Figure 13b. Distortion or obscuration of the prostatic contour. (a) CT scan of a patient with a type I urethral injury shows absence of the normal prostatic outline. A periprostatic hematoma obliterates the fat planes. p = prostatic parenchyma. (b) CT scan of another patient shows a fracture of the superior pubic ramus (arrow) with a preserved prostatic contour and preserved preprostatic fat planes. RUG images were normal.
