Separation of left and right kidneys, causes, triggers

Although the country has always advocated that it is the same for both boys and girls, many people are still curious about whether the baby in their belly is a boy or a girl when they are pregnant. Some experienced people will estimate the gender of the child based on the physical condition of the pregnant woman, such as whether the pregnant woman's belly is round or pointed. Some pregnant women will find that the left and right kidneys are separated during the examination, so what is going on?

There are so many ways to predict the gender of a baby online that it's dizzying. They all seem to be the same.

There is no scientific basis for this, but there is only one method that has something to do with the gender of the fetus, and that is the separation of the bilateral renal pelvises of the fetus. Some mothers' B-ultrasound reports will show that the fetus has bilateral renal pelvis separation. The doctor recommends a re-examination. As long as the bilateral renal pelvis separation does not exceed 1 cm, it is generally not a problem. It is likely that the baby is holding his urine and the problem will be solved by peeing after the baby is born. Expectant mothers do not need to worry. It is said that bilateral renal pelvis separation means a boy, and many mothers have indeed given birth to boys. How did this saying come about? You will understand after reading this article!

First, let’s look at the three reasons for kidney separation.

1. Holding urine

Fetal renal pelvis separation is caused by kidney stones and ureteral malformations, which prevent urine from being discharged normally, causing the renal pelvis to become filled and enlarged. When the fetus holds urine, it may sometimes be caused by a naughty baby holding urine. Holding urine causes the bladder to fill with a large amount of urine, resulting in varying degrees of increased pressure in the renal pelvis.

2. Congenital urinary tract obstruction

If the baby has congenital urinary tract problems, it may be caused by the baby's congenital urinary tract problems, such as difficulty urinating and ureteral malformation, which causes urine to accumulate in the kidneys and cause renal pelvis separation.

3. Excessive amniotic fluid

If the pregnant mother suffers from gestational diabetes, it will cause excessive amniotic fluid, which may cause fetal kidney malformation and lead to hydronephrosis. Causes separation of the renal pelvis.

Why is it said that separated kidneys mean a boy?

Among the above three reasons for bilateral kidney separation, excluding the last two pathological reasons, let's talk about the first physiological reason: the fetus holds urine, which causes bilateral renal pelvis separation. Male babies have longer urethras and are more likely to hold urine, so 90% of renal pelvis separation occurs in male babies. For some babies, this problem is solved by peeing when they are born.
