Once put to sleep usually under a general anaesthetic (In some cases a local anaesthetic and sedation can be used if appropriate) your surgeon will begin your surgery.  A vaginoplasty operation typically takes about 1 - 2 hours, and is treated as a day case, meaning that you are discharged to go home a few hours after your surgery is completed.
The surgery is designed to tighten the vagina and is done by joining together the stretched muscle at the back of the vagina and therefore shortening it, using dissolvable stitches, and then removing excess vaginal lining and tightening the surrounding soft tissues.  The resulting decrease in the size of the vaginal cavity creates more friction during sexual intercourse, often described as giving a woman back the vagina she had before children.  When the muscles and ligaments in the vagina are tightened, they can then support the other internal structures including the bladder, bowel and womb (uterus).
