At the time of the surgery, the research coordinator will open a sealed envelope containing the patient's assignment to partial bladder filling or no bladder filling. The research coordinator will then notify the surgeon via secure phone call or secure messaging service and the patient/subject will have their bladder partially filled or completely emptied as relayed to the surgeon at the end of the procedure in the Operating Room, unless there are issues of patient safety or operative complications. In the patients who are chosen for partial bladder filling, the bladder will be back-filled with 150 cc of normal saline and then the Foley catheter will be removed at the end of the procedure. In patients who have no bladder filling, the bladder will be completely emptied and then the Foley catheter will be removed. One of the providers who perform the gynecological surgical procedures will be responsible for back-filling or completely emptying the bladder with the Foley catheter.
