A catheter will be routinely placed after the surgery, and during the period of the catheter placement, it is necessary to ensure that the daily water intake is about 1500-2000ml. At the same time, it is necessary to properly count the amount of urine in the drainage tube, observe the color of the urine in the drainage tube, and ensure that the drainage tube does not pull or fold. 2. 24 hours of fasting after surgery, after complete awakening from anesthesia, you can eat a liquid diet, and after 24 hours, you can return to a normal diet. 3. 24 hours of bed rest after surgery, and after 24 hours, you can move to the ground as appropriate. 4. local disinfection of the urethral opening is required after surgery.
