Intraperitoneal rupture of pseudodiverticulum of bladder.

A case is presented of a pseudodiverticulum of the bladder which developed after a bladder rupture nine years previously. In this case, rupture of the pseudodiverticulum occurred intraperitoneally. The pseudodiverticulum communicated with the bladder via a small fish-mouthed opening surrounded by attenuated fibrotic bladder wall.
