Current methods of diagnosis and management of ureteral injuries

A delay in diagnosis is the most important contributory factor in morbidity related to ureteral injury. The difficulty in making the diagnosis can be minimized by maintenance of a high index of suspicion and the timely performance of the appropriate radiographic and intraoperative evaluations. A decision on the timing of repair of the ureteral injury is based on the patient's overall condition, promptness of injury recognition, and proper injury staging. Ideally, when identified promptly, ureteral injuries should be repaired immediately. However, once there has been a delay in diagnosis or in the case of an unstable patient, temporizing measures can be used for urinary diversion. With the availability of simple, minimally invasive techniques to manage urinary extravasation and the absence of any risk of ureteral hemorrhage, ureteral reconstruction can be safely deferred until an opportune time during the recovery period. Successful surgical management requires familiarity with the broad reconstructive armamentarium and meticulous attention to the specific details of each procedure. Through adherence to the diagnostic and therapeutic principles outlined, complications can be minimized and renal preservation can be maximized in patients sustaining ureteral injuries.
