Ureteral diverticulum is a rare urological condition with only 45 cases described in the literature. We present a 52 yr old male with polytrauma following road traffic accident who presented to our emergency department. After initial stabilisation and further evaluatuion he was found to have multiple solid organ injury and suspected lower ureteric injury due to contrast extravasation mimicking ureteric injury. On evaluation by Retrograde pyelogram diagnosis of lower ureteric diverticulum was confimed . In conclusion Ureteral diverticulum may present as an incidental finding or with a secondary complication. Conservative management is advocated in the literature for non–complicated cases. Retrograde pyelography is the diagnostic tool of choice.
