To determine renal volume in adult patients with essential hypertension and correlate it with age, sex, body mass index (BMI), body surface area (BSA) and duration of hypertension.
A total of 150 patients (75 males, 75 females) with essential hypertension and normal renal status were evaluated sonographically in this prospective study. Fifty healthy individuals (25 males, 25 females) without hypertension were also evaluated as control. Renal volume was then calculated from the kidney's length, width and anterio-posterior diameter using the formula L×W×AP×0.523.
The range of renal volume obtained was 51.65-205.02 cm(3), with a mean of 114.06 ± 29.78 cm(3) for the left kidney and 47.37-177.50 cm(3) with a mean of 106.14 ± 25.42 cm(3) for the right kidney. The mean volumes of the right and left kidneys in males (112.98 ± 25.56 cm(3) and 123.11 ± 32.49 cm(3), respectively), were significantly higher than in females (99.31 ± 23.07 cm(3) and 105.01 ± 23.77 cm(3), respectively). Renal volume correlated significantly with BSA and BMI, but decreased with age. The renal volume showed no correlation with duration of hypertension.
Renal volume is higher in the left than the right kidney in hypertensive patients of both sexes and female hypertensive patients have smaller kidney size compared to males. The study also shows that volume of both kidneys decreases with age and positive correlation between renal volume, BSA and BMI. However, there is no correlation between renal size and duration of hypertension.
本研究旨在确定原发性高血压成年患者的肾脏体积，并与年龄、性别、体重指数（BMI）、体表面积（BSA）和高血压病程进行相关性分析。
本前瞻性研究共纳入 150 例原发性高血压且肾功能正常的患者（75 例男性，75 例女性），并对其进行超声检查。同时纳入 50 例无高血压的健康个体（25 例男性，25 例女性）作为对照组。肾脏体积通过肾脏的长、宽和前后径，使用公式 L×W×AP×0.523 进行计算。
获得的肾脏体积范围为 51.65-205.02 cm³，左肾平均体积为 114.06 ± 29.78 cm³，右肾平均体积为 47.37-177.50 cm³。男性的右肾和左肾平均体积（112.98 ± 25.56 cm³和 123.11 ± 32.49 cm³）明显高于女性（99.31 ± 23.07 cm³和 105.01 ± 23.77 cm³）。肾脏体积与 BSA 和 BMI 显著相关，但与年龄呈负相关。肾脏体积与高血压病程无相关性。
在男女高血压患者中，左肾的体积大于右肾，且女性高血压患者的肾脏体积小于男性。研究还表明，双侧肾脏的体积随年龄的增长而减小，且肾脏体积与 BSA 和 BMI 呈正相关。然而，肾脏大小与高血压病程无相关性。
