A drop of pus can be squeezed out of the urethra, indicating the presence of urethral inflammation. The gonococcus is a purulent bacterium, and the human urethral mucosa is a good host for it. It is usually transmitted through impure sex, and patients usually have a history of impure sex a week before symptoms appear. In addition to causing increased purulent discharge from the urethra, it also causes a series of symptoms such as stinging urination and swelling of the penis. For urethral inflammation caused by gonococcal infection, it is necessary to go to the urology department for relevant tests to clarify the diagnosis. Usually a smear of urethral secretions can be done to look for gram-positive diplococci, or a pcr test can be done to clarify the diagnosis. Cephalosporins or quinolones are usually used for UTIs caused by gonococcal infections.
