Reports of the utility of CT in ureteral trauma are still limited to small numbers of cases. Ureteral injuries can be difficult to diagnose on CT. If the urinary extravasation from the ureteral injury is contained by Gerota fascia, the extent of medial leakage can be small, obscuring the diagnosis (Kenney et al, 1987). It is also known that ureteral injuries often manifest with absence of contrast in the ureter on delayed images. This underscores the absolute necessity of tracing both ureters throughout their entire course on CT scans obtained to evaluate urogenital injuries (Townsend and DeFalco, 1995). In addition, because modern helical CT scanners can obtain images before intravenous contrast dye is excreted in the urine, delayed images must be obtained (5 to 20 minutes after contrast injection) to allow contrast material to extravasate from the injured collecting system, renal pelvis, or ureter (Brown et al, 1998; Mulligan et al, 1998; Kawashima et al, 2001). Because ureteral injuries are often detected late, periureteral urinoma seen on delayed CT scans may be diagnostic (Gayer et al, 2002). In reported series, all patients with significant ureteropelvic laceration, for instance, had either medial extravasation of contrast material or nonopacification of the ipsilateral ureter on CT (Kenney et al, 1987; Kawashima et al, 2001). Such findings should always raise suspicion for ureteral injury. Retrograde Ureterography. Retrograde ureterograms, the most sensitive radiographic test for ureteral injury, are used in some centers as a primary diagnostic technique to detect acute ureteral injuries (Campbell et al, 1992); however, the authors tend to use

Bladder Trauma

Bladder injuries can be due to external (blunt or penetrating) or iatrogenic trauma. Iatrogenic trauma is caused by external laceration or internal perforation (mainly during TURB). Blunt bladder injuries are strongly associated with pelvic fractures. Bladder injuries are classified as extraperitoneal, intraperitoneal or combined.

exploration (40%), and orchiectomy (15%) (Cass and Luxenberg, 1988). Significant hematoceles should also be explored, regardless of imaging studies, because up to 80% are caused by testicular rupture (Vaccaro et al, 1986). Penetrating scrotal injuries should be surgically explored to inspect for vascular and vasal injury; as in blunt trauma the same principles of salvage, hemostasis, and reconstruction apply. The vas deferens is injured in 7% to 9% of scrotal gunshot wounds (Gomez et al, 1993; Brandes et al, 1995). The injured vas should be ligated with nonabsorbable suture and delayed reconstruction performed if necessary. Approximately
