Usually, after the double J catheter is removed and observed for 48h, couples can have sex if no abnormal symptoms appear. Ureteral double J tube, because its end is located in the bladder, does not affect sexual life. When the ureteral double J tube is removed, it is taken out through the urethra, and the whole process does not involve the reproductive tract, so theoretically, it generally does not affect sexual life. However, if you have sex during this period, the pain may be aggravated. Therefore, it is recommended to observe the patient for 48 hours after the removal of the tube, and then have sex if there are no abnormal symptoms. In addition, it is recommended that women drink more water after the removal of the double-J tube, and if abnormal symptoms such as vaginal bleeding are found after intercourse, they can consult a doctor in time to improve the relevant examinations and standardize the treatment.
