Urethritis is divided into gonococcal urethritis (commonly known as gonorrhea) and non-gonococcal urethritis, both of which are common sexually transmitted diseases that manifest with itching, burning sensation and painful urination, redness of the urethra and purulent discharge, but each has its own characteristics in terms of specific performance. Non-gonococcal urethritis is a type of disease in which urethritis is present but no gonococcus can be detected in the urethral discharge, mainly caused by Chlamydia and Mycoplasma. Non-gonococcal urethritis is transmitted through sexual intercourse and invades the urogenital tract organs. Of these, 40-50% are caused by biological variants of Chlamydia trachomatis, and 20-30% are caused by mycoplasma. The main causes of genitourinary infections are Mycoplasma solani and Mycoplasma mansoni. The incubation period of non-gonococcal urethritis is usually 7-21 days. Male patients often have tingling, burning sensation and painful urination in the urethra, and a few have a slightly red urethral opening with frequent urination. In the morning, there is a small amount of mucus discharge from the urethra or only a scabby mouth, or a dirty crotch and a bifurcation of the urine stream when urinating. Some patients need to squeeze hard with their hands to get the discharge out of the urethra. The symptoms are similar to those of gonorrheal urethritis, but to a lesser extent. Gonococcal urethritis is gonorrhea, a purulent infection of the genitourinary system caused by the bacterium Dictyococcus gonorrhoeae, and can be diagnosed by direct smear of urethral discharge for gonococci. Clinically, it can manifest as simple urethritis, with the main symptoms of frequent urination, urgent urination, painful urination and pus; it can also manifest as prostatitis, vesiculitis and pelvic inflammatory disease in addition to urethritis, with more complex symptoms such as perineal discomfort, seminal emission, painful intercourse and bloody semen. In serious cases, peritonitis and gonorrhea can occur, manifesting as high fever, abdominal pain and even life-threatening, and is one of the more dangerous STDs. If you’re not cured in time, there will be a risk of complications over time. The actual UTI is a very important part of the process, so you should go to a hospital where you can get treatment in a timely manner, and don’t hide your medical history from your doctor or abuse antibiotics on your own to avoid delaying treatment. If you are a doctor, you can get rid of the UTI by strictly following the doctor’s instructions.
