What does four-dimensional color Doppler ultrasound mean for renal pelvic separation?

Fetal renal pelvis separation is a relatively common condition during pregnancy. Most expectant mothers experience fetal renal pelvis separation when doing four-dimensional color ultrasound. Many expectant mothers want to know the real cause of fetal renal pelvis separation. So, what does four-dimensional color ultrasound renal pelvis separation mean? What is the reason?

What does four-dimensional color ultrasound renal pelvis separation mean?

Four-dimensional color ultrasound renal pelvic separation refers to a condition in which the fetus cannot excrete urine normally due to kidney stones, urethral malformations, etc. There are many reasons for fetal renal pelvic separation, but there is no scientific evidence to prove whether fetal renal pelvic separation will result in a boy or a girl. Although there has always been a saying in folk customs that the probability of having a boy is high in fetal renal pelvic separation, parents do not need to believe it too blindly. In fact, it is the same to have a boy or a girl.

Causes of renal pelvic separation by four-dimensional color Doppler ultrasound

1. Physiological reasons

The first thing to consider when it comes to fetal renal pelvic separation is whether it is caused by physiological reasons. Because the fetal organs are still in the process of development, the fetal renal function joints will have a slight separation. Generally, if it does not exceed 10mm after 30 weeks of pregnancy, it is mostly a normal physiological phenomenon.

2. Hydronephrosis

If the physiological reasons for fetal renal pelvis separation have been ruled out, then we need to consider whether it is due to fetal hydronephrosis. If the fetus suffers from congenital hydronephrosis and urine cannot be discharged normally, fetal renal pelvis separation will occur. Therefore, parents of fetal renal pelvis separation should also be alert to whether it is due to hydronephrosis.

3. Baby holds urine

Parents do not need to be too worried about fetal renal pelvis separation. Fetal renal pelvis separation may be related to the baby's urine retention. As the baby grows and develops, he or she will gradually have the ability to hold urine. If the baby happens to hold urine during the examination, then fetal renal pelvis separation may also occur.

4. Congenital urethral obstruction

Congenital urethral obstruction in babies is also one of the main causes of fetal renal pelvis separation. If the baby is born with urethral problems, it is very easy to develop fetal renal pelvis separation. If the fetus is born with difficulty urinating, urethral malformation, etc., they are all congenital urethral obstruction and can cause fetal renal pelvis separation.

5. Excessive amniotic fluid

According to statistics, fetal renal pelvis separation may also have a direct connection with the physical condition of the pregnant mother. Excessive amniotic fluid during pregnancy may also cause fetal renal pelvis separation. Excessive amniotic fluid during pregnancy can easily lead to fetal kidney malformation and thus lead to fetal renal pelvis separation.

The above is a detailed explanation of "What does four-dimensional color ultrasound renal pelvis separation mean? What is the cause?" I hope it can help everyone!
