Male reproductive system
Irregularities of the urethra in young boys are rare. But they can cause problems with urination.
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 entire penis. 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.
