Normal bladder size of fetus at 40 weeks of pregnancy

When a pregnant woman is around 40 weeks pregnant, the fetus gradually matures and the fetal bladder continues to grow. At this time, B-ultrasound can be used for detection. Generally speaking, there will be no problem with the fetal bladder. Of course, a very small number of fetuses may have giant bladder. At this time, you can check with sonograms and B-ultrasound to see if the fetal bladder is normal. At the same time, you should observe whether the child's kidneys, external genitalia and spine are normal.

Normal size of fetal bladder at forty weeks of pregnancy. First: As the fetus grows and develops, the fetal bladder also continues to grow. Even within a few days of growth, the size of the bladder will be different. Of course, if there are some problems with the fetus, it can be detected by B-ultrasound, so during the prenatal check-up, if there is no problem, there is no need to worry. Second: For a fetus at the end of forty weeks, it is full-term. At this time, the fetus weighs about three kilograms. Of course, boys are slightly heavier than girls. At this stage, the fetus's internal organs are basically fully developed, the nervous system function is relatively complete, and the child's hand and foot muscles are also very developed. Third: The fetus's sensory organs and nervous system can respond to various stimuli inside and outside the mother's body. It can keenly perceive the mother's thoughts, and perceive the mother's mood, emotions and attitude towards herself. The baby should be as active as before. If the fetal movement decreases, you should go to a specialist hospital immediately.

The sonogram of fetal megacystis is mainly an abnormally enlarged anechoic area visible in the fetal lower abdomen. Doctors can use repeated B-ultrasound detection to determine whether the fetus has megacystis.

The normal fetal bladder urinates once every 1 to 1.5 hours. Therefore, if an abnormally enlarged bladder is found during an ultrasound examination in the second trimester of pregnancy, the patient should wait until the fetus urinates. If the bladder does not shrink after urination, it can be diagnosed as fetal megacystis.

The ureters, kidneys, genitalia, and spine should also be carefully inspected for abnormalities. Since ultrasound can only indicate the presence of urinary tract malformations but cannot make an effective specific diagnosis or provide the cause, it is recommended that when performing ultrasound screening on fetuses with megacystis, changes in the megacystis and changes in the amount of amniotic fluid should be monitored dynamically and persistently, as these indicators may indicate fetal renal abnormalities and poor prognosis.
