Uterine prolapse, or the dropping or sagging of the uterus (and perhaps other organs like the bladder) into the vagina is, unfortunately, a fairly common problem in women. The investigators of the Pelvic Floor Disorders Network have been very interested in comparing various treatments for prolapse in order to provide information that will help doctors develop the best treatment plan for their patients. Often, repair of uterine prolapse includes removal of the uterus (hysterectomy). An alternative procedure is one that supports the prolapsing uterus (hysteropexy) and pelvic organs. In this study, the investigators, including a RTI researcher, are comparing these two prolapse procedures. Women in this study have been randomly assigned to one of the two vaginal prolapse procedures. All participating women will complete questionnaires and a physical examination before and then for up to five years after surgery. This study began in March, 2013, and is expected to continue until about 2018. Recruitment and surgical procedures will occur over the first two years, and women enrolled in the study will continue to be followed afterwards for the additional three years.
