title: Ureteroileocancerous backflow: a diagnostic radiographic sign for metastatic carcinoma.
abstract: Ureteroileocancerous backflow is a radiographic finding representing extravasation of contrast material into venous sinuses of periureteral cancerous tissues. It is suggested that this finding, which has heretofore been undescribed, is diagnostic of recurrent malignancy and that patients may be spared secondary surgical procedures for confirmation of recurrent tumor.
