The length of kidney plays important role in diagnosing chronic kidney diseases. Kidney length can be measured by ultrasound, a cheap, convenient and noninvasive method. There is no report on the length of kidney in healthy Thai people.
To measure the length of normal kidneys in Thai adults volunteers by ultrasonography.
Healthy volunteers were recruited and the study was performed from April 2008 to June 2009. All volunteers were examined by the same standard ultrasound machine and the same radiologist throughout the study period.
A total of 509 healthy volunteers were enrolled. The average lengths of left and right kidney were 10.24 +/- 0.70 and 10.09 +/- 0.68 cm, respectively. Male kidney was bigger than the female kidney. Kidney length slightly increased until the age of 50 and become smaller at the age of 60 or more. Kidney length showed no correlation with age, body weight, body mass index and body surface area.
The average lengths of left and right kidney were 10.24 +/- 0.70 and 10.09 +/- 0.68 cm, respectively. The length below 9.00 cm may indicate the state of kidney diseases.
肾脏长度在慢性肾脏病的诊断中起着重要作用。肾脏长度可通过超声测量，这是一种廉价、便捷且无创的方法。目前尚无关于泰国健康人群肾脏长度的报道。
通过超声检查测量泰国成年志愿者正常肾脏的长度。
招募健康志愿者，研究于2008年4月至2009年6月进行。在整个研究期间，所有志愿者均由同一台标准超声仪和同一位放射科医生进行检查。
共纳入509名健康志愿者。左、右肾的平均长度分别为10.24±0.70厘米和10.09±0.68厘米。男性的肾脏比女性的大。肾脏长度在50岁之前略有增加，60岁及以上则变小。肾脏长度与年龄、体重、体重指数和体表面积均无相关性。
左、右肾的平均长度分别为10.24±0.70厘米和10.09±0.68厘米。长度低于9.00厘米可能提示肾脏疾病状态。
