What are the causes of fetal urinary system malformations?

1. Environmental factors such

as excessive exposure to pesticides, lead, gas and other harmful chemicals during pregnancy, or long-term inhalation of second-hand smoke, will affect the development of the fetus, leading to urinary system abnormalities.

2. Genetic factors

urinary system abnormalities and autosomal recessive inheritance, when there are immediate family members sick, the probability of their offspring suffering from urinary system abnormalities will increase.

3. Pregnancy infection

If infected by bacteria, viruses and other pathogens during pregnancy, inflammatory substances and toxins can be absorbed by the fetus through the placenta, which is also easy to cause urinary system abnormalities.
