What is the cause of blood in urine, how to do?

Urinary tingling and bleeding may be related to urethral trauma, urethritis, urethral calculi and other factors, which need to be treated in combination with specific causes, as follows: 1. Urinary trauma: The patient has urethral mucosa damage caused by riding injury, repeated urinary catheter insertion and other factors, and urine discharge stimulates the wound, thus causing urinary tingling and bleeding. Patients need to stay in bed and reduce exercise to facilitate wound healing. If the pain is severe and accompanied by infection, ibuprofen, diclofenac, cefixime and other drugs can be prescribed to control local infection and relieve urinary tingling. 2. Urethritis: Urethritis caused by Neisseria gonorrhoeae, Chlamydia trachomatis and other pathogens, urethral mucosa is stimulated by inflammation, and congestion, rupture and bleeding occur; urine excretion stimulates damaged parts, resulting in tingling and bleeding in urine. The patient should be treated with ceftriaxone, tetracycline, metronidazole and other drugs according to medical advice, so as to relieve tingling and bleeding in urine. 3. Urethral stones: urethral stones cause damage to urethral mucosa due to stones, causing local bleeding; urine stimulates the wound during urination, resulting in tingling and bleeding in urine. Patients can remove stones by surgery, thereby reducing the damage to urethra caused by stones and alleviating the symptoms of tingling and bleeding in urine. Patients should drink more water and adjust their diet according to the stone composition to reduce the probability of suffering from urethral stones again.
