Aim:
The purpose of our study was to build a multiple renal length nomogram for Hong Kong Asian children based on normal renal ultrasonography.
Methods:
All children below the age of 13 years, who underwent ultrasonography in a local Hospital in Hong Kong from 23 September 2008 to 31 January 2009 due to melamine exposure were identified.
Results:
A total of 3031 normal children were identified. Hong Kong Asian children have smaller kidneys as compared with the Western. Age, bodyweight and body height are the significant factors in the multiple nomogram model of renal length. The interaction between body ln(weight) (ln stands for natural logarithm) and age as well as body height and age are also significant in the model.
Conclusion:
Our study provides a practical multiple nomogram of renal length for Hong Kong Asian children.
