title: The radiological evaluation of intersex: technique of demonstrating Müllerian duct remnants in difficult cases.
abstract: In most children born with ambiguous external genitalia urethrography by the flush or catheter technique demonstrates the presence or absence of mullerian duct remnants and allows the appropriate operation to be planned according to the size and development of these remnants. However, in some cases a combined endoscopic and radiographic technique with deliberate retrograde catheterization of the vagina is mandatory. Three illustrative cases are presented.
