urethral discharge test

The urethral secretion examination is a smear examination of the secretions of the urethra and a rough diagnosis based on the corresponding secretions. Comprehensive analysis of clinical and laboratory findings of urethral secretion examination can be used for the diagnosis of non-gonococcal urethritis. Basic Information Specialist classification: urinary examination classification: biochemical examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Negative is a normal condition. Positive: Prompt there is urinary tract inflammation. Tips: In order to prevent infection, sexual partners should avoid sexual life before they are completely cured. The towels, washbasins, sheets and other infectious materials should be used strictly. The pollutants can be boiled and disinfected. Personal prevention of available condoms. Patients with severe injuries to the urethral opening or who have just completed a urethral opening are not eligible for this test. Normal value Gram staining of urethral secretions showed an average of <5 per field of view under oil mirror (1000 times), and no hemorrhage and bloody secretion of <15 polymorphonuclear leukocytes per field of view in high magnification (400 times) field of view. Substance, purulent secretions, liquid secretions, etc., are negative. Clinical significance Abnormal result Male urethral secretion Gram staining smear showed polymorphonuclear leukocytes, and ≥5 per field was positive under oil mirror (1000 times). In the morning, the first urine or urination interval of 3 to 4 hours of urine (15 ml of anterior urine) sediment in the high power microscope (400 times) field of view, the average per field of ≥ 15 polymorphonuclear leukocytes have diagnostic significance. Or male patients <60 years old, no kidney disease or bladder infection, no prostatitis or mechanical damage to the urinary tract, but those with positive urine white cell esterase test can also be diagnosed as non-gonococcal urethritis. Female cervical mucus purulent secretion, yellow, with an average of 10 lesions per field of polymorphonuclear leukocytes under oil mirror (1000 times) (but should be excluded from trichomoniasis). People who need to be examined: patients with burning pain, frequent urination and urgency or urinary fistula during urination. Positive results may be diseases: gonorrhea complication prostatitis, epididymitis, gonorrhea complicated with seminal vesiculitis, acute urethritis, acute superficial foreskin balanitis, penile head dermatitis, Reiter syndrome, fungal urethritis, vestibular gland inflammation , urinary tract cancer considerations Contraindications before examination: pay attention to rest, add enough liquid, to prevent indirect infection should be used separately, the bathroom, towels and sheets should be disinfected. In order to prevent infection, sexual partners should avoid sexual life before they are completely cured. The towels, washbasins, sheets and other infectious materials should be used strictly; the pollutants can be boiled and disinfected. Personal prevention of available condoms. Requirements for examination: If the doctor uses the urethral test strip to take the urethral secretions, if there is a burning sensation, it means that there is inflammation in the urethral orifice or the doctor takes the secretions seriously. It is necessary to inform the doctor in time so that the doctor can make the correct diagnosis and treatment or change in time. Manipulation, reduce pain. Inspection process Laboratory urethral secretion examination Smear, culture examination, evidence of no Neisseria gonorrhoeae. Male urethral secretion Gram staining smear showed polymorphonuclear leukocytes, and ≥5 per field was positive under oil mirror (1000 times). In the morning, the first urine or urination interval of 3 to 4 hours of urine (15 ml of anterior urine) sediment in the high power microscope (400 times) field of view, the average per field of ≥ 15 polymorphonuclear leukocytes have diagnostic significance. Or male patients <60 years old, no kidney disease or bladder infection, no prostatitis or mechanical damage to the urinary tract, but those with positive urine white cell esterase test can also be diagnosed as non-gonococcal urethritis. Female cervical mucus purulent secretion, yellow, with an average of 10 lesions per field of polymorphonuclear leukocytes under oil mirror (1000 times) (but should be excluded from trichomoniasis). At present, due to the unconditional or insufficient standardization of the culture and diagnostic kit for Chlamydia, it is only necessary to see inflammatory cells (polymorphonuclear leukocytes) in the clinical laboratory diagnosis and to eliminate the gonococcal infection to make a diagnosis. Transurethral secretions are examined for urethral secretions: 1, urethral bleeding Urethral bleeding refers to the involuntary overflow of blood from the urethra, and has nothing to do with urination. It can be seen that there is fresh blood spilling or dripping from the urethral opening, or there is blood in the mouth of the ten urethra. Urethral hemorrhage is often caused by urethral injury or urethral instrument application causing rupture of the urethral vascular rupture. Or found in urethra stones, urethral foreign bodies, urethral tumors, urethritis, prostatitis and urethral ulcers. 2, urethral blood secretions The urethral bloody secretion refers to the secretion of pus and blood in the urethral orifice or the secretion of blood and mucus. Urethral bloody secretions are mostly caused by urinary tract infections. More common in urethral injury, urethral stones, foreign body secondary infection, urethral tumor, urethral meat and urethritis, prostatitis, urethral obstruction such as stenosis, diverticulum, valve and so on. 3, urethral purulent secretions There is a yellow viscous secretion in the urethral opening. There are a large number of pus cells in the microscopic examination, or there is a purulent adhesion in the urethral orifice, which is called purulent discharge of the urethra. The purulent discharge of the urethra is caused by a purulent infection of the urethra. More common in prostatitis, tuberculous urethritis, gonorrhea urethritis, as well as urethral stones, foreign bodies, tumors, injuries, stenosis, diverticulum, valves and other secondary infections or indwelling catheters in the urethra, the use of equipment, the use of chemicals, another There are masturbation and so on. 4, urethral mucus secretions The urethral orifice has mucous secretions or mucus sputum attached to the urethral mucus secretion. Its performance can be turbid, milky and viscous or clear and thin. Urethral mucus secretions are more common in non-specific urethritis, fungal urethritis, chlamydia, mycoplasma, gonorrhea, trichomoniasis or virus-induced urethritis, prostatitis, prostate leakage, urethral bulbitis. Not suitable for the crowd Patients with severe injury to the urethral opening or who have just completed a urethral opening surgery are not suitable for this test because the secretions or bacterial colonies around the wound may affect the results of the examination. Adverse reactions and risks This test is a non-invasive test that does not cause sequelae or other hazards.
