Diagnosis of Bladder Exstrophy
A diagnosis of BE is often made before to the baby’s birth with an ultrasound or MRI. Signs of this condition that may be seen on ultrasound or MRI include:

A bladder that isn’t filling or emptying correctly or completely

An umbilical cord that is lower than normal on the abdomen of the fetus

Separated pubic bones. The pubic bones are part of the hipbones, which form the pelvis.

Smaller genitals than normal

In some cases, the condition is not diagnosed until the baby is born, and diagnosis is made by looking for specific characteristics, including an open bladder and physical abnormalities in the genitals, pelvis, and abdomen.
