Urinary bladder diverticulum as a content of femoral hernia: a case report and review of literature.

Background: Long standing increase of the intravesical pressure resulting from urinary bladder outlet obstruction can cause both secondary bladder diverticula and groin hernias. In rare cases, a diverticulum can be pulled by a hernia sac and becomes a component of the hernia itself. Such cases were encountered in inguinal, perineal and obturator hernias.
