Renal length estimation by ultrasound is an important parameter in clinical evaluation of kidney disease and healthy donors. Changes in renal volume may be a sign of kidney disease. Correct interpretation of renal length requires the knowledge of normal limits, these have not been described for Latin American population.
To describe normal renal length (RL) by ultrasonography in a group of Mexican adults.
Ultrasound measure of RL in 153 healthy Mexican adults stratified by age. Describe the association of RL to several anthropometric variables.
A total of 77 males and 76 females were scanner. The average age for the group was 44.12 +/- 15.44 years. The mean weight, body mass index (BMI) and height were 68.87 +/- 11.69 Kg, 26.77 +/- 3.82 kg/m2 and 160 +/- 8.62 cm respectively. Dividing the population by gender, showed a height of 166 +/- 6.15 cm for males and 154.7 +/- 5.97 cm for females (p =0.000). Left renal length (LRL) in the whole group was 105.8 +/- 7.56 mm and right renal length (RRL) was 104.3 +/- 6.45 mm (p = 0.000.) The LRL for males was 107.16 +/- 6.97 mm and for females was 104.6 +/- 7.96 mm. The average RRL for males was 105.74 +/- 5.74 mm and for females 102.99 +/- 6.85 mm (p = 0.008.) We noted that RL decreased with age and the rate of decline accelerates alter 60 years of age. Both lengths correlated significantly and positively with weight, BMI and height.
The RL was significantly larger in males than in females in both kidneys (p = 0.036) in this Mexican population. Renal length declines after 60 years of age and specially after 70 years.
通过超声估计肾脏长度是评估肾脏疾病和健康供体的临床重要参数。肾脏体积的变化可能是肾脏疾病的一个迹象。正确解读肾脏长度需要了解正常范围，而拉丁美洲人群的正常范围尚未有描述。
描述一组墨西哥成年人通过超声测量的正常肾脏长度（RL）。
对153名健康墨西哥成年人按年龄分层进行肾脏长度的超声测量。描述肾脏长度与多个人体测量变量之间的关联。
共扫描了77名男性和76名女性。该组的平均年龄为44.12±15.44岁。平均体重、体重指数（BMI）和身高分别为68.87±11.69千克、26.77±3.82千克/平方米和160±8.62厘米。按性别划分人群，男性身高为166±6.15厘米，女性身高为154.7±5.97厘米（p = 0.000）。整个组的左肾长度（LRL）为105.8±7.56毫米，右肾长度（RRL）为104.3±6.45毫米（p = 0.000）。男性的LRL为107.16±6.97毫米，女性为104.6±7.96毫米。男性的平均RRL为105.74±5.74毫米，女性为102.99±6.85毫米（p = 0.008）。我们注意到肾脏长度随年龄下降，60岁以后下降速度加快。两个肾脏的长度均与体重、BMI和身高显著正相关。
在这个墨西哥人群中，两个肾脏的肾脏长度男性均显著大于女性（p = 0.036）。60岁以后肾脏长度下降，70岁以后尤为明显。
