In the modern days there is a high prevalence of Hypertension, Non-Insulin dependent Diabetes Mellitus, cardiovascular disorders and soon. Barkers Hypothesis stated that low birth weight of fetus leads to Low nephron number is a factor that is responsible for these clinical conditions. In the work towards this I have studied the fetuses of various gestations, I have studied 50 fetuses of which 30 males and 20 females were observed various renal parameters like Length, width, thickness, number of lobulations and weight of the kidney. Morphometric parameters of kidney play a vital role in estimating the gestational age. The major problem in deciding gestational age of the fetus is bleeding during implantation is wrongly interpreted as last normal menstrual period by women results in abnormal gestational age. This problem can be solved by the ultra sound measurement of renal Parameters in addition to various regular parameters like crown rump length and crown heel length and so on. In the current study there are details obtained of various morphology and morphometric analysis of fetal kidneys of different age groups which are tabulated, described and discussed with various studies conducted at different time spans. The following research contributes in solving the problem with regarding gestational age finding.
