Evaluation of kidney size and volume is very important in the diagnosis, treatment and follow-up of kidney diseases. Ultrasonography is the preferred imaging modality which provides a safe, reliable and affordable way of imaging the kidneys in the follow up of kidney diseases..In this study, we aimed to determine the kidney volume in normal adults and try to find out which of the physical features are more related with kidney volume.

Materials and Methods:

Between June 2005 and December 2008 177 patients referred for routine abdominopelvic ultrasonography (US) were included in the study. 16 patients who had renal masses, hydronephrosis and nephrolithiasis were excluded. Height, weight, body surface area (BSA) and body mass index (BMI) of the patients were recorded. Renal ultrasonography was performed and kidney sizes were evaluated in lateral decubitis position. Kidney sizes were measured on longitudinal and transverse scan. Ellipsoid formula was used to determine the kidney volume.


A total of 161 patients 69 (42,8%) male, 92 (57,5%) female were enrolled in the study. Mean kidney volume for right kidney was 125 mL and 134 mL for left kidney in women whereas it was 149 mL for right kidney and 155 mL for left kidney in men. There was a significant difference between right and left kidney volumes (p<0.05). Right and left kidney volume, right and left renal parenchymal thickness were ssignificantly higher in males than females (p<0.05). There was a positive correlation between kidney volume and height, weight, BMI and BSA Abstract but the strongest positive correlation was between height and kidney volume.


Although kidney length is an important diagnostic marker for evaluating renal function; measurement of kidney lengtfh alone might not be sufficient. In cases where clinical and radiological residual renal capacity cannot be finalized, it is appropriate to calculate the renal volume. When evaluating the renal volume, it should be considered that the renal volume may differ depending on the body mass index, height, weight, BMI, and age.
