Pseudorejection: the Page kidney phenomenon in renal allografts.

AbstractA case of renal allograft pseudorejection owing to perinephric hematoma is presented and the Page kidney phenomenon is discussed as the pathophysiologic mechanism. The term pseudorejection is introduced and defined as a remediable form of graft dysfunction resulting from renal parenchymal compression. Sonography was helpful, in addition to the standard diagnostic modalities in making the diagnosis. Early recognition and decompression of a peritransplant hematoma or lymphocele may decrease graft loss from this insidious entity.
