Possible diseases with purulent discharge from the female urethra: i. Purulent urethritis, commonly caused by non-specific bacterial infections such as Escherichia coli or Staphylococcus aureus infection. This can occur with purulent discharge, accompanied by frequent urination, urinary urgency, and painful urination. Mostly, the infection is caused by local contamination, or a decrease in autoimmunity, and rarely by external factors. Local bacterial culture, or urine bacterial culture, etc. are needed to further confirm the diagnosis. Second, specific bacterial infections, such as tuberculosis infection or gonococcal, mycoplasma, chlamydia and other infections. Mostly seen as a result of contact infection, such as unclean sexual contact leading to related pathogenic bacteria infection, infection can be accompanied by purulent discharge, accompanied by burning, itching and other symptoms in the urethra. The patient has had unclean sexual contact, or has been exposed to relevant contaminants, etc. In this case, culture examination of relevant discharge, such as gonococcal culture or mycoplasma and chlamydia culture, antacid bacillus staining of urine, etc., is needed to further clarify the cause and then take symptomatic medication.
