[Ureteral manifestations of collagen diseases (author's transl)].

Ureteral lesions are rarely observed during the course of collagen diseases, and when they do occur, are specific localizations of these disorders. Diagnosis is made by intravenous urography. This usually demonstrates uni- or bi-lateral segmentary stenoses that may be calcified, with the lesions being most frequently present in the lumbar region. In rare cases there is dilatation of the "necklace of pearls" type. The stenosis usually increases in severity, especially when corticotherapy is reduced, and resection of the affected ureteral segments may be necessary.
