What is the appropriate workup for blunt genitourinary trauma in hemodynamically stable patients?

In cases of blunt genitourinary trauma in hemodynamically stable patients, the most appropriate workup involves contrast-enhanced CT imaging. This imaging modality is favored because it allows for comprehensive evaluation of the kidneys, ureters, bladder, and surrounding structures. A contrast-enhanced CT scan can effectively identify injuries such as renal lacerations, hematomas, and other soft tissue injuries, providing critical information for deciding on management.

Urinalysis and plain X-ray, while useful in certain contexts, do not provide sufficient detail to evaluate complex traumas. Urinalysis can indicate hematuria but does not diagnose the extent of injury, and plain radiography has limited utility in detecting soft tissue injuries or subtle fractures compared to CT imaging.

Magnetic resonance imaging is not typically used as the first-line imaging modality for trauma cases due to its longer acquisition time and less availability in acute settings. It may be used in specific cases when radiation exposure is of significant concern, especially in young patients, but it is not standard practice for initial management.

Diagnostic laparotomy is a highly invasive procedure that is generally reserved for hemodynamically unstable patients or when there is a strong clinical suspicion of an intra-abdominal injury that requires surgical intervention. In hemod
