When should the urinary bladder be visible on Ultrasound

When should the urinary bladder be visible on Ultrasound?

By 16 weeks gestation, the bladder should be visible sonographically. As the bladder may normally fill and empty during the course of a routine second trimester US, if the bladder is not first visualized, repeat US imaging should be performed every 15 to 20 minutes for 1 hour before determining that the bladder is nonvisible.

If the bladder is still not seen after 1 hour of reimaging, nonvisualization may be due to bilateral intrinsic renal impairment, upper urinary tract obstruction, bladder exstrophy, or a systemic cause such as IUGR. Bladder exstrophy is associated with an infraumbilical wall defect.
