Fused labia. Clinical and radiological findings.

The clinical and radiological findings in fused labia are described. Some of the patients were asymptomatic. The others were referred because of a suspicion of urinary infection. Micturating cystourethrography showed collection of contrast material above the labia and marked reflux into the vagina in all patients examined. These findings were not seen after separation of the labia. Although the diagnosis is usually a clinical one, it is suggested that labial fusion may first be recognized by the radiologist through these cystourethrographic findings and while catheterizing the child.
