Urinary sediment epithelial cells

Epithelial cells seen in the urine are gently detached from the renal tubules, renal pelvis, ureter, bladder, urethra, etc. The renal tubules are cubic epithelium and can appear in the urine when the renal parenchyma is damaged. The renal pelvis, ureter, bladder and the like cover the transitional epithelial cells. The urethra is a pseudo-stratified columnar epithelial cell, and the proximal urethra is covered by the retinoic epithelial cells. When there are lesions in these areas, the corresponding increase in epithelial cells occurs in the urine. Prostate cells are occasionally seen in male urine. 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. Women who are not suitable for menstrual periods are not suitable for this examination. Microscopy should be performed promptly after urine collection, otherwise it will affect the accuracy of the test. Normal value Less or less. (Note the specific reference value depends on each laboratory.) Clinical significance Abnormal result (a) Flat squamous epithelial cells (Parementepithelial cells) from the surface of the lower ureter, bladder, urethra and vagina. It is common to save such cells in normal urine. When a large number of cells appear, it means that there is an inflammatory lesion in the urethra. (B) Renal tubular epithelial cells (Renaltubularepithelialcell) from the renal tubules, no abnormal or occasional in normal urine, the most common in acute glomerulonephritis. When the pile appears, it means that the renal tubule has a necrotic lesion. Within 1 week after kidney transplantation, more renal tubular epithelial cells can be found in the urine, which can then be gradually reduced to normal. When a decoupling reaction occurs, a piece of tubular epithelial cells can reappear in the urine. (C) Transitional epithelial cells are derived from the migration of epithelial cells from the renal pelvis, ureter, bladder and urethra near the bladder segment. 1. When the surface layer migrates to the epithelial cell cystitis, it can fall off into pieces. 2, middle-level transitional epithelial cells (kidney epithelial cells) This kind of cells are mostly from the ureter and bladder neck. When there is inflammation in the above part, it can appear in pieces. 3. The bottom layer migrates epithelial cells. Person who needs to be tested Hematuria, proteinuria, dysuria, frequent urination. High results may be diseases: acute glomerulonephritis, cystitis precautions Before the test: prohibit strenuous exercise, heavy physical labor, stop taking diuretics, amphotericin B and other drugs. At the time of examination: microscopy should be performed quickly after urine collection, otherwise the placement time is too long, if it is low urine, hemolysis can occur; if it is high urine, it may be dehydrated and the shape of red blood cells changes; if it is alkaline urine It can cause blood cell components and tube types to collapse, affecting the accuracy of the test. Inspection process The urine of the examinee was collected and examined by microscopy. Not suitable for the crowd Not suitable for the crowd: women in the menstrual period. Adverse reactions and risks No.
