This will be a randomized control trial. Patients undergoing total laparoscopic hysterectomy (TLH) for benign conditions will be invited and consented to participate in the study prior to the day of their surgery. Each patient will be contacted by one of the study investigators and presented with the study including the risks, benefits, and follow up requirements. She will be given the option to participate and if agrees, she will sign a consent form. All enrolled participants will have a post-void residual (PVR) checked and recorded in the clinic using the bladder scanner that is available to us. The enrolled participants will also be asked to complete the Patient Perception of Bladder Condition (PPBC) and the Incontinence Impact Questionnaire-Short Form (IIQ-7) and the completed forms will be collected by the research team (see attached "Preoperative participant questionnaire").9,10 Each consented participant will be randomized to receive a post-operative backfill void trial or an autofill void trial on the day of her surgery. The participant will not be told of her randomization group pre-operatively; however, the surgical team will be aware of the randomization.
