INTRODUCTION: The gross structure of the kidney has been known to be related to its function. Hence significance deviations would be expected to affect the Sexcretions of metabolic waste and production of erythropetin, prostaglandins, and rSenin necessary for homeostasis. The aim of this research was to determine the normal kidney size and volumeof pregnant and non- pregnant women in Delta State.
METHOD: Ultrasonographic kidney measurement were performedon 142subjects ( pregnant and non- pregnant women), without known renal lesions, with the age ranging from 18- 57 years. Measurementsincludinglength, width, thickness, and estimation of the renal size was obtained by multiplying the first three variables, and renal volume was obtained by multiplying the first three variables and by dividing by two. The effect of age, body mass index(BMI) to renal variables, size and volume was statistically analysed.
RESULTS : On the right, the mean renal(length, width, thickness, size, and volume), are 9.48 + 0.86cm, 6.42 + 0.72cm, 3.99 + 0.55cm, 245.42 + 61.55cm3 and 122.71 + 30.77cm 3 . On the left, the mean renal( length, width, thickness, size, and volume), are 9.72 + 0.87cm, 6.64 +0.97cm, 4.54 + 0.87cm, 299.26 + 90.43cm3, and 149.63 +45.21cm3, for non- pregnant women. For pregnant women , on the right mean renal(length, width, thickness, size, and renal volume) are 9.75 + 0.99cm, 6.68 +0.63cm, 4.22 + 0.50cm, 279.49 +73.95cm3 and 139.97 + 36.94cm3. On the left, The mean renal( length, width, thickness, size, volume), are9.93 + 1.76cm, 6.63 +0.82cm, 4.82 +0.62cm, 324.52+ 109. 59cm3, and162.26 +54.79cm3. Left renal length, width, thickness, size and volume) was greater than right (length, width, thickness, size and volume) for pregnant and non- pregnant women.
CONCLUSION: The mean renal size and volume for pregnant women were greater than non-pregnant women also there was a slight correlation to renal size and volume to age and body mass index (BMI)..
