Urethral infection is a common disease among male friends. The main reasons for male friends to form urinary tract infection are that they sit for a long time, hold their urine, reduce their resistance, and have prostatitis and other diseases, which are easy to cause urinary tract blockage, thus causing bacterial reproduction and infection. At the same time, when the patient's resistance is reduced or the urethral mucosa is slightly damaged, or the bacteria are highly toxic and have strong ability to adhere to the urethral mucosa and ascend, it is also easy to invade the bladder and kidney, which will cause infection. For patients, they can be treated by using drugs, such as erythromycin, azithromycin and other drugs. Patients must drink more water and discharge more frequently at ordinary times, which is conducive to the recovery of the disease. The above scheme is only for reference. Please use the specific drugs under the guidance of professional doctors according to your own conditions.
