Measurement of Normal Adult's Kidney Volume Using Ultrasonography

Abstract

The renal size is a very useful diagnostic parameter in the practice of medicine, since is affected by various factors, it is necessary first to determine the normal value. This study was carried out on 50 adult patients (25 females, 25 males) who are found to be of unknown renal diseases were examined according to the age, sex & BMI, aging between 16 - 65 years, during the period from July to October, 2016 in Elehtiati Elmarkazi Hospital. Measurement includes length, width and thickness estimation of the renal volume which is obtained by multiplying the three variables by 0.523, the factor age, sex, body mass index and right and left kidney side are statically analyzed. The mean right kidney length is (10.16 ± 0.61cm) …. The mean right kidney width is (4.61 ± 0.30cm) …. The mean right kidney depth is (4.10 ± 0.25cm). The mean left kidney length is (10.56 ± 0.53cm) …. The mean left kidney width is (4.83 ± 0.29cm) …. The mean left kidney depth is (4.41 ± 0.24cm). The mean right kidney volume is (100.55 ± 12.29cm3) and the mean left kidney volume is (116.95 ± 11.58cm3), Length did not significantly differ between right and left. However, the kidney width in the right is smaller than the left one. The only significant factors affecting the renal volume is the sex, age, BMI and right or left side. The study concludes that there was no relation between renal volume and BMI, also there was no relation between renal volume and age. The volume in male (106.06, 122.39) is slightly more than in females (95.03, 111.50)… (RKV, LKV), with the left kidney volume lager than the right. The mean volume of kidney in the left side (116.95) is larger than the right one (100.55).
