2024年12月14日 · CT cystography is performed by instilling water-soluble contrast into the bladder through a urinary catheter. It may be combined with standard CT to evaluate the upper tracts. An extraluminal position of a urinary catheter indicates bladder rupture, although, in an underfilled bladder, the tip of the catheter may falsely appear extraluminal.

This online presentation reviews the mechanisms of traumatic urinary bladder injury, with case illustrations of the types of urinary bladder injury according to the commonly used radiologic classification system, discusses optimal CT cystographic protocol and technique, and highlights potential diagnostic and interpretive pitfalls to aid in ...

2024年6月14日 · Bladder injuries can be categorized as one of two types: Intraperitoneal rupture. This involves the dome and causes urine to spill into the peritoneal cavity and surround the bowel loops. Extraperitoneal rupture. This is usually anterior and the leaking urine is confined to the space surrounding the bladder.

Extraperitoneal Bladder Rupture. CT of the pelvis following contrast shows a Foley catheter (white arrow) in the lumen of the urinary bladder with ladder in the extraperitoneal spaces (red arrows). Intraperitoneal bladder rupture ; Usually iatrogenic or secondary to penetrating injury

Contrast-enhanced CT is the primary imaging technique used to evaluate the upper and lower urinary tract for trauma. Cystography and urethrography remain useful techniques in the initial evaluation and follow-up of trauma to the urinary bladder and urethra.

Gross hematuria, pelvic fluid, and specific pelvic fractures were highly correlated with bladder rupture; identification of these findings may help in selection of trauma patients for CT cystography.

2019年11月15日 · Compared with conventional cystography, CT cystography can expedite triage of patients with suspected urinary bladder trauma and as an adjunct to routine abdominopelvic CT in multi-trauma patients, and is more accurate in detecting as well as …

2000年9月1日 · Computed tomographic (CT) cystography has been advocated in lieu of conventional cystography in the initial work-up of patients with suspected urinary bladder trauma. CT cystography was applied to a classification scheme for bladder injury based on the degree of wall injury and anatomic location and demonstrated characteristic imaging features ...

2019年9月7日 · Computed tomography has taken a central role in the imaging of the ureters and bladder. This article reviews the anatomic relationships, mechanisms of injury, and clinical presentation to help physicians determine when bladder and ureteral injuries should be suspected and further imaging should be pursued.

CT cystography is accurate for diagnosing bladder rupture. Sagittal and coronal multiplanar reformations may be helpful in identifying most sites of bladder rupture. Bladder rupture is an uncommon injury, occurring in 10% of patients with pelvic fractures. However, 83% of patients with bladder rupture have a pelvic fracture [1].
