Measurement of Kidney Volume with Multi-Detector Computed Tomography Scanning in Young Korean

Abstract

PurposeKidney volume is regarded as the most precise indicator of kidney size. However, it is not widely used clinically, because its measurement is difficult due to the complex kidney shape. We attempted to evaluate the normal kidney volume in young Korean men by using multi-detector computed tomography (MDCT).Materials and MethodsWe retrospectively reviewed MDCT data of young Korean men (113 patients). After data processing, we measured the volume and length of the kidneys. Body parameters (height, body weight, body-surface area, and total body water) and laboratory data were collected. Glomerular filtration rate (GFR) was calculated using Cockcroft-Gault (CG) equation.ResultsThe mean kidney volume was 205.29 ± 36.81 cm3; and mean kidney length was 10.80 ± 0.69 cm. The former correlated significantly with height, body weight, body-surface area, and total body water (p < 0.05, correlation coefficient : γ = 0.328, 0.649, 0.640, and 0.638, respectively). The latter also correlated significantly with all body indexes, however the correlation was weaker, except with height (p < 0.05, correlation coefficient : γ = 0.457, 0.473, 0.505, and 0.503, respectively). Only kidney volume significantly predicted estimated GFR (adjusted R2 = 0.431, F = 85.90 and p < 0.05).ConclusionThe kidney volume measured with MDCT is correlated well with body parameters, and is useful to predict renal function.

Morphometric Parameters of the Human Adult Kidney: An Anatomical Study

“…Emamian et al reported that the median renal lengths were 11.2 cm on left side and 10.9 cm on the right side. According to a study by Shin et al (2009), the mean right and left kidney lengths were 10.7 ± 0.76 and 10.9 ± 0.72 cm respectively. The left kidney was significantly (p<0.05) longer than right kidney.…”

Relationship of renal morphology on 3-dimensional ultrasonography with renal pathologic findings and outcome in biopsy-proven nephropathy

“…However, kidney volume estimated by using computed tomography (CT) predicted eGFR in healthy young adults, whereas kidney length was reported to be not related to eGFR (1). In patients with CKD, kidney volume is a more sensitive indicator of eGFR than kidney length (2).…”

“…Kidney morphology has been used to predict renal functions in healthy young adults (1). Several studies have also demonstrated the clinical implications of kidney morphology in pathological status.…”

A study concerning morphometry of abdominal aorta branches and abdominal viscera: relations and correlation

“…Spleen length is known to increase with male sex, height and weight and decrease with age although level of correlation varies across various studies [21,41]. Kidney length is also known to increase with male sex, height and weight and decrease with age after the age of 50 [31,32,42,89,97]. Kasiske and Umen [43] support that, for kidney, correlation exists only between organ weight and body surface area.…”
