Hernia of the bladder through the inguinal canal, while rare, is a condition that must be borne in mind when operating on any hernia, either femoral or inguinal. Failure to recognize this rarity has led to disastrous results. Cooley, in Keen's "System of Surgery," says that but three cases of hernia of the bladder were encountered in a series of over 1,900 cases of hernia in patients operated on at the Hospital for Ruptured and Crippled.
