Whether or not a catheter is needed for hysteroscopic surgery depends on the patient’s specific situation and the content of the surgery, and cannot be generalized, it is recommended to consult the attending physician for clarification before the operation. Hysteroscopic surgery is generally a minimally invasive procedure, meaning that it is performed under a hysteroscope to strip away adhesive tissue and remove diseased tissue. For example, removing uterine polyps, removing submucosal fibroids, etc.. Generally the surgery is performed in a shorter period of time, the patient’s recovery is quicker, and the impact on the patient is relatively small, so a urinary catheter is not required. However, if the patient undergoes hysteroscopic vaginal mediastinum resection, etc., the time required for this kind of surgery may be longer, and in the postoperative period may also need to be given to the compression balloon, the patient can not get out of bed in time to move around, and generally need to stay in the urinary catheter, in addition, if the combination of laparotomy, the trauma is relatively large, it may also need to be placed on the urinary catheter.
