Sonographic Measurement of Normal Kidney Volume in Adults

Abstract

This is cross sectional study was performed at Bahri teaching hospital in Al Khartoum state from (December 2018– April 2019). The aim of the study was to measure the adults normal kidney volume and find the correlation between the volume and the age , sex and the body mass index The study include 50 adult pts with normal renal status (25 of them males and 25 females) were evaluated by ultrasound. The study exclude patients less than 18 years, pregnant woman, pts with chronic rend disease , congenital anomalies and patients with history of hypertension or diabetes mellitus used real time machine 3.5 Mhz to do longitudinal and transverse scanning to find the length-width and depth of the kidneys (kidneys measurements) then the volume. The data collected by data sheet showed the variables of the study sex, age and body mass index and the kidneys volume. Study found that kidneys volume is larger in males than females. With no significant difference. The mean volume of the right kidney is (105.87 ± 10.52 cm3 ) and the mean of the left kidney volume 117.5 ± 11.64 cm3. also there was a significant difference in both kidney volume in different age group and negative learner correlation between age and kidneys volume according to the formula y = -0.451x+122.8 for the right kidney and y =-0.482x + 135.7 for the left kidney . y: the kidney volume, x: the patient age. The study found there are positive relation between the kidney volume and the body mass index with linear relationship between them according to the formula y =1.927x + 55.95 for right kidney and y = 1.88x + 68.61 for the left kidney y: the kidney volume, x: the body mass index. The study recommended further study with increase number of data for more accurate results. And further study measure the normal volume of other organ’s and correlate them with this study variables Assessment of the kidneys volumes should be a routine evaluation of Abdominal ultrasound investigation
