[New approaches to the pathogenetic therapy and prevention of acute kidney failure related to the use of x-ray contrast agents].

The authors analyze causes, mechanisms underlying acute renal failure (ARF) attributed to tests with application of radioopaque substances and results of ARF treatment in 12 ARF patients and on Wistar rats models. It is inferred that ARF is a frequent and severe complication of the above tests which may be treated successfully by early application of dialysis, filtration, sorption, plasmapheresis techniques. Disorders of calcium metabolism and their correction contribute to ARF onset. Radio-opaque substances have essential inhibiting action on nitrogen oxide synthesis in the kidneys of experimental animals.
