“…The equation from that study, 4.98 + 0.1 55 x age (month), generally overestimates the renal length in our sample [2]. Two of the previous studies predicted renal volume, a more complicated measurement of kidney size than length [3,5]. This measurement is more cumbersome for the clinician and radiologist, and rather than deal with this cumbersome measurement, most sonographers ignore the standards.…”

“…In normal kidneys no alteration of the calculated parenchymal volume is expected using a PEV, but the result is falsified when morphological abnormalities (hydronephrosis, sinus lipomatosis, cysts, tumors, abscesses, hemorrhages) are present. The method of stepped sections [12,21,22] subtracting non-parenchymal structures is the most precise method for measuring the renal parenchyma. We investigated 65 patients older than 8 years by applying this method.…”

Kidney dimensions in ultrasound compared to somatometric parameters in normal children

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.

“…This would be appropriate for internal comparisons which are mainly focused on ranking in terms of renal growth characteristics. However, the results of published studies indicate that renal volume is a better representation of renal weight and growth than renal length [13,14]. Therefore, we believe that is it still relevant to measure renal thickness, even if the variation of the measurement is quite large.…”

The aim of the investigation reported here was to assess the intraobserver and interobserver variability of renal measurements in children. The study comprised 56 paired measurements in 28 children (median age 7.5 years, range 3.0-15.0 years) without renal or ureterovesical anomalies. Intraobserver and interobserver reproducibility was assessed by repeated measurements of the left and right renal length, width, and thickness. Intraclass correlation coefficients (ICCs) with the corresponding 95% confidence interval (CI) were calculated. Bland and Altman plots were computed to assess the agreement of the measurements. Limits of agreement +/- 2 standard deviations (SD) for the mean differences in renal measurements were derived. Intraobserver ICCs ranged from 0.93 (left and right renal width and right renal thickness) to 0.99 (left renal length), and interobserver ICCs ranged from 0.64 (right renal thickness) to 0.90 (right renal length). Limits of agreement in the Bland and Altman plots ranged from -8.0 to 9.2% (intraobserver left renal width) to the widest limit from -18.0 to 19.2% (interobserver left renal length). Overall, this study demonstrated the good reproducibility and agreement of most renal dimensions in children measured by ultrasound (US). Based on these results, we conclude that US is an appropriate measure to assess renal dimensions in both clinical and epidemiological studies.
