title: [Ureteral reconstruction after ureterorenoscopic injuries].
abstract: Ureteral injuries are caused by iatrogenic reasons in about 75% of cases. Among urological procedures ureterorenoscopy (URS) is mainly described as the reason for ureteral injury, although complication rates of URS are generally low. Injuries of the ureter are divided into five grades by the AAST. Grades I-II are referred to as partial and grades III-V as complex ureteral injuries. To avoid higher complication rates there should be no delay in confirmation of diagnosis and initiation of therapy. Correct therapy depends on grade of injury. Partial ureteral injuries are treated by endoscopic inlay of a ureteral stent for approximately 14-21 days. In complex injuries endoscopic ureteroureterostomy could be attempted but leads to rather poor long-term results depending on the length of devascularization of the injured ureter.Procedures with and without use of bowel for ureteral reconstruction and replacement have been described. The type of operative procedure should be selected based on location and degree of ureteral injury. Besides ureteral reconstruction, autotransplantation of the affected kidney can be required in individual cases.
