The need for a urinary catheter for hysteroscopic surgery depends on the scope of the procedure, as well as the duration and size of the procedure. For general hysteroscopic surgery, such as endometrial polyp removal and submucosal fibroid removal, this procedure takes about half an hour to complete and usually does not require an indwelling urinary catheter, and the patient can get out of bed two hours after surgery, which has less impact on the patient. For hysteroscopic resection of the uterus or vaginal longitudinal septum, a compression balloon is given after the operation, which prevents the patient from getting out of bed in time and takes longer to operate. Such patients need to be given an indwelling urinary catheter, and the color and volume of urine should be observed. In addition, for patients whose surgery is combined with a laparoscopic procedure that requires a large trauma, an indwelling urinary catheter is also required. Hysteroscopic surgery does not require a urinary catheter in all patients, nor does it require one in all patients, depending on the size of the operation and the duration of the operation.
