Question
What are the possible outcomes of chromosomal abnormalities? If a newborn has concurrent urinary tract abnormalities, what might happen? I have been supplementing with folic acid since the third month of pregnancy and had a fetal screening at four months, with normal results. What should I do?
Answer
There are a total of 24 pairs of chromosomes, making 48 in total. We need to identify which pair of chromosomes is abnormal to determine the outcome. Urinary tract abnormalities do not affect the fetus, but if hydronephrosis exceeds 10 millimeters, it requires further follow-up. If it exceeds 16 millimeters, it is considered abnormal. If there is a chromosomal abnormality, it is likely to cause significant harm to the child, progressing rapidly. Therefore, parents should pay more attention and seek timely treatment.
