Isolated intraperitoneal bladder rupture in patients with alcohol intoxication and minor abdominal trauma.

Rupture of the urinary bladder secondary to abdominal trauma is uncommon and is usually associated with visceral or bone injuries; less than 10% of all cases occur without associated injuries. We present two cases of bladder rupture in intoxicated patients after minor abdominal trauma and without evidence of associated injuries. Given the absence of any symptoms in either case, we did not initially suspect bladder rupture. One of the two patients also presented with an intravesical herniation of the rectosigmoidal junction.
