Reference charts depicting normal growth are important for the sonographic assessment of the pediatric kidney. Limited charts are available for clinical use in an Australian population.
To retrospectively collate sonographic renal length measurements in a cohort of low-risk Australian children aged newborn to 16 years to produce a reference table and comparison with other published charts.
We identified consecutive pediatric patients who were at low risk for renal disease and had renal lengths measured. After exclusions, we included 941 renal lengths (male 490, female 451). We used linear regression to estimate the relationship of renal length with age, gender and side. We calculated percentile values of renal length according to age categories.
No statistically significant differences in mean renal length were observed between males and females, or for left and right kidneys. We tabulated reference data and provide them in a reference chart (1-, 2.5-, 5-, 10-, 50-, 90-, 97.5- and 99-percentiles).
We calculated new reference ranges for pediatric renal length using a larger cohort than previously published, from a population with diverse ethnicity.
描绘正常生长的参考图表对于儿科肾脏的超声评估非常重要。在澳大利亚人群中，可供临床使用的图表有限。
回顾性地整理低危澳大利亚儿童（年龄从新生儿到 16 岁）的超声肾长度测量值，生成参考表，并与其他已发表的图表进行比较。
我们确定了连续的儿科患者，这些患者患有肾脏疾病的风险较低，并且进行了肾长度测量。排除后，我们纳入了 941 个肾长度（男性 490 个，女性 451 个）。我们使用线性回归来估计肾长度与年龄、性别和侧别之间的关系。我们根据年龄类别计算了肾长度的百分位数值。
男性和女性之间、左肾和右肾之间的平均肾长度没有统计学差异。我们列出了参考数据，并在参考图表中提供（1%、2.5%、5%、10%、50%、90%、97.5%和 99%的百分位数）。
我们使用比以前发表的更大的队列，从一个种族多样化的人群中计算出了新的儿科肾长度参考范围。
