Bladder Exstrophy

This male infant was born with bladder exstrophy. The bladder mucosa is everted and lies on the abdomen. Both ureteric orifices lie on the exstrophic bladder. Notice that the penis is shortened and that there is no urethral meatus. His urethra is actually a plate of deep red mucosa lying on the dorsal penis. This is called epispadias.

His bladder was closed by inverting the bladder plate and sewing it closed into a sphere. Later, his urethra will be reconstructed.
