What Is Bladder Exstrophy?

To understand what bladder exstrophy is, it is important to know something about the bladder. The bladder is a muscle sac in the pelvis that stores urine. Urine is made in the kidneys. The urine travels to the bladder down two tubes called ureters. When the bladder is full of urine, the bladder muscle squeezes the urine out of the body.

Bladder exstrophy is a complicated, rare condition that occurs before a child is born. As the bladder is developing, it forms outside the child’s belly. The word “exstrophy” means “outside.”
