For patients who have undergone kidney stone surgery, the doctor will routinely leave the double J tube in the ureter, and it is not recommended to have conjugal life in this case. This is because during conjugal life, the constant movement of the body affects the physiological changes of the waist, which can lead to the dislocation of the double J tube. Once the double J tube is dislodged, if it enters the bladder or urethra, it will lose its normal physiological function of support. If the double J-tube is displaced, it may cause urinary bleeding or ureteral stenosis or recurrence of kidney stones, so patients should not have conjugal life after kidney stone surgery with a double J-tube in place. After the removal of the double J tube, patients should observe for 2-3 days to see if there is any abnormality in urination and whether there are any uncomfortable symptoms, such as hidden pain and soreness in the lower back, and after the routine removal of the double J tube, they can usually have conjugal life in 6-8 weeks.
