In this research, foetal kidney length was compared with other biometric parameters, such as “biparietal diameter (BPD), abdominal circumference (AC), head circumference (HC), and femur length (FL)”, in order to examine the relationship between foetal kidney length and gestational age during the third trimester of pregnancy. A tertiary care centre hosted prospective cross-sectional research including 150 third-trimester pregnant women. The ultrasound and the date of the last menstrual cycle were used to calculate gestational age. Foetal kidney length, BPD, AC, HC, and FL were determined using established methods. Correlation coefficients, comparison analyses, and subgroup analyses based on gestational age were all included in the statistical research. There was a significant positive connection (r=0.85, p<0.001) between gestational age and the length of the foetal kidney. Foetal kidney length was shown to be comparable to other biometric characteristics by comparative research. The subgroup analysis showed that as gestational age increased, the length of the foetal kidney increased. The results indicate that foetal kidney length shows growth patterns similar to other biometric parameters and has a substantial correlation with gestational age. The significance of a comprehensive strategy for foetal assessment in the third trimester is reinforced by these findings. The research's conclusions have clinical ramifications for tracking foetal health and development, but more investigation is required to confirm these conclusions and consider how they might be used in standard prenatal care.
TopIntroduction
A series of minute changes in both the mother's and the fetus's physiology are part of the amazing and sophisticated physiological process that is pregnancy. Joy is derived from the expectation of new life and the wonders of gestation, but they also highlight the necessity of keeping an eye on the health and development of both the mother and the foetus (Edevbie & Akhigbe, 2018). The evaluation of numerous biometric indicators, which help in tracking foetal growth and determining foetal health, is essential to this monitoring procedure (Seilanian & Rezaie-Delui, 2013). These factors are crucial in guaranteeing a safe pregnancy and a good outcome for the mother and the unborn child (Ahmadi et al., 2015). In this regard, the measurement of the foetal kidney and its relationship to gestational age during the third trimester has become increasingly relevant and of interest in foetal medicine and prenatal care (Peixoto et al., 2017).
The third trimester of pregnancy is a crucial time during which the foetus grows and develops quickly (Schlesinger et al., 1987). Numerous complex changes take place as the foetus progresses through this stage, preparing it for independent existence outside the womb. During this time, accurate gestational age determination is essential because it enables medical professionals to keep an eye on the growth and health of the foetus (Kumar et al., 2013). Traditional methods for determining gestational age include using ultrasonography and the date of the last menstrual cycle (Drumm, 1977). Because of its accuracy and non-invasiveness, ultrasonography is considered the gold standard for determining foetal biometric characteristics and estimating gestational age (Hodlock & Horrist, 1987).
The foundation of prenatal care and foetal assessment is biometric measurement. These measurements include femur length (FL), head circumference (HC), abdominal circumference (AC), and biparietal diameter (BPD), all of which offer important insights into the developing foetus. Monitoring these biometric variables aids in the identification of any potential developmental problems or anomalies in growth that may occur during pregnancy. When it comes to clinical obstetrics and prenatal care, these metrics are essential instruments.
Despite being frequently disregarded when discussing foetal development, the foetal kidney is an organ that is extremely important to the developing foetus. Its growth is entwined with the wider foetal developmental process, and it plays crucial roles in fluid and waste disposal. Ultrasound-measured foetal kidney length provides a unique window into the foetal urinary system's development and may reveal information about the general growth and health of the foetus. Given the vital role that the foetal kidney plays in maintaining fluid balance and excreting waste, it is conceivable that the foetal kidney's growth is related to gestational age (Goldstein et al., 1987).
The purpose of this research is to investigate the relationship between the length of the foetal kidney in millimetres (mm) and the gestational age in weeks during the third trimester of pregnancy. This research also wants to compare BPD, AC, HC, and FL, as well as other biometric data, with the mean foetal kidney length. The desire to expand on current knowledge of foetal development and maybe improve clinical evaluation instruments for tracking foetal health is what drives these goals.
Numerous research conducted in the last several years has improved current knowledge of foetal development and the significance of evaluating different biometric indicators. Studies have indicated that there is a notable rise in foetal weight and length during the third trimester, which is accompanied by modifications in other biometric parameters (Tobsh, 1984). These modifications are a reflection of how dynamic the foetal environment is at this time. To fully evaluate foetal development, it is still necessary to look at any possible relationships between gestational age and less well-researched biometric measures, like foetal kidney length.
