This is a randomized controlled double blinded trial in which patients will be assigned to receive saline (control group) or bupivacaine 0.5% with epinephrine 1:200,000 (treatment group). The randomization will be performed through a computerized system in the pharmacy at the pharmacy of the hospital where the study is occurring. The randomization will occur once the patient has consented to the study. The treatment arm of the study will receive a total injection of 14ml of bupivacaine with 7ml directed into the right uterosacral ligament and 7ml into the left uterosacral ligament. The control arm of the study will receive a total injection of 14ml of normal saline with 7ml directed into the right uterosacral ligament and 7ml into the left uterosacral ligament. These injections will take place after the uterus and cervix have been surgically removed and the vaginal cuff has been surgically closed.
