Urinary 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: The drugs that increase the number of granules are amphotericin B, kanamycin, bismuth, calcitonin, indomethacin and so on. Normal value 0 ~ Occasionally transparent tube type. (high power field of view) Clinical significance (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. (7) waxy, tubular type suggests that the local nephron has long-term obstruction, and now there is oliguria or anuria. It is seen in severe glomerulonephritis, advanced chronic nephritis, chronic renal failure, etc., often with poor prognosis. (8) Hemoglobin cast is found in acute hemorrhagic nephritis and hemoglobinuria. (9) The mixed tube type is a mixture of various cell components, which can be seen in the late stage of nephritis and interstitial disease of the tubule. High results may be diseases: glomerulonephritis, nephrotic syndrome precautions (1) The transparent tube type is occasionally seen in normal urine, and the transparent tube type can also be seen under severe exercise, heavy physical labor, anesthesia and high heat. In addition, taking diuretics, amphotericin B and other drugs can increase the transparent tube type of urine. (2) Drugs that increase the number of granules are amphotericin B, kanamycin, bismuth, calcitonin, indomethacin and the like. Inspection process Add a drop of dye solution to 0.2 ml of urine sediment and mix and dye. After 3 minutes, take the sediment cover and take a slide of the slide. Not suitable for the crowd Generally no taboos. Adverse reactions and risks No.
