This study was designed to assess the accuracy of the urine dipstick and its ability to predict injury to the urinary tract when compared to routine urinalysis: 1,485 patients had dipstick and microscopic urinalysis performed as part of their evaluation for blunt and penetrating trauma. Dipstick analysis was recorded as either positive or negative. Microhematuria was defined as greater than 0-1 RBC/HPF on microscopic analysis. ⋯ There were no cases of a missed injury in the group of 100 false negatives. Cost savings by conversion to the use of dipsticks would have saved our institution about $63,000 per year. It is concluded that the urinary dipstick is a safe, accurate, and reliable screening test for the presence or absence of hematuria in patients sustaining either blunt or penetrating abdominal trauma.

Case Reports
Bullet embolus to the right hepatic vein after a gunshot wound to the heart and its percutaneous retrieval.
Bullet emboli are rare and their management when in the venous circulation is controversial. A 26-year-old female with a gunshot wound to the heart, followed by embolization of the bullet to the right hepatic vein, had successful percutaneous retrieval of the bullet via a catheter inserted through the right femoral vein.

The Trauma Scores, CRAMS scales, and mechanisms of injury of 500 trauma patients were evaluated for their ability to identify a seriously injured patient. Serious injury was defined as one of the following: Injury Severity Score (ISS) greater than 15, or emergency-room Trauma Score less than or equal to 14, or injuries requiring greater than 3 days hospitalization, or death. ⋯ With these same mechanisms, the sensitivity of a CRAMS scale of less than or equal to 8 increased from 66% to 93%, with a specificity of 30%. The addition of these mechanisms of injury to standard field triage scoring appears to improve the identification of seriously injured patients while retaining an acceptable level of overtriage.
