Ultrasound (US) measurements of kidney dimensions are essential for correlating with height, weight, and body mass index (BMI), establishing kidney size baselines, and assessing renal health. The global rise in obesity has increased interest in the links between BMI and chronic kidney disease (CKD). This study investigates the relationship between renal dimensions (length, width, and thickness) and anthropometric measures (height, weight, and BMI) in a Saudi population.
A cross-sectional study was conducted at two ultrasound clinics in Riyadh, Saudi Arabia, with 129 participants (73 males and 56 females) aged 18-60 years. Kidney dimensions were measured using ultrasound machines. Spearman correlation assessed relationships between kidney dimensions and age, height, weight, and BMI, while the Mann-Whitney U test investigated sex differences.
Significant correlations were identified between kidney dimensions and anthropometric measures. Age negatively correlated with kidney thickness for both kidneys (right: = -0.502, < 0.0001; left: = -0.542, < 0.0001) and left kidney width ( = -0.204, = 0.020). Height positively correlated with all kidney dimensions. Weight also positively correlated with kidney dimensions. BMI showed positive correlations with right kidney length ( = 0.219, = 0.013) and width ( = 0.319, < 0.0001), and left kidney length ( = 0.209, = 0.018). Males had greater kidney thickness and left kidney width compared to females.
This study establishes significant correlations between renal dimensions and anthropometric measures in a Saudi population, highlighting the importance of considering individual characteristics in renal assessments. These findings support the development of personalized clinical guidelines for improved renal condition management.
超声（US）测量肾脏尺寸对于与身高、体重和体重指数（BMI）进行关联、建立肾脏大小基线以及评估肾脏健康至关重要。全球肥胖率的上升增加了人们对BMI与慢性肾脏病（CKD）之间联系的兴趣。本研究调查了沙特人群中肾脏尺寸（长度、宽度和厚度）与人体测量指标（身高、体重和BMI）之间的关系。
在沙特阿拉伯利雅得的两家超声诊所进行了一项横断面研究，共有129名年龄在18至60岁之间的参与者（73名男性和56名女性）。使用超声机器测量肾脏尺寸。Spearman相关性分析评估肾脏尺寸与年龄、身高、体重和BMI之间的关系，而Mann-Whitney U检验则研究性别差异。
确定了肾脏尺寸与人体测量指标之间存在显著相关性。年龄与双侧肾脏厚度呈负相关（右侧： = -0.502， < 0.0001；左侧： = -0.542， < 0.0001），与左肾宽度呈负相关（ = -0.204， = 0.020）。身高与所有肾脏尺寸呈正相关。体重也与肾脏尺寸呈正相关。BMI与右肾长度（ = 0.219， = 0.013）和宽度（ = 0.319， < 0.0001）以及左肾长度（ = 0.209， = 0.018）呈正相关。男性的肾脏厚度和左肾宽度大于女性。
本研究在沙特人群中建立了肾脏尺寸与人体测量指标之间的显著相关性，突出了在肾脏评估中考虑个体特征的重要性。这些发现支持制定个性化临床指南以改善肾脏疾病管理。
