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.
在胶原病病程中很少观察到输尿管病变，一旦发生，这些病变是这些疾病的特定局部表现。诊断通过静脉尿路造影进行。这通常显示单侧或双侧节段性狭窄，可能伴有钙化，病变最常出现在腰部区域。在罕见情况下，会出现“珍珠项链”型扩张。狭窄通常会加重，尤其是在皮质激素治疗减量时，可能需要切除受影响的输尿管节段。
