Cloacal Abnormalities

As a baby develops, three openings normally form for the intestinal, genital and urinary tracts. In early stages of pregnancy, these three openings are together in a sac called "Cloaca." They then separate from each other to form the anus, vagina and urethra. In rare cases, this area may develop incorrectly. A "persistent cloaca" may form if these tracts fail to separate from each other. This is when the intestinal, genital and urinary tracts open into one common cavity, with one opening on the skin where the vaginal opening would be. A newborn with this defect has no visible anus (the opening where feces leave the body). Everything else on the outside usually looks normal. Cloacal anomalies can affect 1 in every 50,000 babies.

Overview

In some cases the three tracts come together at a low point close to the skin. Since it is close to the skin, the "common channel" is short. These girls usually pass urine without problems.

In more severe cases the three tracts come together at a high point. Thus, the common channel is long, so draining urine and feces is more difficult. Urinary tract infections are common.
