| • The dilated sac-like structure in the center of the
photograph is a persistent cloaca. There has been
failure in early fetal life of the urorectal septum to
divide the rectum from the urogenital sinus.
• The photograph is a posterior view. Entering the
cloaca are the colon, the right ureter and the
left ureter (not shown). The cloaca served as
rectum and bladder. There was no left kidney
(renal agenesis). The infant had no anus.
• The only outlet was a thin narrow urethra. |
