title: Hematuria as a predictor of abdominal injury after blunt trauma.
abstract: Among the 1,484 patients included in the Renal Trauma Project with evidence of blunt trauma and hematuria, 160 patients were found to have both hematuria and a significant intra-abdominal injury not related to the genitourinary system. The incidence of abdominal injury generally increased with the degree of hematuria, approaching 24% in patients with gross hematuria. For each category of degree of hematuria, patients with shock had a significantly higher incidence of abdominal injury (p < 0.05) than patients without shock. The incidence of abdominal injury in patients with microscopic hematuria and shock was 29%, and it was 65% for patients with both gross hematuria and shock. All patients with gross hematuria after blunt abdominal trauma and all patients with microscopic hematuria and a history of shock should be evaluated for both urologic and extra-renal abdominal injuries.
