The kidney volume is an indicator of its size, which depends on the length, breadth and thickness. It can therefore be useful as a quantitative index of value in taking decision during urological management. This study evaluated the kidney volume, length, breadth and thickness among adult Nigerians using MDCT. This research involved retrospective review of abdominal MDCT scan images of 301 patients (male 181, female 120) age (20-65yrs). The data processing includes extra-polating 3D dimension from computer tomography and measuring the maximum length, breadth and thickness of each kidney image. Using clinical prolate ellipsoid formula ( (kidney index) as kidney volume. Statistical analysis used includes mean, mode, median correlation coefficient and t-test. The kidney volume for male (157.90 cm3) is larger than female kidney volume (156.60 cm3). The volume of left kidney (165.70cm3) is larger than right kidney volume (149.40 cm3). The left kidney (9.96 cm) is longer than the right kidney (9.86 cm). Correlation coefficient between, the left kidney volume and left kidney length (r = 0.288); breadth (r = 0.565); thickness (r =0.719) while Correlation coefficient between the right kidney volume and right kidney length (r =0.286); breath (r =0.554) and thickness (r = 0.770). Kidney volume, length, breadth and thickness for adult Nigerians were established in this study using MDCT as against previous study estimating volume of kidney using its length only as is in ultrasound, carried out in Eastern Nigeria. These baseline values obtained in this investigation can be used as standard to select appropriate kidney donor and appropriate recipient kidney. The values will also be useful to monitor transplanted kidney in routine follow up, in recipient patient, whenever the need arises for Nigerians.
