Normal Variance in Ultrasound Measured Renal Dimensions With Age, Sex and Body Habitus in A Specific Population Without Known Renal Disease

Abstract

Introduction: Evaluation and follow-up of patients with renal diseases is commonly done by renal ultrasonography. Renal size is influenced by some factors such as age, height, weight, body mass index and ethnicity. The aim of this study was to evaluate the normal range of dimensions of kidney, like length, width, thickness & volume and its correlation with age, sex, height, weight and body mass index in population of eastern Odisha by Ultrasonography. Material & Methods: Ultrasound was performed on 223 subjects. Initially the image was taken in supine and later in both lateral decubitus position. The measurements of kidney were taken from the freezed images in longitudinal axis and the transverse section obtained at the level of the renal hilum. Results: In 63.68% cases the kidney length and in 81.17% cases, the kidney volume was larger on left side. A decline trend in all the measurements of parameters beyond 50 years was observed in the present study. However, the mean volume on both sides had a slight increasing trend in 61-70 years age group.
