Complete upper urinary tract obstruction caused by penetrating pellet injury of the ureterintroduction

Ureteral injuries due to gunshots are tend to be misdiagnosed because of concomitant vascular and intraabdominal organ wounds. Our case is a 23-year-old man who was admitted to the hospital with multiple abdominal gunshot wounds. Laboratory findings showed worsening anemia, and the computed tomography (CT) scan showed multiple lead bullets inside the abdomen and retroperitoneum. Patient was then taken to the operation room for laparatomy. There were many intestinal injuries and also a stable retroperitoneal hematoma. There was no ureteral injury mentioned in the operation note or the initial CT report. Two weeks after this operation, the patient developed significant urine leakage from the abdominal wounds. Ureteral J stent placement was our first choice of treatment. This was complicated with a late ureteral obstruction. The final treatment was an ureteroureterostomy. Diagnosing ureteral injuries due to traumatic causes can be hard in most of the cases. Physicians should consider early evaluation of the patient for ureteral leakage if there is suspicion about ureteral injury.
