Acute Page kidney phenomenon: a cause of reversible renal allograft failure.

We have reported a case of reversible acute renal transplant failure due to the Page kidney phenomenon, which followed routine diagnostic needle biopsy. Duplex Doppler ultrasonography differentiated between allograft rejection and graft failure due to perirenal and mechanical abnormalities. Renal transplant failure may result from intrinsic or extrinsic allograft compression. If this is detected and treated rapidly, renal deterioration may be reversed and the transplant salvaged.
