“…This may suggest a relationship between body height and renal length, especially with the left kidney which agrees with Rafat Saeed et al [9]. Our sonographic measurements of the kidney and spleen are correlated with previous studies [10][11][12][13][14][15][16][17][18][19][20].…”

A person's body weight, height, and age influence the size of their abdominal organs. Ultrasound imaging is a noninvasive, radiation-free, fast, low-cost method of evaluating the urinary system and measuring different abdominal organs. The purpose of this study was to correlate body measurements with renal and splenic measurements. A total of 94 university students from both genders were studied by the radiology department at the University of Hail between September 2017 and December 2019. An ultrasonographic scan was performed on all subjects to measure the kidney and spleen length. The respondents were recorded by age, sex, weight, and height. The left kidney is particularly affected by body height and renal length. It was not found that gender and renal length are significantly correlated. Our study revealed no significant relationship between BMI and renal length. A correlation exists between splenomegaly and renal length. Several previous studies have found a strong correlation between body height and renal length. In addition, there was a positive correlation between splenic size and height, as well as between mildly enlarged spleens and top normal left kidney sizes. Neither gender nor BMI had a remarkable correlation with renal length in our study. More studies regarding this area are recommended and will be valuable.

“…It is well known that kidney size (RL, RW, RT and RV) is related to age, height and weight. Almost all studies have shown that height correlates best with kidney length ( 10 , 13 , 15 , 16 ), and our findings support this conclusion, with height being the most relevant factor, followed by age and weight. Our results also showed that height correlated best with kidney width, thickness and cortical thickness, followed by age and weight.…”

“…Third, the use of RV to assess kidney size has a higher sensitivity and accuracy than the use of two-dimensional parameters (length, width and thickness). This is mainly due to the individual variability of kidney morphology and the fact that changes in twodimensional RSP caused by kidney disease are not as sensitive as changes in RV (13,14). However, RV measurement is not always available in some hospitals.…”

“…By using these imaging methods, some researchers have measured the morphology of kidneys in children and established the criteria for normal kidney morphology, especially concerning normal size range. However, the criteria in these reports are not necessarily universal because of the influence of ethnic factors on the morphological characteristics of the kidney (13)(14)(15)(16)(17).…”

PurposeOur aim was to investigate the normal reference value and to establish an estimation formulae for renal structural parameters (RSPs) based on large-sample CT data of Chinese children, which can provide a data reference for the clinical assessment of kidney development and diseases in Chinese children.Materials and MethodsA total of 438 children aged 0–17 years with normal renal CT images and basic indices were continuously collected. The bilateral RSP, including renal length (RL), renal width (RW), renal thickness (RT), renal volume (RV), renal cortical thickness (RCT), renal artery diameter (RAD) and renal CT value, were measured. Kendall's rank correlation was used to analyze the correlation between RSP and sex. Pearson's correlation was used to analyze the correlation between RSP and age, height and weight. Differences in the RSP of bilateral kidneys were analyzed via a paired samples t-test. Multiple linear regression was used to analyze the multivariate relationships between RSP and basic indices and establish the estimation formula of RSP.ResultsThe RSP of normal kidneys showed a dynamic increasing trend with age, except for the CT values. The reference value ranges (95% confidence interval) of normal RSP for each age group were determined. Pearson correlation analysis demonstrated strong correlations between RSP (RL, RW, RT, RV, RCT and, RAD) and basic indices (age, height and, weight), with height exhibiting the greatest correlation coefficient, followed by age or weight. Kendall's analysis showed that none of the RSPs were correlated with sex. The RL, RW, RV and RAD of the left kidney were larger than those of the right kidney, and the RT and RCT of the right kidney exhibited opposite results. Multiple linear regression analysis demonstrated a significant linear relationship between the RSP (RL, RW, RT, RV and, RCT) and the variables of the basic indices. The estimation formulae for calculating the RSP were established.ConclusionThis is the first Chinese study to report of the trends, normal reference values and estimation formulae of normal RSP based on large-sample CT data. These results can provide data references for assessing adequate kidney growth or disease damage in Chinese children.

“…In a study of normal kidney volume changes in growth and development of 321 Asian children, Rongviriyapanich et al found mean growth rates for the left and right kidneys of 11.48% and 7.66% per year, respectively, and mean increases in kidney volume of 8.60% per year for males and 11.45% per year for females [41]. In the control kidneys in the current study, the mean volume increases per year were 10.42% on the left side (n = 8) and 12.65% on the right side (n = 3), and males and females had mean increases of 9.91% and 11.96% per year, respectively.…”

The purpose of this study was to analyze renal late effects after proton beam therapy (PBT) for pediatric malignant tumors. A retrospective study was performed in 11 patients under 8 years of age who received PBT between 2013 and 2018. The kidney was exposed in irradiation of the primary lesion in all cases. Kidney volume and contour were measured on CT or MRI. Dose volume was calculated with a treatment-planning system. The median follow-up was 24 months (range, 11–57 months). In irradiated kidneys and control contralateral kidneys, the median volume changes were −5.63 (−20.54 to 7.20) and 5.23 (−2.01 to 16.73) mL/year; and the median % volume changes at 1 year were −8.55% (−47.52 to 15.51%) and 9.53% (−2.13 to 38.78%), respectively. The median relative volume change for irradiated kidneys at 1 year was −16.42% (−52.21 to −4.53%) relative to control kidneys. Kidneys irradiated with doses of 10, 20, 30, 40, and 50 GyE had volume reductions of 0.16%, 0.90%, 1.24%, 2.34%, and 8.2% per irradiated volume, respectively. The larger the irradiated volume, the greater the kidney volume was lost. Volume reduction was much greater in patients aged 4–7 years than in those aged 2–3 years. The results suggest that kidneys exposed to PBT in treatment of pediatric malignant tumor show continuous atrophy in follow-up. The degree of atrophy is increased with a higher radiation dose, greater irradiated volume, and older age. However, with growth and maturation, the contralateral kidney becomes progressively larger and is less affected by radiation.
