B. Imaging the bladder and urethra U.G. Mueller-Lisse; Munich/DE Trauma to the bladder and urethra is seldom an isolated injury, such as in selfinserted urethral foreign objects in men. Often, the lower urinary tract (LUT) is one site of a more complex trauma injury process involving the pelvis and abdomen. Trauma scan (TS) protocols for computed tomography (CT) have been widely applied in emergency radiology since the advent of multidetector-row CT (MDCT). Acute LUT injury has thus become subject to TS as the primary imaging modality, with intravenous contrast media being used in various phases of its distribution, potentially including arterial, venous and excretory, as in CT-urography (CTU). Delayed diagnosis appears to rarely affect LUT in TS patients. Cystography and urethrography may play a complimentary role and remain useful modalities in the initial evaluation and follow-up of LUT trauma that may determine urological management. Complications of LUT trauma, such as urine leaks, urinomas and fistulas, are increasingly being diagnosed by means of MDCT. However, particularly in LUT fistulas, voiding cystourethrography and urethrography are still important. Complications of LUT injury may require imaging-guided interventional procedures, whether by means of fluoroscopy, ultrasonography or CT. Learning Objectives:
