title: Renal metastases of malignant gestational trophoblastic disease: the use of intravenous urography in staging.
abstract: Intravenous urography (IVU) was performed in 289 patients at the time of diagnosis of malignant gestational trophoblastic disease (GTD). Ninety-five percent of these studies were normal, and none of the urologic abnormalities detected provoked alteration of the patients' tumor-related therapy. In the detection of renal metastases, false-positive and false-negative intravenous urograms were encountered. It is concluded that IVU lacks sufficient sensitivity and specificity in the detection of renal metastatic GTD; alternate screening methods are recommended.
