“…1,3 In spite of the fact that some authors found larger kidney volume in men than in women 3 , some other authors could not find any influence of sex on the kidney volume. 8,18 No significant difference was established between kidney dimensions in males and females of two studied groups. Only the width of the kidneys was significantly bigger in healthy men than in women.…”

“…Burkhardt et al found significant correlation between body height and kidney parenchyma volume in elderly 8 . In healthy controls in our study, there was a significant correlation between the kidney width, depth, volume and age, body weight, body surface and BMI (Table 5).…”

“…9,20 Burkhardt et al studied correlation between kidney dimensions and function in elderly and found the best correlation between the kidney parenchyma volume and creatinine clearance. 8 They even stated that the deficit of parenchymal volume could be verified sonographically before the loss of renal function. Since the most of kidney volume is not made up of the parenchyma, it turns out that the parenchymal volume may correlate better with renal function, 23 what was also found in our study both in whole group of patients and patients divided to subgroups by sex ( Table 3).…”

“…Decline of different parameters of kidney size was described in parallel to diminishing of kidney function in chronic renal failure. 1,[6][7][8][9] Reduced parenchymal thickness is also well known in patients with chronic kidney diseases (CKDs) as well as in elderly people. 3,8,10 The objective of this study was to compare the kidney echosonography characteristics with the kidney function and anthropometric characteristics in healthy subjects and patients with the CKD.…”

“…On the other hand, even in the absence of kidney disease, renal size also diminishes with increasing age. 1 It is controversial whether decrease in renal function is secondary to reduced nephron number (reduced renal length) or vice versa. Currently, there is no normogram defining kidney dimensions in middle-aged and elderly patients.…”

Purpose: A few studies investigated renal size using computed tomography (CT) in middle-aged and elderly patients while taking renal function into account. Thus, we aimed to assess kidney dimensions and their predictors in patients without known renal disease by multi-detector computed tomography (MDCT). Methods: This is a 6-month-long prospective observational study. Estimated glomerular filtration rate (eGFR) was calculated with Cockcroft-Gault (CG) and modification of diet in renal disease (MDRD) formulas. Pole-to-pole kidney length (R1) was determined from coronal and sagittal oblique images. Kidney length (R2), width (R3), and parenchymal thickness were measured in axial slices. Results: The data of the 930 patients were included in this study. CG-eGFR was more closely correlated with R1, R2, and R3 than MDRD-eGFR. CG-eGFR, female gender, and presence of diabetes mellitus were independent predictors of R1 size in logistic regression analyses. Conclusion: Kidney sizes diminish with advancing age. CG-eGFR shows a better correlation with kidney dimensions compared with MDRD. Overall, age was a stronger determinant of eGFR than renal dimensions.

AimsHeart failure (HF) is usually associated with complications of other organs. Renal impairment is seen in a significant proportion of HF patients and is characterized by worsening renal function (WRF). WRF can be used for predicting symptom exacerbation in systolic HF. This study aimed to determine the prevalence and risk factors of WRF among hospitalized patients with systolic HF.Methods and resultsIn this cross‐sectional study, data from medical records of 347 hospitalized patients diagnosed with HFrEF from 2019 to 2020, admitted to Tabriz Shahid Madani Heart Hospital, who met the predefined inclusion criteria, were retrieved. Patients were divided into two groups based on the in‐hospital occurrence of WRF. Laboratory tests and para‐clinical findings were collected and analysed using SPSS Version 20.0. Statistical significance was accepted at a P value of <0.05. In this study, 347 hospitalized patients with HFrEF were included. The mean (standard deviation) age was 62.34 (±18.87) years. The mean (SD) length of stay was 6.34 (±4) days. According to our findings, 117 patients (33.71%) had WRF. Following multivariate analysis of potential predictors of WRF occurrence, hyponatremia, haemoglobin concentration, white blood cell count and prior diuretic use were found to be independent predictors for WRF occurrence in patients with systolic heart failure.ConclusionsThis study revealed that in patients with WRF, mortality rate and length of stay were significantly greater than those of patients without WRF. Initial clinical characteristics of HF patients who developed WRF can help physicians identify patients with a higher risk of WRF.
