Abstract

PURPOSE
Retrograde cystography is the method of choice for the diagnosis of bladder rupture, but recently usage of abdominopelvic CTs has increased at emergency rooms (ERs).
METHODS
We reviewed the medical records and radiographs of 36 patients with bladder rupture. Of these, twenty seven patients underwent abdominopelvic CT, delayed kidney-ureter-bladder, and retrograde cystography. Delayed KUB was done about 30 minutes after the abdominopelvic CT.
RESULTS
Of the 36 patients with bladder ruptures, 25 had intraperitoneal bladder ruptures, and 9 had extraperitoneal ruptures. One patient had a bladder contusion, and the last patient had combined bladder rupture with intraperitoneal and extraperitoneal ruptures. The abdominopelvic CTs for the bladder rupture patients showed ascites with low density, bladder-wall thickening, perivesical fluid, and irregular bladder contour. In the 24 patients who underwent delayed KUB, spillage of dye was noted intraperitoneal or extraperitoneal cavity.
CONCLUSION
If abdominopelvic CT shows ascites with low density, bladder-wall thickening, perivesical fluid, and/or an irregular bladder contour, then a delayed KUB would be a useful method for diagnosing the bladder rupture.
