Significance of hematuria after trauma.

There were 142 consecutive patients with post-traumatic hematuria evaluated prospectively during a 7-month period. Of these 142 cases 22 involved penetrating injuries and 120 were secondary to blunt trauma. There were 19 patients with 24 demonstrable genitourinary injuries at urologic injury. Only 8 of the 142 patients required an operation for the urologic injuries. The degree of hematuria did not correlate with the severity of injury. Liberal use of arteriography and renal scanning is proposed to delineate precisely the urologic injury.
