If there is no discomfort after double J tube extraction, you can exercise appropriately for 1 to 2 days. After double J-tube extraction, the patient should exercise appropriately according to the patient’s own physical recovery condition. Generally, 1 to 2 days after extraction, the patient can do other light exercise such as brisk walking and strolling, but not strenuous exercise, and the strenuous exercise should be waited until about 1 month after the double J-tube extraction when the surgical trauma has been fully recovered. Before strenuous exercise, patients should find out whether the fluid and stenosis are relieved after double J-tube extraction, and if these problems exist, they need to be treated promptly. Moderate exercise can promote patients to expel stones and prevent urinary tract infection, and can be applied under the guidance of the doctor with drugs such as amoxicillin and levofloxacin. Hematuria occurs in some patients due to the friction between the double J tube and mucosa, which can be relieved after removal. After double J tube extraction, patients should pay attention to diet control, avoid spicy and stimulating food, and should consult a doctor in time when abnormal conditions occur.
