Urine sediment casts

Urine sediment tube type inspection is one of the contents of urine sediment inspection. The tube type is formed by aggregation of proteins in the renal tubules. The appearance of urine is generally evidence of renal parenchymal lesions. In the process of its formation, if it contains cells, it is a cell tube type; if it contains degenerative cell debris, It is a granular tube type; if it contains fat droplets, it is a fat tube type. Basic Information Specialist classification: urinary examination classification: urine / kidney function test Applicable gender: whether men and women apply fasting: fasting Tips: Do not exercise vigorously, heavy physical labor, stop taking diuretics, amphotericin B and other drugs. Normal value 0 to occasionally transparent tube type (high power field). Clinical significance Abnormal result (1) When a large number of transparent tube types appear, they are found in acute glomerulonephritis, acute pyelonephritis, interstitial nephritis, malignant hypertension, congestive heart failure and renal arteriosclerosis. (2) Granular casts are common in various glomerular diseases, such as acute glomerulonephritis, acute pyelonephritis, rejection after renal transplantation, renal tubular poisoning, viral infection, chronic lead poisoning, malignant hypertension, amyloidosis And obstructive jaundice and so on. (3) erythrocyte cast type suggesting glomerular hemorrhage, seen in acute glomerulonephritis, acute renal tubular hemorrhagic necrosis, acute exacerbation of chronic nephritis, lupus nephropathy, IgA nephropathy, renal infarction, rejection after renal transplantation. (4) Leukocyte cast type suggests that the kidney has bacterial inflammation, found in acute pyelonephritis, interstitial nephritis, nephrotic syndrome. If the white blood cells become pus cells, called pus tube cast, seen in suppurative inflammation. (5) Tubular epithelial cell casts are found in gestational eclampsia, renal amyloidosis, renal transplant rejection, acute tubular necrosis caused by heavy metals or drug poisoning. (6) fat tube type is more common in nephrotic syndrome, chronic glomerulonephritis, acute exacerbation of chronic nephritis, toxic nephropathy. People who need to be tested for abnormal kidney function. High results may be diseases: acute pyelonephritis, acute glomerulonephritis, nephritis, nephrotic syndrome Before the test: prohibit strenuous exercise, heavy physical labor, stop taking diuretics, amphotericin B and other drugs. When checking: Relax your body and eliminate tension and anxiety. Inspection process 1. Collection of specimens: Keep fresh urine 100~200 ml at any time with a clean container, preferably with the first urine in the morning. Adult women should avoid menstrual and vaginal discharge into the urine when they are taken. If it cannot be sent immediately, it should be stored in the refrigerator first. 2. Urine routine examination includes general urinary properties, chemical composition and sedimentation examination of urine. Normal urine is about 1500~2000 ml per day for adults. The color is light yellow, transparent and slightly ammonia smell. The urine specific gravity is about 1.010~1.025. If there is a urinary tract infection, the urine will become cloudy and stench, and the urine of diabetics will have a rotten apple flavor. Acute nephritis, hyperthermia, dehydration, diabetes, etc. have a small amount of urine and a high proportion; the proportion of urine in the late stage of chronic nephritis is often below 1.010. 3, normal urine showed weak acidity, urine sugar and urine protein were negative. 4, urine sediment microscopy, including cell components (red blood cells, white blood cells), tube type, salt crystals. There are a lot of white blood cells in the urine to indicate inflammation in the urinary system; there are a lot of red blood cells to indicate hematuria, which is common in stones, tuberculosis and tumors; there is a tube type in the urine, indicating that there is organic disease in the kidney; if there is a large amount of calcium oxalate crystal, it means there is The possibility of urinary tract stones. Not suitable for the crowd Generally no taboos. Adverse reactions and risks No.
