ABSTRACT
Introduction: Ultrasound is the first imaging modality used to assess the kidneys and renal tract due to its easyaccessibility, lack of radiation and low cost. The size of kidney is considered an important indicator for variousclinical signs. Ultra-sonographic measurement of renal dimensions such as length, breadth and thickness areimportant parameters in diagnosis and management of kidney diseases as there is a close proximity betweenrenal size and its function.Aim: The aim of the present study was to ascertain the renal dimensions in adult by ultrasonography and tocorrelate with somatic parameters like age, sex, height and body surface area.Methods: This study was carried out on 118 patients (51 male & 67 female) taking measurements of 236 kidneyshaving no radiologic evidence of renal diseases. Renal dimensions of right were compared with the left. Thevolume of the kidney was correlated with age, sex, height and body surface area.Results: The present study revealed that the volume of left kidney was more than the right in both male andfemale. The size of kidney in male was larger than female. The volume of kidney showed linear relationship withthe body surface area both in male and female. However, volume of kidneys decreased from sixty years of age.Conclusion: Measurements of renal dimensions can be obtained quickly and easily with ultrasonography havingadvantage of not exposing the patients to ionizing radiation. This allowed us to find differences in relation toage, sex, weight and height. There is a gender difference in adult kidney sizes. The renal length is correlated bestwith height and body surface area.
