Flash pulmonary edema (FPE) is a rare clinical presentation of renal artery stenosis. It is an episode of abrupt onset pulmonary edema that resolves rapidly. It occurs in patients with bilateral renal artery stenosis or unilateral renal artery stenosis with a solitary functioning kidney. We report a patient of diabetic end-stage renal disease on maintenance hemodialysis who manifested FPE on a few occasions which responded to renal revascularization. The indications of renal revascularization have been narrowed to poor blood pressure control, when progressive loss of renal function is encountered, or when circulatory congestion is a prominent feature.
