Observer Variability in Sonographic Measurement of Kidney Sizes among Children in Benin-City, Nigeria

In this prospective cross-sectional study, ultrasonography was used to repeatedly measure kidney sizes by different observers in order to determine the level of inconsistency within and between replicate measurements of kidney size by a single and different observers. Replicate sonographic measurements by a single observer are more consistent, and therefore, more reliable than replicate measurements by different observers.
Aim: To assess the level of inconsistency in replicating sonographic kidney size measurements in a population of healthy Nigerian children.
