Penetrating ureteral injuries: the impact of associated injuries on management.

The ideal management for penetrating ureteral trauma is primary repair, but the effect of other abdominal injuries might preclude this. We attempted to determine what factors could be used to predict a poor outcome of a ureteral anastomosis, so that the initial management can be modified appropriately. The case notes of 41 patients treated for penetrating ureteral trauma were studied retrospectively. Any factors that could influence postoperative complications and outcome were statistically analyzed in order to determine which could be used pre- or intraoperatively to indicate a poor prognosis for the ureteral anastomosis. The presence of shock on admission (P = 0.013), intraoperative bleeding (P = 0.006), colonic injury and specifically injury requiring colectomy (P = 0.006) were associated with a high complication and mortality rate. Patients presenting with penetrating ureteral trauma who are severely shocked and have complicated intraoperative hemostasis and patients who require colectomy should not have a primary ureteral anastomosis, but rather initial ureteral exteriorization or even nephrectomy.
