The urethra is a vital part of the urinary tract. Its main job is to carry urine out of the body. In men, this channel also carries semen from the reproductive tract. Most people won't have problems with the urethra, but a few of us may suffer from benign (no cancer) urethral lesions.

What Happens under Normal Conditions?

The urethra is a tube-like organ that carries urine from the bladder out of the body. In males, the urethra starts at the bladder and runs through the prostate gland, perineum (the space between the scrotum and the anus), and the penis. In women, the urethra is much shorter: it runs from the bladder to just in front of the vagina and opens outside the body. Normal urine flow is painless and can be controlled. The stream is strong and the urine is clear with no visible blood.

A lesion is a damaged part of an organ or tissue. The defect keeps the organ from working the way it should.

Causes

Lesions can be caused by an accident, infection, or the way the organ grows.
Some causes are:

  • abscesses
  • pelvic breaks
  • straddle injuries
  • infections
  • injury caused by medical tools (such as catheters or cystoscopes)
  • rare health problems present at birth
