title: Xanthogranulomatous pyelonephritis in renal transplant recipient.
abstract: Xanthogranulomatous pyelonephritis is reported in the native kidney of a renal allograft recipient. Immunoglobulin deposition in the transplant kidney in the absence of cell-mediated rejection, accompanied by selective cultures showing Escherichia coli from the native kidney, led to the diagnosis. Native nephrectomy resulted in resolution of the patient's chronic bacteriuria and creatinine elevation.
