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
