The time before and after the operation is about 1-2 hours. Patients need indwelling catheter outside the body, which is inconvenient to move. It's hard to get out of bed in the first two days. It usually takes three days to pull out the catheter. The doctor meant to keep a double J tube, but I took a photo on the fourth day. The doctor said that the tube was a little displaced and pulled it out directly. It's hard not to be anesthetized when extubating.
