These usually occur as a result of surgical procedures, and the percentage when radical surgery is done may reach as high as 33%. Our exhibit is intended to outline the cause, symptomatology, and management of such trauma.Summary  Ureteral injury is usually iatrogenic. Its management often entails preliminary diversion by nephrostomy. Preliminary passage of ureteral catheters is the single measure which will enable the surgeon to identify the ureter prior to injury, and which will facilitate recognition of the injury when it occurs.2065 Adelbert Road (6).
