Intravesical Herniation of Small Bowel After Bladder Perforation

Abstract
Intravesical small bowel herniation is a rare complication of bladder perforation, with only 1 case reported previously. We describe 2 additional patients in whom the diagnosis of bladder perforation was delayed or made difficult because the herniated small bowel presented as a filling defect without significant extravasation of contrast medium on cystography. In both patients additional investigative procedures were necessary to establish the diagnosis preoperatively.
