Evaluating the Relationship Between Fetal Kidney Length and Gender in Late Pregnancy: A Sonographic Approach

Background: Ultrasound monitoring of fetal kidney length is of central importance to our assessment of intrauterine growth. It correlates strongly with gestational age and also with weight and gender. Measurement according to gender is more accurate and aids early diagnosis of anomalies. The aims to determine the relationship between fetal kidney length and gender during the second and third trimesters using ultrasonography. Method: Kidney length measurements were obtained by ultrasound of ۲۷۹ pregnant women in Baghdad in a cross-sectional study, associating kidney length with demographic and fetal growth parameters. The Amniotic Fluid Index (AFI) was also checked. Too low or too high levels (<۵ cm or >۲۴ cm) indicate possible problems that further testing is needed. Results: A study of ۲۷۹ pregnant women established highly positive relationships between foetal kidney length and BPD, FL, AC, and foetal weight, which means that kidney growth is proportionate to the foetus. Female kidneys were relatively longer than male kidneys, although the difference was not statistically significant. The upper-normal AFI added to the length of the kidneys, which were the longest. This proves the fact that amniotic fluid is important to the development of the foetus. Conclusion: In the study, gender-based differences in fetal kidney lengths were not statistically significant. However, significant differences were seen across the AFI groups, with the larges t kidney lengths belonging to the upper normal AFI category. Kidney length also increased significantly with gestation age, being strongly correlated with BPD, FL, and AC.
