Ureteral anastomosis is a routine surgery, not a major surgery, with a low risk factor. Ureteral anastomosis is usually applied to ureteral stenosis, ureteral trauma, etc. Through the surgery, the ruptured ureter can be anastomosed, or the stenosed ureter can be resected, and after the resection, the severed ends can be anastomosed, and after the surgery, a ureteral stent is usually placed in the ureter. Therefore, ureteral anastomosis is a kind of routine surgery, which is not a major surgery, and the risk coefficient of the surgery is low; however, we should do a good job in the postoperative care after the surgery, and we should take more bed rest, avoid strenuous exercise, ensure sufficient water intake, urinate more often, pay attention to the hygiene of the lower body, and go to the doctor regularly for review to know the specific situation of recovery.
