Measurement of Fetal kidney and Renal Pelvis among Sudanese using Ultrasonography

Abstract

Accurate estimation of normal antenatal fetal kidney size is very important, thus determination of normal measurements was help in early diagnose of fetal renal abnormalities. This crossectional studywas done tomeasure fetal kidnysonographically during pregnancy. The aim of this study was to establish reference charts for fetal kidney length, width and renal pelvis diameter. The study was carried out in AlshifaModern Medical Centre from November 2016 to March 2017. The study includes 50 normal pregnant womenwith singleton pregnancy between (17-39) weeks of gestation. Sonographic examination was performed, longitudinal and transverse diameter of fetal kidney and antero posterior diameter of renal pelvis were measured, with the average being used for analysis. The study demonstrated that the mean kidney length in (17-39) weeks of gestational age was ±3.61 cm;the mean width of kidney was±1.7210 cm,while the mean renal pelvis diameter was ±0.9528 cm. These measurements correlated significantly with gestational age.It was noticed that the increase in renalvolume during pregnancy is exponential until birth. In conclusion, given that renal pathology often presents late in pregnancy, our reference charts for size and volumeof the fetal kidney may be useful in cases of diagnostic problems. This finding may alsobe useful for the detection and evaluation of abnormal growth.
