How the lack of a right kidney in the 6th month of pregnancy is caused

Missing right kidney, a congenital developmental abnormality, was found in the 6th month of pregnancy.
The absence of the right kidney is mainly due to the abnormal development of renal tissues and ureteric buds, thus affecting the normal development of one side of the kidney and causing the absence. For those with normal kidney function on the other side, there are no obvious clinical symptoms and it is often found during physical examination.
In the case of maternal individuals with right renal agenesis, regular review of renal function is required. The intake of high salt food and high protein food should also be strictly controlled to avoid aggravating the burden on the kidneys.
If it is clear that the fetus is missing the right kidney, further examination is needed to clarify whether there is a combination of other developmental malformations.
If the fetus has multiple developmental malformations, the pregnancy can be terminated under the guidance of the doctor. If the fetus has only a single missing kidney and the other kidney is functioning normally, no special treatment is needed.
