According to the search results, cystoscopy can be performed using a local anesthetic to numb the urethra, and if needed, it can also be performed under sedation. The type of sedation used depends on the patients needs and the reason for the examination. Sedation can be administered through an IV, and it can be a sedative or a general anesthetic. If a sedative is given, the patient will feel sleepy and relaxed during the procedure, but they will still be aware. If a general anesthetic is given, the patient will not be aware during the procedure. The type of sedation used is not specified in the search results, but it is likely that the choice of sedation will be made by the doctor based on the patients medical history and the specific circumstances of the procedure.
