[Management of ureteral injuries]

Ureteral injuries account for less than 3% of genitourinary injuries. Most of them are caused iatrogenically during abdominal surgery. The symptoms are often non-specific and do not aid in diagnosis. The later the injury is detected, the more often complications occur. Therefore, in such situations it is important to consider the possibility of ureteral injury and initiate further diagnostic steps as soon as possible. A variety of diagnostic tests are available. In addition to the direct inspection of the ureters and retrograde ureteropyelography, computed tomography (CT) urography is routinely used. Based on the time of diagnosis as well as the extent and the localization of the injury, the further procedure can be determined. For minor injuries, the insertion of a ureteral splint is usually the treatment of choice. In the case of higher grade damage, operative reconstruction by one of several possible surgical procedures is indicated.
