What to do with kidney length and volumes in large individuals?

Editorial: There Is Still a Need for Kidney Volume Reference Intervals in Large Children, Adolescents, and Young Adults

“…3 Like estimated glomerular filtration rate, kidney volumes should also be calculated using the ideal body weight, which can be quickly determined using the Traub formula. 3…”

“…We have pointed out that the trunk size remains mostly preserved while the height of a person is directly proportional to the femur length regarding the acceleration of body length. 3 In other words, the acceleration of body length occurs mostly in the femur, and the impact of this on BSA is unknown. 3 We urgently need new data on BSA to accommodate the trend toward taller children in every new generation.…”

“…Kidney measurements indexed to height and body surface area (BSA) are used for evaluation, diagnosis, and longitudinal assessment in children, 1,2 but the normative data used in kidney dimension calculators may not be accurate for children from around the globe. 3 Moreover, the 1916 formula for the calculation of the BSA by Dubois and its recalculation by Mosteller seems to also be outdated due to growth acceleration and obesity. 3 For instance, Korean men gained 20.6 cm in height over the past 100 years.…”
