Mucus or purulent secretions from the urethra

Introduction Refers to the clinical manifestations of urethritis, and secretion smears and cultures can not detect a genitourinary system infectious disease of Neisseria gonorrhoeae. Because female patients not only have urinary tract inflammation, but also cervical inflammation, it is also called "non-specific reproductive tract infection (NSGI). It is mainly caused by infection with Chlamydia trachomatis or Ureaplasma urealyticum, and a few can also be caused by Trichomonas vaginalis. Caused by Candida albicans and herpes simplex virus, etc. It is one of the common sexually transmitted diseases.

Cause

40% to 50% of non-gonococcal urethritis is caused by Chlamydia trachomatis. Chlamydia is an intracellular parasitic microorganism between bacteria and virus, with a diameter of 250-500 nm. It has been detected by micro-immunofluorescence to detect at least 15 serotypes of Chlamydia, of which type 8 (D, E, F, G, H, 1, J, K) have been shown to be associated with urethritis. Chlamydia is not heat-resistant, rapidly loses its infectivity at room temperature, and can be killed at 50 ° C for 30 minutes. 30% of non-gonococcal urethritis is caused by urea-decomposing mycoplasma. The urea-decomposing mycoplasma is extremely tiny in the shape of a club with a diameter of only 200 nm. It is often parasitic on the human urethral epithelium and has the property of decomposing urea into ammonia. Can live independently outside the cell and have weak resistance to the external environment. It can be killed in 15 minutes at 45 °C. 10% to 20% of non-gonococcal urethritis can be caused by other pathogens. Such as trichomoniasis, Candida albicans, herpes virus, Escherichia coli, Streptococcus, Staphylococcus aureus, human papillomavirus, yeast, anaerobic Gram-negative bacilli and the like.

Urethral purulent discharge

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.

Urethral mucus secretion: mucus secretion in the urethra 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.

Differential diagnosis

There are erythema and edema in the urethra: repeated episodes of Candida balanitis appear as erythema at the glans, and there may be small pustules or small papules on the surface. It can also be expressed as local edema of the glans mucosa, mild desquamation at the edges, and the presence of papules and small pustules to expand around to form glans erosion.

Urethral effluent secretion: refers to the clinical manifestations of urethritis, and secretion smears and culture can not detect a genitourinary system infectious disease of Neisseria gonorrhoeae. Because female patients not only have urinary tract inflammation, but also cervical inflammation, it is also called "non-specific reproductive tract infection (NSGI). It is mainly caused by infection with Chlamydia trachomatis or Ureaplasma urealyticum, and a few can also be caused by Trichomonas vaginalis. Can be caused by Candida albicans and herpes simplex virus. It is one of the common sexually transmitted diseases. The incubation period is 1 to 3 weeks on average. Male patients present with urethritis, often with dysuria or urethral secretions. The degree of dysuria is lighter than gonorrhea. Sometimes it only manifests as tingling and itching of the urethra. Urethral secretions are often serous or mucopurulent, thinner and less abundant. Female patients have urinary tract symptoms such as urinary urgency and dysuria, but mainly in the cervix. Membrane. The cervix has congestion, edema, easy bleeding, yellow mucus purulent secretions, and lower abdominal discomfort. However, a considerable number of patients have mild or no clinical symptoms.

Urethral bleeding: that is, we often say hematuria, the cause of hematuria can be analyzed from whether it is accompanied by other symptoms. Asymptomatic hematuria should first consider the possibility of urinary tumors. Hematuria with pain, especially with colic, should consider urinary calculi, such as accompanied by dysuria and interruption of urinary flow, should consider bladder stones, such as with obvious bladder irritation, urinary tract infection, urinary tract tuberculosis and Bladder tumors are common. In addition, the cause of hematuria should be comprehensively judged based on the patient's medical history, age, color and degree of hematuria.

Nodular or red hemorrhagic mass in the urethra: early symptoms of paraurethral adenocarcinoma are dysuria, urethral bleeding, frequent urination, and dysuria. A nodular or red hemorrhagic mass appears in the distal urethra or urethra, and local swelling of the urethra can reach the mass. When the tumor is enlarged, it can block the urethra or expand into the vestibular vestibule and vaginal opening, and there are obvious ulcers and hemorrhagic masses, accompanied by pain and possible metastasis of the groin and pelvic lymph nodes.
