The primary aim of this study is to determine if normal bladder function (the ability to empty the bladder during spontaneous urination) after surgical repair of pelvic organ prolapse returns faster in patients who have a retrograde voiding trial the day of surgery versus patients who have a retrograde voiding trial on postoperative day one. Half of participants will have a voiding trial 4 hours after surgery, while the other half will have the voiding trial postoperative day one.
