RUG cystogram

A retrograde urethrogram is often combined with an anterograde cystogram, typically performed through a suprapubic tube placed at the time of injury. In this radiograph, the retrograde urethrogram shows an obliterative component in the proximal bulbar/distal membranous urethra. The anterograde cystogram helps delineate the entire length of the obliterated segment of the pelvic fracture urethral distraction defect (outlined by the bracket). Combining these two techniques in an "up-and-down-o-gram" helps the surgeon delineate the length of the obliterated segment for surgical planning.
