How is congenital absence of uterus and vagina treated?

Patient's question:

At 18, still no menstruation was found

Doctor's answer:

When necessary, vaginoplasty can be performed to address sexual intercourse issues.
Vaginoplasty: A transverse incision is made at the location corresponding to the external vaginal orifice. The tissue between the urethra-bladder and rectum is bluntly separated to create a space approximately 10 cm deep and 3-4 cm in diameter. Then, a vaginal mold covered with amnion or a skin graft is inserted into the newly formed artificial vagina.
One week later, the vaginal mold is replaced. The mold is typically made of glass, plastic, or wood, measuring 9-11 cm in length and 3-3.5 cm in diameter. It is generally left in place for one year. Starting from the sixth month, the mold is removed for 1-2 hours daily, with the removal time gradually increasing thereafter.
If the surgery is performed after marriage, sexual intercourse can begin once the vaginal epithelium has grown well and the tissues have become soft. At this point, the nighttime insertion time can be appropriately shortened.
After surgery, if sexual intercourse is abstained from for an extended period, the vaginal mold must still be used to prevent adhesion and vaginal stenosis.
