Imaging of Renal Trauma : A Comprehen - sive Review 1 LEARNING

چکیده
Computed tomography (CT) is the modality of choice in the evaluation of blunt renal injury. Intravenous urography is used primarily for gross assessment of renal function in hemodynamically unstable patients. Selective renal arteriography or venography can provide detailed information regarding vascular injury. Retrograde pyelography is valuable in assessing ureteral and renal pelvic integrity in suspected ureteropelvic junction injury. Ultrasonography is useful in detecting hemoperitoneum in patients with suspected intraperitoneal injury but has limited value in evaluating those with suspected extraperitoneal injury. Occasionally, radionuclide renal scintigraphy or magnetic resonance imaging may prove helpful. Renal injuries can be classified into four large categories based on imaging findings. Category I renal injuries include minor cortical contusion, subcapsular hematoma, minor laceration with limited perinephric hematoma, and small cortical infarct. Category II lesions include major renal lacerations extending to the medulla with or without involvement of the collecting system and segmental renal infarct. Category III lesions are catastrophic renal injuries and include multiple renal lacerations and vascular injury involving the renal pedicle. Category IV injuries are ureteropelvic junction injuries. CT is particularly useful in evaluating traumatic injuries to kidneys with preexisting abnormalities and can help assess the extent of penetrating injuries in selected patients with limited posterior stab wounds. Integration of the imaging findings in renal injury with clinical information is critical in developing a treatment plan.

Renal trauma imaging: Diagnosis and management. A pictorial review
BACKGROUND The purpose of this review is to illustrate and discuss the spectrum of imaging findings, particularly computed tomography (CT), of blunt and penetrating renal trauma, based on our own materials, according to the American Association for Surgery of Trauma (AAST) renal injury grading scale. The article also indicates the conditions in which interventional radiology procedures can be a...
متن کاملAggressive Desmoid Tumor Mimicking Breast Cancer
sive disease (1). An accurate diagnosis is difficult because of the similar clinical and imaging findings to a breast malignancy. Desmoid tumors are found mainly in young women and in patients with previous surgical trauma or reconstruction. We report the case of a 72year-old female presenting with an aggressive desmoid tumor that mimicked breast carcinoma but was not associated with previous t...
متن کاملNonoperative management of blunt renal trauma: Is routine early follow-up imaging necessary?
BACKGROUND There is no consensus on the role of routine follow-up imaging during nonoperative management of blunt renal trauma. We reviewed our experience with nonoperative management of blunt renal injuries in order to evaluate the utility of routine early follow-up imaging. METHODS We reviewed all cases of blunt renal injury admitted for nonoperative management at our institution between 1/...
