Current recommendations for imaging in the management of urologic traumas.

Three percent to 10% of trauma patients have genitourinary tract injuries. Radiologic imaging is essential for making the correct diagnosis and managing it appropriately. Which modality is appropriate is based on the mechanism of injury and patient presentation. Patients with pelvic injuries and gross hematuria should undergo either CT cystography or conventional cystography. Ultrasound is warranted in patients with scrotal trauma when physical exam is inconclusive. Patients with penetrating trauma to the external genitalia, who suffer blunt trauma to the penis, or who present with gross hematuria, blood at the meatus, inability to void, perineal/scrotal ecchymosis, or abnormal digital rectal exam should undergo retrograde urethrography. Using these criteria for imaging should lead to the proper diagnosis and minimize patient morbidity.
