Normogram from fetal kidney length by ultrasonographically

Foetal age estimation is very important. Foetal age can be estimated by variety of parameters such as Femur length, Bi- Parietal diameter, Abdominal circumference, Humerus length and Foetal Kidney length. Previous studies by various authors indicate that 30% of female forget their exact Last Menstrual period (LMP) [1, 2]. If exact LMP is not known then Expected date of delivery was not found. So these types of cases pose a grave challenge for treating doctor. Frequently in the emergency, unregistered antenatal cases come with the history of accident as well as assault with bleeding per vaginum. These types of cases also need treatment or Medical termination under MTP act. So this study was aimed to produce normogram using foetal Kidney length by measuring it sonographically from known registered antenatal cases coming to Gian Sagar. The Normogram was prepared with objective to use it retrospectively when LMP is not known to get foetal age using foetal kidney length.
