When pain occurs at the end of urination, inflammation of the posterior urethra or inflammation of the bladder neck is most often considered. In this case, local smooth muscle contraction can occur after urination and produce throbbing pain, which can disappear after a few moments of relief and can still occur after the next urination. Some patients may experience cloudy urine in the posterior segment after urination, or may experience blood in the eyes at the end of urination, both of which are inflammation of the posterior urethra and inflammation of the bladder neck. For treatment, it is recommended to retain urine for routine urine or urine culture examination and select sensitive antibiotics for anti-infection treatment according to the examination results. Commonly used drugs such as ciprofloxacin tablets, 1 tablet each time, 3 times a day; levofloxacin capsules, 1 capsule each time, 3 times a day, 7 days of continuous oral intake, even if the symptoms are relieved, it is recommended to finish the 7-day total course of treatment to avoid incomplete treatment and cause recurrent attacks.
