Spontaneous Reversal of Renal Failure by Renal Artery Recanalization

Abstract

• The kidney can remain viable even in anuric renal failure. Arteriography and hippuran scanning were not helpful in determining renal viability in a 41-year-old man. Interestingly, a high-grade stenotic lesion of the renal artery had resolved during a three-month period probably by recanalization. This illustrates that conservative management may result in preservation of viable renal parenchyma. (Arch Surg 116:107-109, 1981)
