You can usually urinate normally after the catheter is removed. After the catheter is removed, the patient needs to urinate on his own to complete the whole process of urination. The catheter is inserted mainly to drain the urine from the bladder, and is suitable for patients who have difficulty in urinating, or if the operation takes too long and a catheter is needed intraoperatively to drain the urine from the bladder in time to prevent urinary incontinence. After the catheter is removed, patients are advised to drink more water, probably more than 2000ml of water, to make the urinary system produce more urine, so that a large amount of urine can be discharged and the urethra can be flushed, so it is good for the body.
