It is recommended to go to the hospital for examination to clarify the cause of bleeding and then treat it symptomatically.1. If the bleeding from the urethra after hand trauma is relatively small, it is recommended to drink more water and urinate more for observation. If the open trauma is visible to the naked eye, suturing is needed to stop the bleeding. If the amount of bleeding is relatively large, it is recommended to leave a catheter in place. The catheter can compress the local bleeding site to reduce bleeding, while flushing can be performed to reduce bleeding. 2. If the bleeding is caused by the presence of stones, tumors and other diseases in the urethra, hospitalization is required. If the bleeding is due to acute inflammation of the urethra, anti-infection treatment is recommended according to the specific infecting bacteria, such as gonococcal urethritis, which is treated with Ceftriaxone sodium for injection. If it is a non-gonococcal UTI, it can be treated with azithromycin or roxithromycin and other drugs.
