Correlation of Renal Dimensions and Glomerular Filtration Rate With Height, Weight, Body Mass Index, and Body Surface Area in Children

Abstract

Objective: The objective of the study was to estimate glomerular filtration rate (eGFR) and renal dimension and establish a correlation with age, weight, height, body mass index (BMI), and body surface area (BSA) of children and to measure renal dimensions (craniocaudal length, anteroposterior length, and transverse length) of both kidneys of 1–10 years children.
 Methods: A total of 500 children from 1 to 10 years old were screened by ultrasonography to measure renal craniocaudal length, anteroposterior length, and transverse width of the kidney. Length, width, thickness, and cortical size of the kidneys were also measured.
 Results: There was a positive correlation of renal dimension with age, weight, height, BMI, and BSA. There also was a positive correlation of eGFR with other renal parameters.
 Conclusion: Renal dimension and eGFR were correlate with age, weight, height, BMI, and BSA in children.

Pediatric renal transplantation—A UNOS database analysis of donor–recipient size mismatch

“…BSA, which is calculated based on weight and height, has been proven to correlate well with kidney volume. [11][12][13][14] Thus, a small number of large studies have investigated whether the relation between donor and recipient size, expressed using BSA, has an impact on renal transplant outcomes. All these included adult recipients [15][16][17][18] but two, one that included adolescent recipients 24 and one that included both adult and pediatric recipients.…”

“…Many studies have shown an association between kidney size and various anthropometric parameters, such as weight, height, body mass index (BMI) and BSA. BSA, which is calculated based on weight and height, has been proven to correlate well with kidney volume 11–14 …”

“…There is strong evidence in the literature that kidney size correlates well with body size as it is estimated by body surface area (BSA) 11–14 . Thus, a few studies have tried to use the donor's size as an indirect way to evaluate renal graft size and assess the role of size mismatch between donor and recipient in renal transplantation, mainly focusing on adult population 15–18 .…”

[15][16][17][18] However, the role of renal graft size, and size mismatch between donor and recipient has not been adequately investigated in the pediatric population, with only a small number of studies looking into this.…”
