A sonographic study of 49 randomly selected healthy adult Jamaicans was conducted to establish a guide for renal dimensions in the population. The mean length of the right kidney was 9.7 +/- 0.7 cm and the left 10 +/- 0.7 cm. The left kidney was longer than the right in the overall group and in males. There was no difference in width between right or left kidneys in the group as a whole or within either gender. There was a significant association between the weight of males and width of their kidneys; however, this association was not seen in females. The lone association between weight of participants and renal length occurred in females and only with respect to the left kidney. Lengths and widths of kidneys were not associated with height in either gender. Renal surface area (RSA) was similar between the genders and also between right and left kidneys. Similarly, there was no significant association between renal length and body surface area (BSA) overall or within the genders. Renal index (RI) which is more reliable at assessing renal parenchymal mass than renal length alone was 20.92 and 22.86 for the right and left kidneys, respectively, in males. Similarly, RI for the right and left kidneys in females was 23.76 and 25.54, respectively.
对49名随机选取的牙买加健康成年人进行了超声检查研究，以建立该人群肾脏尺寸的参考标准。右肾平均长度为9.7±0.7厘米，左肾为10±0.7厘米。在整个研究组以及男性中，左肾比右肾长。在整个研究组或任何一个性别中，左右肾的宽度没有差异。男性体重与肾脏宽度之间存在显著关联；然而，在女性中未观察到这种关联。参与者体重与肾脏长度之间唯一的关联出现在女性中，且仅与左肾有关。无论男性还是女性，肾脏的长度和宽度与身高均无关联。两性之间以及左右肾之间的肾表面积（RSA）相似。同样，总体上或在两性中，肾长度与体表面积（BSA）之间均无显著关联。在评估肾实质质量方面比单独的肾长度更可靠的肾指数（RI），男性右肾和左肾分别为20.92和22.86。同样，女性右肾和左肾的RI分别为23.76和25.54。
