Abstract
Uremic lung or uremic pneumopathy is the characteristic radiologic picture of the so-called "batwing" distribution of increased density in the chest film in patients with uremia. It is attibuted to the pulmonary overhydration and/or increased capillary permeability. Although this roentogenological term is known since fairly old time. it is rather rare to see this picture in clinical medicine of renal failure. We experinced two successive occurence of this shadow in one case of chronic renal failure during the conservative treament. These abnormal shadows disappeared completely soon after the treatment with regular hemodialysis. The course and nature of uremic lung of this case was reported precisely in this paper.
