Anuria secondary to renal artery obstruction in a solitary kidney: 9-year followup.

A patient with a prior nephrectomy for renovascular hypertension experienced complete anuria secondary to renal artery occlusion. Revascularization 75 hours later resulted in prompt diuresis, recovery of renal function and a 9-year survival. Serial preoperative renal function studies are presented. Deterioration of renal function and recurrent hypertension are believed to have heralded the onset of arterial obstruction to a solitary kidney. The literature concerning the etiology of renal artery occlusion and the rationale for therapy are reviewed.
