Background: Kidney volume is the best precise indicator of kidney size, though it is not frequently measured clinically, due to kidney shape is variable considerably. 
Aim: to estimate the relationship between total kidney volume and renal function in group of men and women with and without history of renal disease by using CT. 
Patients and Methods: Prospective study conducted on selected patients attending radiological department of Baghdad teaching hospital within a period from November 2023 till October 2024. Using computed tomography after data processing, total kidney volume was measured. Patients were divided into two groups; those with normal renal function group A and abnormal renal function group B. 
Result: The mean ± SD of total kidney volume was 303.25±80.35 cm3 for overall patients. No statistical significant correlations between the volume and gender, while only in group a show significant correlation with height, weight, or body mass index. Significant negative correlation with age in all groups and high positive correlation (r = 0.680) between volume and kidney function for overall patients while weak non-significant correlation among group A. 
Conclusion: total renal volume correlated well with renal function positively and with age inversely.
