Ureteral stenosis in the pelvis, upper and middle ureteral stenosis, and lower ureteral stenosis can be dilated or shaped. After surgery, a D-J tube is placed for a period of time. 2.Percutaneous renal puncture is performed to cut the stenosis and place a balloon to dilate it. Ureteroscopic dilation of the stenosis is performed and the D-J tube is left in place after the dilation. Now there is a better overlapping stent compared to DJ tube, which can improve the success rate after dilatation and the quality of life of the patient during the period with the tube. 3, postoperative care should be strengthened, to keep urine flowing, drink more water, preferably do not hold urine.
