Learning Objectives
Evaluation of the fetal urinary bladder is important to detect the associated anomalies of urinary tract and other fetal organs.
We have experienced many cases of urinary tract anomalies associated with normal and abnormal feature of urinary bladder.
The purposes of this exhibition are to suggest a systematic evaluation of the fetal urinary bladder and to review the radiological findings of variable conditions of fetal urinary bladder and associated anomalies.
Background
Evaluation of the fetal urinary bladder is important to detect the associated anomalies of urinary tract and other fetal organs.
Imaging Findings OR Procedure Details
Normal Urinary Bladder
The fetal urinary bladder is well visualized during the 1st trimester.
In many instance,
however,
the bladder is not visualized during the US exam without definite abnormality
Although the fetus normally fills and empties bladder every 30 to 45 minutes, urinary bladder is visualized during the US exam in the 2nd and 3rd trimester
The bladder wall is very thin and located in the central pelvis.
Bilateral internal iliac arteries run around the bladder and branch the umbilical arteries,
which is the...
Conclusion
Evaluation of the fetal urinary bladder is important to detect the associated anomalies of urinary tract and other fetal organs
