If you have blood at the end of the penis or in the urine or can’t pass urine after an injury to the urethral area, you should see a health care provider right away.
Your health care provider may try to pass a tube ("catheter") through your urethra. Not being able to pass a tube into the urethra is the first sign of urethral injury. An x-ray is done after squirting a special dye into the urethra. The dye is used to be seen on an x-ray. X-rays are taken to see if any of the dye leaks out of the urethra inside your body. This would mean there’s an injury. An x-ray of the urethra is often done after a pelvic fracture, because urethral injury is common in these cases (about 1 in 10 cases).
