No medication is usually needed before catheter removal, and antibiotics are needed if there is a urinary tract infection before catheter removal. Removing a urinary catheter is a relatively simple operation, and most often does not cause significant discomfort or serious complications, such as severe pain, bleeding, or infection, so there is no need to take medication before removal. Urinary catheter extraction does not require antibacterial drugs because it is a sterile operation; it does not cause severe pain when removing the urinary catheter, so there is no need to take painkillers; the removal of the urinary catheter indicates that urinary function has more often than not been restored to normal, and more often than not it will not cause a lot of bleeding and so on, so there is no need to take drugs such as hemostatic drugs. Except for special circumstances, if the patient with urinary tract infection, you need to take antibacterial drugs before and after the removal of the tube, such as amoxicillin. Patients who have been catheterized for a long time will have decreased bladder compliance, so they need to exercise the function of the bladder before removing the urinary catheter, and they can choose to clip the urinary catheter closed at regular intervals to exercise the function of the bladder. It is recommended that patients go to the hospital in time to improve the auxiliary examination, treatment by professional physicians, drugs need to be used under the guidance of professional physicians.
