中国0~14岁男童睾丸体积的超声测量研究

Ultrasound measurement of the testis volume of 0-14 years old Chinese boys

目的:为了获得中国男童从出生到14岁的超声测量的睾丸体积的正常参考值范围。方法:收集我院门诊或住院行睾丸超声检查的睾丸正常的0~14岁的男童,按年龄分成14组,每组不少于100例,行超声测量,计算各年龄组的睾丸体积的均数、标准差及中位数。结果:共测量1607例,得到各组的睾丸体积的平均值及标准差、中位数。0~8岁睾丸体积增大缓慢(0.372~0.678 ml),9岁以后睾丸开始加速增长(1.040~4.600 ml)。9~10岁、10~11岁、11~12岁、12~13岁、13~14岁的睾丸体积分别为(1.040±0.970)ml、(1.876±1.631)ml、(2.831±2.155)ml、(3.640±2.376)ml、(4.600±3.559)ml。但是,0~1岁组的睾丸体积比1~2岁体积大(0.403±0.130 ml vs 0.372±0.110 ml,P=0.04),与年龄呈负相关。结论:超声是一种有效的测量睾丸体积的方法,为0~14岁的中国男童提供了睾丸体积的正常参考值,可用于指导临床诊疗和咨询。

Objective:To obtain the normative values of the testis volume of 0-14 years old Chinese boys by ultrasound measurement.Methods:We collected the testicular ultrasound data on 1607 Chinese boys with normal testes between January 2016 and June 2019.The boys were aged 0-14 years and divided into 14 age groups,with at least 100 cases in each group.We compared the mean,standard deviation and median of the testis volume among different age groups.Results:The testis grew slowly in volume before 8 years old(0.372-0.678 ml),faster after 9 years old(1.040-4.600 ml),(1.040±0.970)ml at 9-10 years,(1.876±1.631)ml at 10-11 years,(2.831±2.155)ml at 11-12 years,(3.640±2.376)ml at 12-13 years,and(4.600±3.559)ml at 13-14 years,larger in the 0-1 than in the 1-2 years group([0.403±0.130]vs[0.372±0.110]ml,P=0.04),negatively correlated in age between the two groups.Conclusion:Ultrasonography is an effective method for the measurement of the testis volume,which can provide the normative values of the testis volume of the 0-14 years old Chinese boys and some evidence for clinical diagnosis and consultation.
