disruption. Perineal hematoma usually resolves without complications.There is usually a history of a fall, and in some cases a history
of instrumentation. Bleeding from the urethra is usually present.
There is local pain into the perineum and sometimes massive perineal
hematoma. If voiding has occurred and extravasation is noted, sudden
swelling in the area will be present. If diagnosis has been delayed,
sepsis and severe infection may be present.Major blood loss usually does not occur from straddle injury.
If heavy bleeding does occur, local pressure for control, followed
by resuscitation, is required.The patient with urethral contusion shows no evidence of extravasation,

is allowed to void;..."
