summary

When we are pregnant, we need to pay attention to the health of the fetus. When my friend is pregnant, there is fetal hydronephrosis. Now let's introduce how to do with fetal hydronephrosis?

How does fetal hydronephrosis do

First of all, the collecting system of the normal fetal kidney may be slightly separated, and the separation diameter can reach 6 mm. When the gestational age is more than 30 weeks, the renal pelvis dilation ≥ 10 mm or the presence of calyceal dilation is hydronephrosis.

Secondly, if the fetal hydronephrosis is reversible, this situation is mainly in the process of fetal development, there will be temporary abnormal renal function or structure, but it will be accompanied by the child's growth and development, slowly grow better, especially after birth, due to changes in the environment, renal function returns to normal, hydronephrosis will disappear. This kind of situation is common in the fetal ureter contraction rhythm disorder caused by some reason, or the temporary anatomical structure abnormality in the process of ureter development. This kind of reducible hydronephrosis will disappear gradually with fetal development, so it is not necessary to terminate pregnancy.

Finally, the other is irreducible, which is common in congenital ureteral stricture and urinary insufficiency. If this kind of hydronephrosis fetus is born, it should be treated in time to improve its urinary system function. Although color Doppler ultrasound diagnosis can find fetal hydronephrosis, it also has certain limitations, and can not determine the real cause of hydronephrosis, let alone predict the development direction of hydronephrosis. Therefore, we should not rush to terminate the pregnancy if we find fetal hydronephrosis. We should fully solicit the clinician's diagnosis opinions, and closely observe the development of fetal hydronephrosis. After a period of time, we should do a color B ultrasound again to understand the development trend of fetal hydronephrosis.

matters needing attention

In the case of fetal hydronephrosis, we should pay close attention to the development of the situation, but also under the guidance of the doctor for reasonable conditioning, do not rush to do artificial termination of pregnancy.
