Acute renal failure is one of the most common symptoms of the disease, acute renal failure is a clinical syndrome with multiple etiological factors, is the sudden loss of renal function leads to changes of renal circulatory failure or renal tubule, and can cause accumulation of toxins, waste and water. Acute renal failure need to do what checks? How to diagnose? The following experts on the diagnosis of acute renal failure principles and methods were introduced, together to understand the next bar.
What are the diagnostic principles of acute renal failure?
Originally, chronic kidney disease, due to the deterioration of renal function and acute renal failure. The reason may progress to chronic kidney original speed (immune injury such as persistent progressive renal damage) or a sudden increase in risk factors (such as infection, urinary tract obstruction, the use of nephrotoxic drugs, high protein diet, hypercalcemia, hyperuricemia and blood pressure increased sharply).
Two. Many causes of acute renal failure can be divided into pre renal acute renal failure, renal parenchymal acute renal failure and post renal acute renal failure. The classification of the only representative of the cause of disease at diagnosis, some patients with acute renal failure may be caused by a variety of reasons, some patients is difficult to go to a class, and in the development of the disease can be converted to prerenal renal parenchymal acute renal failure, post renal acute renal failure as is not a long time the treatment can be converted to chronic renal failure.
In the process of diagnosis, the general should first identify whether the acute exacerbation of chronic renal insufficiency, and then according to the order of differential or post acute renal failure or prerenal acute renal failure, and finally for the differential diagnosis of renal parenchymal diseases one by one.
What are the methods of diagnosing acute renal failure?
(1) examination of urinary sediment.
(2) renal biopsy for renal parenchymal ARF is not clear, is a diagnostic method.
(3) imaging including B Ultrasound, kidney area medical education network collected ` abdominal plain film, CT, urography and radionuclide scan.
(4) urine diagnostic indicators including urine specific gravity, urinary osmolality, urinary sodium, renal failure index and sodium excretion fraction were significant for the identification of pre renal interstitial blood disease and atn.
