Kidney dimensions in ultrasound compared to somatometric parameters in normal children

Abstract

In 196 children aged between 4 weeks and 16 2/12 years a sonographic investigation of kidneys was performed and put into relation to somatometric data including bodyweight (BW) bodylength (BL), length of the trunk and the upper and the lower limb, breadth of thorax and pelvic, head circumference, maximum cranial length and maximum cranial breadth. None of the children had signs of renal disorder. Morphometric data, as kidney length, width, depth, parenchymal areas in longitudinal and transverse sections and the prolate ellipsoid volume (PEV) were documented. The children were divided into five groups (group 1: 2-6 months, group 2: 6-31 months, group 3: 31-99 months, group 4: 99-131 months, group 5: 131-194 months). Mean values of all parameters were calculated. For each group a multiple regression analysis was performed and a regression equation of kidney length, parenchymal areas and volume was established. This method allows an individual determination of renal size and parenchymal mass.

Normal liver, spleen, and kidney dimensions in neonates, infants, and children: evaluation with sonography.

“…The reason is that the intraabdom inal visceral organs are larger in children than in adults when compared with total body volume. This finding leads to the con several previous studies [1,7]. However, the selected age groups in those studies present a wide range like 5 years, as in the studies of Rosenberg et al [1] and Dremsek et al [7] (whereas our selected age groups had an age range of 3 months or 2 years).…”

Sonographic Assessment of the Normal Dimensions of Liver, Spleen, and Kidney in Healthy Children at Tertiary Care Hospital

“…Previous studies done by Christophe, Han, Dremshek also did not find any significant difference in organ sizes between two sexes. [7][8][9] This indicates that sex does not influence on the size of the organ. However, the difference in size of organs between the two sexes needs to be confirmed in larger pediatrics population.…”

To the best of our knowledge, our study, which aimed to investigate the normal limits of the liver, spleen, and kidneys, is the first series in the literature to determine the normal limits of organ dimensions among Nepalese children.…”
