Men with pus flowing from the lower side and stinging urine are advised to take cephalosporins mainly. In this case, the possibility of gonorrhea and non-gonorrhea should be fully considered. It is recommended to take the discharge and look for mycoplasma, chlamydia and gonococcus in the discharge for examination. If there is pus, gonococcal infection is most likely. If the gonococcal test is positive, it is recommended to give ceftriaxone sodium 2g intravenously once a day for 3 days for effective treatment. In case of pus flow, it is not excluded that there is also non-gonorrhea infection. It is recommended to use azithromycin 0.5g intravenous drip once a day for 5-7 days to achieve effective treatment. During the treatment period, you should drink more water and urinate more often. If there is a spouse and sexual intercourse, the couple should be examined and treated at the same time.
