9-13 cm: With an ultrasound evaluation, the normal kidney size is 9-13 cm. One kidney may be up to 1.5 CM difference in size from the other and still be in acceptable range. Kidney sizes in females may be some smaller than in males but evenso a kidney smaller than 9 CM is abnormally small.
The kidneys are essential organs in the body which function to remove water and waste products. They also produce important hormones such as erythropoietin, Vitamin D, and renin.The kidneys are located in the back of the abdomen, one on each side of the spinal column, at about the level of the lower ribs.The average weight of an adult human kidney is approximately one-quarter pound. Each kidney is approximately 4 inches long, 2.5 inches wide, and 1.5 inches thick.he kidneys also have a hormonal role. They are in part responsible for the conversion of Vitamin D to its active metabolite, which is important in the absorption of calcium from the intestine. Erythropoietin is manufactured by the kidney and stimulates the bone marrow to produce red blood cells.
