A simple football injury leading to a grade 4 renal trauma.

This case highlights the need for cautious management and serial regular examination of trauma patients. A 22-year-old Caucasian male presented to the emergency department 4 h following an injury sustained during football training. He complained of the immediate onset of severe left upper quadrant and left flank pain. He subsequently developed frank haematuria. On initial review, he was haemodynamically stable. CT of the abdomen and pelvis showed a grade 4 renal trauma. Over the following 36 h, he remained haemodynamically stable. On serial abdominal examinations however, he developed a rigid abdomen and was noted to have a haemoglobin drop. Interval CT scan showed a progression of his injury and the presence of a haemoperitoneum. An emergency laparotomy was performed resulting in a left nephrectomy. He made an uneventful recovery.
