Surgeons can lengthen the urethra and attach it to the female urethra so that urine will flow from the tip of the penis. The female urethra is shorter than the male urethra. Skin grafts are then taken from inconspicuous areas of the body, where they will leave no visible scars, and grafted on to the donation site. The larger tube is basically rolled up around the inside tube. This tissue is used to make both the urethra and the shaft of the penis, in a tube-within-a-tube structure. They might remove this flap entirely or leave it partially attached.
During a phalloplasty, doctors remove a flap of skin from a donor area of your body.
