How long can the patient have intercourse after removing the double J-tube should be objectively analyzed based on the patient’s original condition as well as the factors of recovery of the current physical condition. First, if the patient implanted double J tube due to renal insufficiency caused by ureteral stenosis, and the patient’s renal insufficiency is still not recovered after double J tube removal, it is recommended that the patient should have sufficient rest and actively protect the kidney treatment. Waiting for 2-3 months after the complete recovery of renal function before coitus, can avoid the symptoms of renal insufficiency aggravated by excessive physical exertion during coitus. If the patient has double J tube because of ureteral injury, now the patient’s ureteral injury is completely recovered, and then the patient can remove the double J tube at this time, the prognosis is better. Patients can have intercourse one week after the removal of the tube, which will not cause serious impact on the human body.
