Ultrasound has emerged as the diagnostic imaging modality of choice in the evaluation of patients with scrotal trauma. Most studies of testicular rupture show great accuracy with virtually no instances of false-positive or false-negative diagnoses. ⋯ In patients with suspected testicular rupture, an accurate diagnosis followed by prompt surgical repair is the key to preservation of testicular function. Ultrasound is an extremely useful adjunct to the physical examination in cases of blunt scrotal trauma both for the differential diagnosis of the enlarged scrotum and for determining the necessity for emergency surgery.

Ureteral obstruction by intramural bullet, buckshot, or related missle following penetrating abdominal trauma is rare; a search of the literature revealed only 4 previously described cases [1-4]. A fifth case of a bullet migrating from the renal pelvis to the ureter has been reported at autopsy [5]. We present 2 new cases of delayed symptomatic ureteral obstruction ("bullet colic") after abdominal gunshot wounds.

Prostatic abscess appears on computed tomography (CT) as multiple, well-demarcated fluid collections within the prostate gland and/or periprostatic tissues. Since prostatic abscess may not be differentiated from other prostatic disease on the basis of history and physical examination alone, CT can contribute significantly to establishing this diagnosis. ⋯ By defining the extent of the disease, CT can guide selection of an optimal surgical drainage procedure. CT can be used effectively to monitor the treatment of prostatic abscess.
