To determine normal ranges for pediatric testicular volume and stiffness values (SV) on ultrasonography (US) and shear wave elastography (SWE) with respect to age and weight, testicular US scans (including SWE) of children (<10 y old) performed from February 2015 to January 2017 were retrospectively reviewed; grossly normal testes or testes with small hydroceles were included. Correlations between age weight, and testicular volume or SV were evaluated. Among a total of 52 boys (1-92 mo, median = 23.5 mo), there were positive correlations between testicular volume and age (R = 0.451, p < 0.001) and weight (R = 0.515, p < 0.001). Testicular SV was negatively correlated with age (R = 0.166, p = 0.051) and weight (R = 0.372, p = 0.049). Therefore, SV decreases while volume increases with increasing weight in testes of healthy children. Normal ranges for testicular volume and SV in children younger than 10 y are reported.
为了确定儿科睾丸体积和（SV）超声弹性成像值的正常范围，对 2015 年 2 月至 2017 年 1 月期间进行的儿童（<10 岁）睾丸超声检查（包括 SWE）进行了回顾性研究；包括大体正常的睾丸或有小鞘膜积液的睾丸。评估了年龄、体重与睾丸体积或 SV 之间的相关性。在总共 52 名男孩（1-92 个月，中位数=23.5 个月）中，睾丸体积与年龄（R=0.451，p<0.001）和体重（R=0.515，p<0.001）呈正相关。睾丸 SV 与年龄（R=0.166，p=0.051）和体重（R=0.372，p=0.049）呈负相关。因此，健康儿童的睾丸中，SV 随着体重的增加而降低，而体积则随之增加。报告了年龄小于 10 岁的儿童睾丸体积和 SV 的正常范围。
