During the surgery, a ureteral stent tube will be left inside the ureter, the main purpose of which is to dilate the lumen of the ureter, which will help to urinate smoothly during the recovery period, but it is inevitable that there will be urinary leakage. Normally, the stent tube can be removed about one month after ureteral anastomosis and there will be no urine leakage.
