Bilateral enlargement of fetal kidneys with Pregnancy of about 35 weeks.

This video shows Bilateral enlargement of fetal kidneys with Pregnancy of about 35 weeks.
The average fetus at 35 weeks is around 46.2cm long from head to heel and weighs about 2.4kg. That's approximately the height of 2 bananas and the weight of a honeydew melon. Your baby is getting chubbier, which will help them to stay at the right temperature when they're born.
The mean renal width of fetal kidneys in the third trimester was 18 mm,23 mm, and 25.5 mm in premature, mature, and full-term fetuses respectively. The mean renal thickness of fetal kidneys in the third trimester in was 17.6 mm, 22.2 mm, and 24.5 mm in premature, mature, and full-term fetuses respectively.
Fetal Hydronephrosis is one of the most commonly diagnosed fetal anomalies and occurs when one or both of a baby's kidneys enlarge due to urine blockage. Normally, urine flows from the kidneys to the bladder through thin tubes called ureters.
Fetal hydronephrosis is caused by an obstruction to what should be a free flow of urine out of the kidney. An example of this is kinking of the ureter. It may also be caused by an abnormal backwashing of urine from the bladder back into the kidney. An example of this is vesicoureteral reflux or "reflux."
Hydronephrosis is a condition where one or both kidneys become stretched and swollen as the result of a build-up of urine inside them. It can affect people of any age and is sometimes spotted in unborn babies during routine pregnancy ultrasound scans. This is known as antenatal hydronephrosis.
Birth defects in the urinary tract may cause hydronephrosis. Even when birth defects are the cause, hydronephrosis may be mild and may improve as the child gets older. However, birth defects may also cause hydronephrosis that is severe or gets worse over time.

Disorders of fetal growth, such as intrauterine growth restriction (IUGR) and Fetus large for gestational age (LGA), have been found to have a profound effect on the development of the fetal kidney. Abnormal kidney development is associated with hypertension and chronic kidney disease later in life.
