title: Indications for retrograde cystourethrography in trauma.
abstract: Injuries to the lower genitourinary tract may occur with penetrating or severe blunt lower abdominal trauma. Commonly associated findings are pelvic fractures and gross hematuria or a bloody urethral discharge. Retrograde cystourethrography should be performed in all cases of penetrating trauma when lower genitourinary tract injury is suspected. We recommend retrograde urethrography in male patients with a pelvic fracture or significant lower abdominal or perineal trauma without a fracture when associated with gross hematuria, a bloody urethral discharge, inability to void, swelling, ecchymosis or hematoma of the perineum or penis, or a "high-riding" or boggy prostate. Cystography should follow urethrography after a urethral injury has been excluded.
