Burning and Bleeding After Urination




Bleeding at the end of the urinary stream.


Antibiotics are appropriate if the bleeding and burning are caused by a urinary tract infection. Some urinary infections, including bladder infections, prostate infections, and urethritis (inflammation of the urethra, the tube in the penis that leads from the bladder to the outside), can lead to blood in the urine or at the tip of the urethra. Recurrence of this symptom should make the treating physician suspicious that either the bleeding is not due to an infection, the infection was incompletely treated, or the same or another organism has caused a recurrent infection.


Appropriate use of cultures (placing some urine in a culture dish in the lab to see whether organisms grow — and if so, what kind) to guide antibiotic therapy is the best way to completely eradicate a urinary tract infection. If in fact you did not have a documented culture-positive infection, then other causes of hematuria need to be investigated.


These can include a kidney stone that passed down into the bladder or urethra; a tumor of the bladder, urethra, or upper urinary tract; and a vascular (blood vessel) malformation. These potential sources of blood should be investigated. The most common cause of bleeding in the urinary tract in men is enlargement of the prostate, but this is a diagnosis of exclusion that can only be entertained when more serious causes have been ruled out.
