Legally, there is nothing wrong with getting married while you are in the U.S. as a visitor (on a B-2 visa) , if you return home at the end of your permitted stay. But that doesn't mean this is a risk-free strategy.
Vaginal Prolapse (aka vault prolapse). If the uterus has been removed, apical prolapse may still occur if the supports at the top of the vagina tear or become weak. In this case the top of the vagina (and often small bowel as well, ie enterocele), fall toward the introitus.
It is where the uterus (womb) drops down into the vagina. Uterine prolapse is caused by weakening of the muscles (pelvic floor muscles) and ligaments that usually support the uterus and keep it in place. Occasionally other internal organs like the bladder, urethra, rectum or part of the intestines can bulge into the vagina for the same reason.
