Resumen

Although the majority of injuries to the genitourinary (GU) tract do not result in an immediate threat to life, failure to properly evaluate and treat these injuries may result in significant long-term patient morbidity. GU injuries frequently occur in the setting of multiple organ system trauma, and although other life-threatening injuries must be addressed first, the emergency department physician must be alert to clues pointing to the presence of these injuries. Signs such as flank hematoma, gross hematuria, or blood at the urethral meatus point to the presence of potentially serious genitourinary injuries, which require further evaluation and treatment.^{8 Carlin B.I., Resnick M.I.

Urologic injuries occur in 10% to 20% of major trauma patients and may be the result of either blunt or penetrating trauma.^{8 Carlin B.I., Resnick M.I. Indications and techniques for urologic evaluation of the trauma patient with suspected urologic injury Semin Urol 1995 ; 13 : 9-24

Initial detection of urologic injuries requires careful evaluation of the urinary system in the setting of concomitant injuries. Important clues to injury include the presence of lower rib or lumbar vertebral fractures, flank hematoma, pelvic fracture, abnormal prostate examination, blood at the external urethral meatus or gross hematuria. Despite the historical importance placed on the presence of microscopic hematuria, there is no indication to search for urologic injuries in a hemodynamically stable adult patient who has only this finding.^{39 Miller K.S., McAninch J.W.
