Ordinary bladder hernia is a fairly common condition, and many articles have been written about it. A recent and excellent one is that by Kollbert.1 Iason2 concludes from various statistical studies that the over-all incidence of bladder hernia is between 1% and 3%. In his own personal cases,3 however, he found the incidence to be 10% in men more than 50 years of age. Erdman,4 in a study of 8600 cases from the literature, found the incidence to be 4 per 1000.
Sliding hernia of the bladder is also fairly common, both in direct inguinal hernias and in femoral hernias.5 This paper, however, deals with sliding hernia of a diverticulum of the bladder. While I have encountered no description of this condition in the textbooks, it is probably not as rare a condition as one would judge from a perusal of the literature.
