Urine microscopy
This inspection is routine urine in one of the important projects. Urine contains some of the naked eye can not see the tiny structure, and a small number. In order to find the possible cause of these things trouble the urinary system, we can only use microscope to observe them, and that is urine microscopy. To discover more, usually urine centrifuge, which will be visible from the composition of precipitation, so that people can more focused discovery and observation, collecting urine specimens at least 20 ml.
Urine microscopy [alias]
[Reference]
WBC (WBC) 0-5 / HPF
Red blood cell (RBC) 0 - 3 / HPF
Transparent tube type: in the morning urine occasionally 0 - 1 / low magnification
[Clinical significance] under normal circumstances, urine should not contain or above and a small number of cells and type, also may be found in certain diagnostic value of the epithelial cells and recrystallization.
1. Increase in the number of leukocytes: Tips may be suffering from urinary tract inflammation such as urinary tract infection, pyelonephritis, cystitis, urethritis, in addition to many other diseases affecting renal function, it will increase in the number of leukocytes in urine. Female patients often mixed with vaginal secretions and urine mixed with a large number of flat epithelial cells, the female patients without any symptoms in many cases appears in the urine may be more fine white
Cellular, should be asked again at the middle of a clean urine routine inspections to eliminate interference.
2. Increase in the number of red blood cells: too many red blood cells can be described as a microscopic hematuria, now that patients may be suffering from acute glomerulonephritis, chronic glomerulonephritis, renal tuberculosis, kidney stones, kidney tumor, pyelonephritis, Acute bladder go far. Female patients should avoid menstrual period check urine, especially in the period before or after the past few days, there may be more red blood cells, the living rational, attention should be excluded.
3, tubular epithelial cells: In the absence of normal urine renal tubular epithelial cells in the urine and there may be more acute tubular necrosis, kidney transplant rejection and the interstitial nephritis. If excessive urinary epithelial cell adhesion bacteria, the diagnosis of urinary tract infection helpful.
4. Type: in a tubular, and after the deposition of protein from different cells or parcels and other substances formed by the bar, known as type, the type can be wrapped in red blood cells, white blood cell, hemoglobin, particle size, fat, epithelial cells of different ingredients. Of the following types of kidney disease and the emergence of closely related.
(1) transparent tube type: normal may occasionally, but there is more at the proteinuria in the patients with renal diseases common.
(2) particle type: found in acute and chronic glomerulonephritis, pyelonephritis, the rejection after renal transplantation period.
(3) red blood cell type: hematuria from the renal parenchyma that is common in acute glomerulonephritis, rapidly progressive, such as glomerular nephritis.
(4) interleukin type: Tips often have renal parenchyma bacterial infections, such as acute pyelonephritis.
(5) epithelial cell type: found in acute tubular necrosis, renal amyloidosis, heavy metal poisoning or chemical poisoning, also found glomerulonephritis.
(6) wax-like type: long-term renal or urinary obstruction caused by common in advanced renal insufficiency or renal starch change.
(7) Type of fat: are more transparent tube-type and particle type is more important value, was particularly prevalent in the nephropathy, lipoid nephropathy.
(8) large type: extreme renal failure, urine output is low and there.
5. Crystallization: various chemical substances in the urine of drugs and the crystallization of a help doctors and clinical diagnosis. A pathological significance is the crystallization of cystine crystal, leucine crystallization of uric acid salt crystallization and sulfa recrystallization. The emergence of some crystal stones also contribute to the diagnosis and analysis.
