Ureteral stenosis postoperative recovery precautions include timely removal of the double J tube, drink plenty of water, anti-inflammatory, and the treatment of surgery-induced ureteral stenosis. 1. Remove the double J-tube in time: there is a double J-tube in the body after the operation, which usually needs to be removed in 2~3 months, not more than one year. 2. Drink more water: After surgery, you can promote metabolism by drinking more water to avoid urinary tract infection. 3. Anti-inflammatory: If the postoperative check of urine routine reveals inflammation, antibacterial and anti-inflammatory drugs, such as levofloxacin, need to be used, and the medication should be under the guidance of the doctor. 4. Treatment of ureteral stenosis: If scarring is formed after surgery, scarring compression of the surrounding tissues can cause recurrence of ureteral stenosis, which requires timely surgical release. After ureteral stenosis surgery, you need to follow the doctor’s instructions for rehabilitation and long-term follow-up, as well as regular checkups to see how the condition is recovering, and intervene promptly if there are any abnormalities.
