In the treatment of some gynecological diseases, ureteral stents (double J stents) have been generally utilized in the prevention of ureteral injury. Nevertheless, if the ureteral stent is retained as a protective reminder during gynecological surgery, severe ureteral injury can be avoided. Hence, it is very essential to be familiar with the anatomy of ureter in gynecological surgery to prevent complications and morbidity.We demonstrate a case of a 49-year-old woman who presented with an electric burn broken ureteral stent in the gynecological surgery, but the ureter is only burned but not broken. This resulted in no abnormality being found during surgery. So, ureteroscopy is necessary to extract the ureteral stent and the patient is inserted with another new ureteral stent to repair the ureteral injury.The electric burn broken ureteral stent is difficult for discovering during the operation. And ureteroscopy is very crucial for the special situation of the ureteral injury.
