The patients were divided into two groups according to the diameter of UAS (9.5F\/11.5F [Group 1] and 12F\/14F [Group 2]) placed during the operation. At the end of the operation, ureteral injury was checked visually using semirigid ureterorenoscopy and classified according to the ureter injury scale.
