Isolated Proximal Ureteric Injury after a Penetrating Stab Wound to Lumbar Region

Urological injuries fall far behind other abdominal injuries when it comes to involvement during trauma. Amongst urological trauma, ureteral injuries account for 1-2.5%. An isolated ureteral injury is infrequently encountered because of a safe retroperitoneal location and a smaller diameter of the ureter as compared to other organs. A high index of suspicion is needed as a delayed or missed diagnosis of penetrating ureteral trauma or an unrecognised and mismanaged ureteral injury can lead to significant complications, including formation of urinoma, abscess, ureteral stricture or urinary fistula, and potential loss of the ipsilateral kidney. The present case report is of a 35-year-old male who presented to the Emergency Department of tertiary care hospital with a stab injury in left lumbar region and was diagnosed with isolated ureteral injury on Contrast Enhanced Computed Tomography (CECT). Without much delay, ureteroscopy was done, a double J stent was placed and ureteroureterostomy was performed.
