All subjects will be predetermined by their surgeon to undergo sacrospinous ligament colpopexy for management of vaginal apex prolapse after hysterectomy. The participants will then be randomized to one of two groups: "local analgesia injection" or "normal saline injection" according to a computer-generated randomization schedule with random block sizes with the use of the SAS statistical software package (SAS Institute, Cary, NC). Randomization will be done by a nurse coordinator who will not be involved in participant recruitment or injection at the time of surgery. All patients and providers will be blinded to their assignment. The assignment will be kept in an envelope which will be given to the pharmacy the day of the patient's scheduled procedure. The pharmacy will then dispense the correct intervention based on the randomization.
