The pathologic mechanism responsible for ureteral injuries is no different now than in past decades. Nowadays, however, we distinguish diagnostically between partial traumatic tears and complete ones. This distinction leads to different therapeutic strategies: endoscopic surgery for the former and open surgery for the latter. We further distinguish between the pathophysiology of closed and of open urinomas; the latter have a less favourable prognosis. This means that the treatment strategies and the degree of urgency are also different. We report on 16 cases treated over the past 22 years and review the international literature.
