How long can patients have intercourse after the removal of the double J tube, which depends on the patient’s original condition and the factors of recovery of the current physical condition for objective analysis. First, if the patient is implanted with a double J tube due to renal insufficiency caused by ureteral stenosis, after the removal of the double J tube, the patient’s renal insufficiency still has not recovered, at this time, it is recommended that the patient take sufficient rest and actively protect the kidney treatment. After 2-3 months of complete recovery of renal function, intercourse can be avoided due to excessive physical exertion during intercourse, resulting in aggravation of the symptoms of renal insufficiency. Second, if the patient is placed into double J tube due to ureteral injury, now the patient has completely recovered from ureteral injury, the prognosis is better if the double J tube is removed at this time. Patients can have intercourse one week after the removal of the tube, which will not cause serious impact on the human body.
