Sonographic Dimensions of Normal Kidney among Children

Abstract

Background: the measurement techniques vary between operators, and there is a lack in standards for measuring either renal length or volume. Individual observation shows that optimal sonographic technique varies with sonography system and transducer combination. Objectives: the purpose of this review was to combine the sonographic measurements and morphology of normal kidney among children obtained. Materials and Methods: An electronic search was conducted in CINAHL, EMBASE, and MEDLINE databases. The search resulted in 42 relevant studies, from which 8 studies were met the inclusion criteria. The information was extracted from these studies. Results: in the included studies, the length of right kidney ranged from 4 cm to 7.9 cm. Three studies from the all eight studies of this review revealed that the mean length of the right kidney was 7.6 cm, the rest five studies was with length ranged between 4.2 cm to 6.8 cm and the length of left kidney ranged between 4 cm to 8.4 cm. There are two studies found that length was equal both in right and left kidneys. Conclusion: Assessment of kidney size using sonography can be an early screening technique for these conditions especially among children.
