Figure 10a. Type III injury. (a) CT scan obtained through the perineal region shows extravasated contrast material (arrows) in the urinary tract below the UGD. (b) RUG image shows extravasated contrast material (arrows) in the urinary tract at the level of the UGD. A streak of contrast material (arrowheads) reaches the bladder, a finding compatible with a partial tear of the urethra. Injury to the membranous urethra, whether alone or in combination with injury above the UGD, constitutes a type III injury.
