发现女性肾动脉的平均直径和长度比男性小。然而，肾动脉平均直径与年龄之间存在弱负相关（右侧r=-0.158，p=0.0121；左侧r=-0.017，p=0.708）。
右、左主肾动脉之间以及男性和女性之间的平均直径和平均长度存在显著差异。肾动脉直径与年龄之间存在显著的弱负相关。
