After cystectomy, the first and most critical thing to note is whether there is blood in the ureter or even a blood clot appearing to block the tube. The bladder should be flushed after cystectomy. The speed of the flushing solution should correlate with the color of the urinary catheter; if the color of the urinary catheter is dark, the flushing solution should be fast, and if the color of the urinary catheter is light, the speed of the flushing can be adjusted to slow down. If there is a blood clot, you should flush with pressure to flush out all the blood clots. It is important to pay attention to whether there is distension in the abdomen after the electrodesiccation, and distension is a concern for urine flowing into the abdomen after the bladder is removed by electrodesiccation. You should also pay attention to the possibility of urinary tract infection after surgery, you should drink more water, urinate more often, and antimicrobials must be used.
