Diagnosis of uremia
Blood urea nitrogen and creatinine increased. Hemoglobin is generally below 80g/L, the final stage can be reduced to 20-30g/L, may be associated with thrombocytopenia or high white blood cells. Arterial blood gas and acid and alkali were measured. The pH value decreased, AB, SB and BE decreased in the late stage, and the PaCO2 was decreased. The plasma protein may be normal or reduced. The determination of abnormal electrolyte.
Two, urine examination urine routine change can vary according to the underlying cause, can have proteinuria, red, white blood cell or tube type, also can change not obvious. Second, the proportion of urine is more than 1.018, when uremia is fixed at 1.010~1.012, the amount of urine at night is more than that of daytime urine.
Three. Renal function test showed that glomerular filtration rate and creatinine clearance rate decreased. The phenolsulfonphthalein excretion test and urine concentration and dilution test were all decreased. Determination of pure water clearance. The radionuclide imaging scan, renal scintigraphy and also contribute to the understanding of renal function. Four, other urinary system examination of X-ray plain film or angiography, renal biopsy, contribute to the cause of disease diagnosis. According to the diagnosis of chronic kidney disease, clinical manifestations and urine, blood biochemical examination, can be diagnosed. According to the degree of abnormal renal glomerular filtration rate (GFR), blood urea nitrogen (BUN) and serum creatinine (CR) level is pided into three phases: one, renal insufficiency compensatory period between GFR 50-70ml/min, BuN 8.93mmol/L 7.14 "blood", "blood Cr 132177umol/L, mild fatigue, anorexia and eating different degrees of anemia and other symptoms.
Four, uremia period GFR21.42mmol/L, blood Cr, 442umol/L, has obvious clinical symptoms of uremia. Such as GFR
