Ureaplasma urealyticum, usually referred to as Mycoplasma solani, is one of the common parasitic bacteria in the human genitourinary system and belongs to a group of mycoplasmas that can cause disease under specific circumstances. A positive Mycoplasma urealyticum in men indicates local mucosal damage and invasion of Mycoplasma urealyticum into the local mucosa, causing inflammatory changes in the genitourinary system, which can lead to diseases such as non-gonococcal urethritis, male infertility, and urinary stones. The causes of positivity mainly include high concentration of mycoplasma infection, decreased body resistance, and trauma.1. High concentration of mycoplasma infection: mainly transmitted through sexual life and contaminated clothing, mostly seen in the period of youth and high sexual desire. When inflammation occurs in the genitourinary system and the mucosal surface is damaged, Mycoplasma urealyticum easily invades from the breach and causes genitourinary system infection. When infected with Mycoplasma solium, patients will experience urethral tingling, varying degrees of urinary urgency and frequency, and stinging pain in urination. There will be mild redness and swelling at the urethral orifice, and the discharge will be thin and small. 2. Decreased resistance: A small amount of Mycoplasma urealyticum can also cause symptoms when the immunity is low. If people with low immunity come into contact with toilet lids, benches and other household items contaminated with these secretions that contain a small amount of Mycoplasma urealyticum, they may also be infected and become ill; 3. Trauma: Mycoplasma urealyticum can enter the body through wounds on the skin or mucous membranes to cause infection, and the disease will start to develop after the number of germs multiplying in the body reaches a certain level. Therefore, in order to prevent infection, the wound must be disinfected at ordinary times. If you are infected with Mycoplasma solani, you don’t need special treatment if you don’t have obvious symptoms, but you need to pay attention to avoid unclean sexual life, strengthen nutrition, and exercise properly to enhance your body resistance. Patients who already have symptoms such as urethral tingling and urinary urgency must go to a regular hospital and use clarithromycin, doxycycline and other drugs for treatment under the guidance of a doctor. Do not eat spicy and stimulating food during treatment, drink more water and pay attention to personal hygiene.
