“…Serial measurements also can provide information regarding disease progression or stability. A number of reports have described ultrasonography measurement of renal length and volume in the healthy Western population, (7)(8)(9)(10)(11)(12), but there are scant data regarding MR measurement of renal dimensions in adults. and neither study was designed to estimate reference values for the length and volumes of kidneys in patients without intrinsic renal disease.…”

“…First, our work demonstrates that kidney lengths and volumes by MRI disc summation (men 12.4 Ϯ 0.9 cm for length and 202 Ϯ 36 ml for volume; women 11.6 Ϯ 1.1 cm for length and 154 Ϯ 33 ml for volume) are consistently larger than reported. Specifically, the current literature reference values, principally from ultrasonography measurements, suggest that a normal adult kidney is approximately 11 Ϯ 1.0 cm long (7)(8)(9)(10)(11)(12), with a normal volume of 110 to 190 ml in men and 90 to 150 ml in women (16). An important caution is that these reference values are based on ultrasonography data where calculations are derived from the ellipsoid formula, which has the previously noted inherent geometric assumption limitations.…”

“…A number of investigators have reported reference values for renal length (7)(8)(9)(10)(11)(12) and, to a lesser extent, renal volume in healthy adults (7,8), as measured by ultrasonography. The ultrasonography method that is used to measure kidney volumes is two-dimensional in nature, is subject to operator dependence, and uses geometric assumptions about the shape of the kidney to estimate kidney volumes.…”

The objective of this magnetic resonance imaging (MRI) study was to (1) test the validity of the ellipsoid formula for estimating kidney volume using ex vivo and in vivo models and (2) establish a normal range of values for kidney length and volume in patients with no known history of renal disease. The volumes of five excised porcine kidneys were measured by (1) disc-summation method, (2) ellipsoid formula, and (3) water displacement method. In a retrospective, consecutive group of clinically referred patients (n ‫؍‬ 150; 300 kidneys), individual kidney volume and length were calculated by the disc-summation method and by multiplanar reformation of MRI data, respectively. For comparison, kidney volumes also were calculated using the ellipsoid formula in all patients. Renal volume that was obtained by MRI using the disc-summation method was within 5% of the volume that was determined by the water displacement method, independent of the spatial resolution of the MRI technique used. Data from both the in vivo and the ex vivo models revealed that the ellipsoid formula that commonly is used in ultrasonography underestimates renal volume by 17 to 29% compared with the disc-summation method (P < 0.05). As measured by MRI (mean ؎ SD), kidney lengths were 12.4 ؎ 0.9 cm for men and 11.6 ؎ 1.1 cm for women, and kidney volumes were 202 ؎ 36 ml for men and 154 ؎ 33 ml for women. The results from the ex vivo MRI study show that the kidney volume that was obtained using the disc-summation method is within 5% of the true kidney volume as measured by the water displacement method. The ellipsoid formula consistently and significantly underestimates the true kidney volume. The length and the volume of kidneys that are obtained by MRI in patients with no known history of intrinsic renal disease are greater than the commonly quoted reference values that are obtained by ultrasonography.

“…Creatinine Clearance (ml/min), which in turn estimates glomerular filtration rate (GFR) in ml/min was estimated by Cockcroft-Gault Equation {CreatClear=[(140-Age)*Weight/72*Serum Creat]*0.85 in female} [5]. According to the results, patients were distributed to the following five categories, according to the described stages of CKD: ≥90 ml/min, 60 ml/min to 89 ml/min, 30 ml/min to 59 ml/min, 15 ml/min to 29 ml/min and <15 ml/min [19].…”

“…Ageing and a number of common chronic diseases like hypertension, diabetes mellitus, cardiovascular disease and their treatments are associated with significant modifications of kidney function [1][2][3]. Especially, ageing is frequently associated with loss of muscle mass, but also determines changes in kidney structure, since it is associated with a loss of renal mass by about one fourth from 30 to 80 years of age [4], and a decrease in kidneys' length by 15% from 17 to 85 years of age [5]. In the Framingham Offspring Study, it was shown that for an increase in age of ten years, the odds ratio for developing CKD was 2.56 [6].…”
