Although Tracey is correct, a UTI can cause bleeding from the urethra , this would be less common if you do not experience frequency of urination, urgency to void, or burning when you urinate. These are classical signs of a urinary tract infection, but are not specific for a UTI only. I would strongly recommend an office visit to a local urologist who will be able to look at your urine under the microscope for blood cells and test for infection. This is the most sensitive test to find if you have a problem of the urethra or bladder. A thorough doctor will do a pelvic exam to make sure the blood is not coming from elsewhere.
Urethral cancer is very rare but a possibility.
Small venereal warts can grow inside the urethra in men and women. From these possible diagnosis, you can see that you need a urological work-up even if the bleeding disappears. We offer the above mentioned services at Henry Ford Hospital and its urban campuses. We can also arrange local accommodations through this number if this is your need. Please bring any physicians notes and lab test results that you may be able to obtain.
