The purpose of this study was to determine the normal range of renal length in Hong Kong Chinese children and compare it with Western data.
Two hundred fifty children undergoing routine abdominal sonography were examined prospectively, and the maximum length of 1 kidney per child was recorded. Ages ranged from newborn to 19 years, and there were 109 girls and 141 boys. Similar data from Australian children involved maximum lengths of both kidneys in 554 children ranging in age from newborn to 14 years. There were 361 girls and 193 boys. No children had known renal disease.
There was no statistically significant difference between the mean renal lengths of girls and boys. Statistical comparison of the data from Hong Kong and Australia showed no significant difference except in the 8-12 month age group (this difference is unlikely to be clinically significant). Although direct statistical comparison with published data on kidney lengths in 203 U.S. children was not possible, plots of the three sets of data were strikingly congruent.
Despite expectations that smaller body size in Hong Kong children might equate to smaller kidneys, comparison with 2 sets of Western data showed no clinically significant difference in renal length between the 3 groups.
本研究旨在确定香港华裔儿童肾脏长度的正常范围，并与西方数据进行比较。
前瞻性地检查了250名接受常规腹部超声检查的儿童，记录每个儿童一侧肾脏的最大长度。年龄范围从新生儿到19岁，其中女孩109名，男孩141名。来自澳大利亚儿童的类似数据涉及554名年龄从新生儿到14岁儿童的双侧肾脏最大长度。其中女孩361名，男孩193名。所有儿童均无已知肾脏疾病。
女孩和男孩的平均肾脏长度之间无统计学显著差异。对香港和澳大利亚的数据进行统计学比较显示，除8至12个月龄组外无显著差异（该差异不太可能具有临床意义）。虽然无法与203名美国儿童已发表肾脏长度数据进行直接统计学比较，但三组数据的图表极为相似。
尽管预计香港儿童体型较小可能与较小的肾脏等同，但与两组西方数据比较显示，三组之间肾脏长度无临床显著差异。
