CT findings of spontaneous intraperitoneal rupture of the urinary bladder: two case reports.
We report two cases of spontaneous bladder rupture. Preoperative diagnosis was difficult and the correct diagnosis was made at surgery. Reviewing the initial abdominopelvic CT of our second patient, the bladder wall defect and blood attenuation near the bladder were observed. These findings were consistent with the operative findings, and would have led to correct preoperative diagnosis if we had had sufficient knowledge of spontaneous bladder rupture. Under urinary catheterization, ascites and free intraperitoneal air were identified in both patients. These findings were indistinguishable from those for bowel perforation, which was our preoperative diagnosis. Significant changes in ascites volume between pre and post urinary catheterization can be an indication of spontaneous bladder rupture.
