After a flexible ureteroscopy, a double J tube is usually left in place for local support. Patients should drink plenty of water and urinate regularly after surgery, and observe whether there is any blood or cloudy urine in the urine. A routine urinalysis will be performed to determine if there is a urinary tract infection. If you miss a certain period of time, it will lead to the formation of secondary stones around the double J-tube, and it will be more difficult to pull out the double J-tube. There is no special attention needed after the soft microscopy, mainly bed rest on the postoperative day. If you are able to get up and move around after surgery, it is recommended to move around as early as possible to facilitate the recovery of the disease after surgery, and you should keep drinking enough water to prevent infection or catching cold.
