[Urachal malformation. Clinical and radiological findings in one case (author's transl)]

An exceptional case of patient urachus, reported on a 54 year-old man, has led the authors to make an up-to-date survey on this malformative pathology. 4 types can be individualized, for which the roentgen diagnosis is quite simple (intravenous urography ultrasonography, fistulography). The risk of malignant degeneration obliges, after the search for other associated malformations, surgical cure and anatomo-pathologic verification.
