Acute non-traumatic maternal illnesses in pregnancy: imaging approaches.

The imaging methods used to obtain diagnostic information for pregnant patients presenting with acute non-traumatic maternal illnesses have been reviewed. Conditions affecting the gastrointestinal tract, urinary tract, uterus, adnexae, central nervous system and chest have been investigated via a variety of imaging methods, which include ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), intravenous pyelography (IVP), angiography and fluoroscopy. The method of choice, application, and safety to the mother and fetus are considered for investigation of each condition.

Imaging of urethral disease: a pictorial review.

Retrograde urethrography and voiding cystourethrography are the modalities of choice for imaging the urethra. Cross-sectional imaging modalities, including ultrasonography, magnetic resonance (MR) imaging, and computed tomography, are useful for evaluating periurethral structures. Retrograde urethrography is the primary imaging modality for evaluating traumatic injuries and inflammatory and stricture diseases of the male urethra.

Imaging of bilateral ureteropelvic junction laceration from blunt trauma.

Bilateral ureteropelvic junction (UPJ) injury from blunt abdominal trauma is rare, with only seven previously reported cases, all of which were complete avulsions. Early and delayed computed tomography (CT) for visualization of the nephrographic and excretory renal phases, respectively, is essential to distinguish parenchymal from collecting system injury. Once UPJ injury is detected by CT, differentiation between laceration and avulsion is mandatory since laceration is treated nonoperatively, whereas avulsion requires surgical repair.

Urogenital trauma: imaging upper GU trauma.

Objectives: This article will define the current controversies and concepts in the classification, clinical presentation, imaging approaches and management of upper urinary tract trauma.

Materials And Methods, Results: This review will include the experience of the authors in the field of renal trauma over a 32-year period. Current thinking accepts the view that significant renal trauma is generally present when there is gross hematuria, signs of shock, or other clinical signs of severe injury.
