Hello, I would be happy to help you with your question. It is not necessarily the standard of care to perform a bowel prep before a hysterectomy unless there is serious concern about adhesions and an increased risk for bowel injury during the surgery. Assuming that one bottle essentially cleaned your bowels out, that would probably be enough. This is a good question to direct back to the surgeon and the answer is likely based on information you may not have provided. I hope that this helps.
